Lydia DePillis has written the best piece on the FDA that I have ever read in a mainstream news publication. It gets everything right and yes it frankly verifies everything that I have been saying about the FDA and rapid tests for the last year and a half. I wish it had been written earlier but I suppose that illustrates how difficult it is to radically change people’s mindset from the FDA as protector to the FDA as threat. The sub head is:
Irene Bosch developed a quick, inexpensive COVID-19 test in early 2020. The Harvard-trained scientist already had a factory set up. But she was stymied by an FDA process experts say made no sense.
The piece recounts how cheap, rapid tests could have been approved in March of 2020! Here’s the opening bit:
When COVID-19 started sweeping across America in the spring of 2020, Irene Bosch knew she was in a unique position to help.
The Harvard-trained scientist had just developed quick, inexpensive tests for several tropical diseases, and her method could be adapted for the novel coronavirus. So Bosch and the company she had co-founded two years earlier seemed well-suited to address an enormous testing shortage.
E25Bio — named after the massive red brick building at MIT that houses the lab where Bosch worked — already had support from the National Institutes of Health, along with a consortium of investors led by MIT.
Within a few weeks, Bosch and her colleagues had a test that would detect coronavirus in 15 minutes and produce a red line on a little chemical strip. The factory where they were planning to make tests for dengue fever could quickly retool to produce at least 100,000 COVID-19 tests per week, she said, priced at less than $10 apiece, or cheaper at a higher scale.
“We are excited about what E25Bio is capable of shipping in a short amount of time: a test that is significantly cheaper, more affordable, and available at-home,” said firm founder Vinod Khosla. (Disclosure: Khosla’s daughter Anu Khosla is on ProPublica’s board.)
On March 21 — when the U.S. had recorded only a few hundred COVID-19 deaths — Bosch submitted the test for emergency authorization, a process the Food and Drug Administration uses to expedite tests and treatments.
You know how the story ends but really READ the WHOLE THING.
If you have been following MR for the last 18 months (or 18 years!) you won’t find much new in this ProPublica piece on FDA delay in approving rapid tests but, other than being late to the game, it’s a good piece. Two points are worth emphasizing. First, some of the problem has been simple bureaucratic delay and inefficiency.
In late May, WHPM head of international sales Chris Patterson said, the company got a confusing email from its FDA reviewer asking for information that had in fact already been provided. WHPM responded within two days. Months passed. In September, after a bit more back and forth, the FDA wrote to say it had identified other deficiencies, and wouldn’t review the rest of the application. Even if WHPM fixed the issues, the application would be “deprioritized,” or moved to the back of the line.
“We spent our own million dollars developing this thing, at their encouragement, and then they just treat you like a criminal,” said Patterson. Meanwhile, the WHPM rapid test has been approved in Mexico and the European Union, where the company has received large orders.
An FDA scientist who vetted COVID-19 test applications told ProPublica he became so frustrated by delays that he quit the agency earlier this year. “They’re neither denying the bad ones or approving the good ones,” he said, asking to remain anonymous because his current work requires dealing with the agency.
Second, the FDA has engaged in regulatory nationalism–refusing to look at trial data from patients in other countries. This is madness when India does it and madness when the US does it.
For example, the biopharmaceutical giant Roche told ProPublica that it submitted a home test in early 2021, but it was rejected by the FDA because the trials had been done partly in Europe. The test had compared favorably with Abbott’s rapid test, and received European Union approval in June. The company plans to resubmit an application by the end of the year.
A smaller company, which didn’t want to be named because it has other contracts with the U.S. government, withdrew its pre-application for a rapid antigen test with integrated smartphone-based reporting because it heard its trial data from India — collected as the delta variant was surging there — wouldn’t be accepted. Doing the trials in the U.S. would have cost millions.

Laboratory developed tests are not FDA regulated–never have been–instead the labs are regulated under the Clinical Laboratory Improvement Amendments (CLIA) as overseen by the CMS. Laboratory developed tests are the kind your doctor orders, they are a service not a product and are not sold directly to patients. Labs develop new tests routinely and they do not apply to the FDA for approval. Despite this long history, the FDA has claimed that it has the right to regulate lab tests and they have merely chosen not to exercise this right for forty years. In 2015, Paul Clement the former US Solicitor General under George W. Bush and Laurence Tribe, considered by many to be the leading constitutional lawyer in the United States, wrote an article that rejected the FDA’s claims writing that the “FDA’s assertion of authority over laboratory-developed testing services is clearly foreclosed by the FDA’s own authorizing statute” and “by the broader statutory context.”
Despite lacking statutory authority, the FDA has continued to claim it is authorized to regulate laboratory tests. Indeed, a key failure in the pandemic happened when the FDA issued so-called “guidance documents” saying that any SARS-CoV-II test had to be pre-approved by the FDA. Thus, the FDA reversed the logic of emergency. In ordinary times, pre-approval was not necessary but when speed was of the essence it became necessary to get FDA pre-approval. The FDA’s pre-approval process slowed down testing in the United States and it wasn’t until after the FDA lifted its restrictions in March that tests from the big labs became available.
Clement and Tribe rejected the FDA claims of regulatory authority over laboratory developed tests on historical, statutory, and legal grounds but they also argued that letting the FDA regulate laboratory tests was a dangerous idea. In a remarkably prescient passage, Clement and Tribe (2015, p. 18) warned:
The FDA approval process is protracted and not designed for the rapid clearance of tests. Many clinical laboratories track world trends regarding infectious diseases ranging from SARS to H1N1 and Avian Influenza. In these fast-moving, life-or-death situations, awaiting the development of manufactured test kits and the completion of FDA’s clearance procedures could entail potentially catastrophic delays, with disastrous consequences for patient care.
Clement and Tribe nailed it. Catastrophic delays, with disastrous consequences for patient care is exactly what happened.
Addendum: See also my pre-pandemic piece on this issue, Our DNA, Our Selves.
Here is the NYT account, they sound both confused and confusing. How about “if you have had J&J, it is fine and probably preferable to get a further dose of Moderna or Pfizer”? Yet suddenly it is fine.
And it is the usual story — people have been doing this for months, and the FDA would not say it is terrible. Because they knew it wasn’t. But they wouldn’t say so. And now the status quo has shifted, and so everyone will treat it as fine, as if the supposed fears of yesterday never ever existed.
Maybe I should insult people more often?
What makes the FDAs failure to approve more rapid antigen tests even more galling is that the test being sold cheaply in the Amsterdam supermarket is the Flowflex, an American test made by Acon Labs in San Diego.
Well the FDA has finally approved the Acon test! Apparently it is good enough for the Germans and for US citizens. Hoorah! USA Today notes:
ACON expects to make 100 million tests per month by the end of this year. Production could double to 200 million monthly tests by February, according to the FDA.
…The United Kingdom and Germany have made significant purchases of home tests and widely distributed them to their residents to slow the spread of coronavirus. Such large government purchases allowed manufacturers to continue making tests even when demand softened as cases dropped.
The Biden administration will spend nearly $1.2 billion to purchase up to 187 million home tests from Abbott Laboratories and Celltrion Inc., company officials confirmed. The Department of Defense announced additional contracts totaling $647 million to buy 60 million kits from Abbott and three other testing vendors: OraSure Technologies, Quidel and Intrivio Holdings.
The FDA has authorized seven antigen-based tests that can be used at home without a prescription. The EU has authorized 21 tests beginning with the letter A (I am not sure all of these are authorized for home use but you get the idea.) Turtle slow. Still this is a big improvement.
Frankly, I think all the pressure from people like Michael Mina amplified by myself and others over 18 months and culminating in David Leonhartd’s NYTimes article Where Are the Tests? finally pushed them over the edge.
In July of 2020 I wrote in Frequent, Fast, and Cheap is Better than Sensitive:
A number of firms have developed cheap, paper-strip tests for coronavirus that report results at-home in about 15 minutes but they have yet to be approved for use by the FDA because the FDA appears to be demanding that all tests reach accuracy levels similar to the PCR test. This is another deadly FDA mistake.
…The PCR tests can discover virus at significantly lower concentration levels than the cheap tests but that extra sensitivity doesn’t matter much in practice. Why not? First, at the lowest levels that the PCR test can detect, the person tested probably isn’t infectious. The cheap test is better at telling whether you are infectious than whether you are infected but the former is what we need to know to open schools and workplaces.
It’s great that other people including the NYTimes are now understanding the problem. Here is the excellent David Leonhardt in Where are the Tests?
Other experts are also criticizing the Biden administration for its failure to expand rapid testing. Even as President Biden has followed a Covid policy much better aligned with scientific evidence than Donald Trump’s, Biden has not broken through some of the bureaucratic rigidity that has hampered the U.S. virus response.
In the case of rapid tests, the F.D.A. has loosened its rules somewhat over the past year, allowing the sale of some antigen tests (which often cost about $12 each). But drugstores, Amazon and other sellers have now largely run out of them. I tried to buy rapid tests this weekend and couldn’t find any.
The F.D.A.’s process for approving rapid tests is “onerous” and “inappropriate,” Daniel Oran and Dr. Eric Topol of Scripps Research wrote in Stat News.
For the most part, the F.D.A. still uses the same cumbersome process for approving Covid tests that it uses for high-tech medical devices. To survive that process, the rapid tests must demonstrate that they are nearly as sensitive as P.C.R. tests, which they are not.
But rapid tests do not need to be so sensitive to be effective, experts point out. P.C.R. tests often identify small amounts of the Covid virus in people who had been infected weeks earlier and are no longer contagious. Rapid tests can miss these cases while still identifying about 98 percent of cases in which a person is infectious, according to Dr. Michael Mina, a Harvard epidemiologist who has been advocating for more testing
Identifying anywhere close to 98 percent of infectious cases would sharply curb Covid’s spread. An analysis in the journal Science Advances found that test frequency matters more for reducing Covid cases than test sensitivity.
As I said on twitter what makes the FDA’s failure to approve more rapid antigen tests especially galling is that some of the tests being sold cheaply in Europe are American tests just ones not approved in the United States. If it’s good enough for the Germans it’s good enough for me!
Last week the FDA authorized and the CDC now recommends a third mRNA booster for the immunocomprimised. The CDC says:
Who Needs an Additional COVID-19 Vaccine?
Currently, CDC is recommending that moderately to severely immunocompromised people receive an additional dose. This includes people who have:
- Been receiving active cancer treatment for tumors or cancers of the blood
- Received an organ transplant and are taking medicine to suppress the immune system
- Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
- Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
- Advanced or untreated HIV infection
- Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response
That’s very reasonable but the headline is inaccurate because the CDC then goes on to say:
The FDA’s recent EUA amendment only applies to mRNA COVID-19 vaccines, as does CDC’s recommendation.
Emerging data have demonstrated that immunocompromised people who have low or no protection following two doses of mRNA COVID-19 vaccines may have an improved response after an additional dose of the same vaccine. There is not enough data at this time to determine whether immunocompromised people who received the Johnson & Johnson’s Janssen COVID-19 vaccine also have an improved antibody response following an additional dose of the same vaccine.
So if you got one dose of J&J and are immunocompromised then you can’t get a second dose. But if you got two doses of an mRNA (which is already more effective than one dose of J&J) and are immunocompromised then the CDC recommends a third dose. None of this makes any sense. The weasel words there ‘isn’t enough data to determine’ indicate a typical failure to think in Bayesian terms and use all the information available and a typical failure to think in terms of patient welfare and expected cost and benefits.
Notice also the illiberal default. Instead of saying ‘we don’t have data on the J&J vaccine and the immunocompromised so we are not at this time recommending or not recommending boosters but leaving this decision in the hands of patients and their physicians’ they say ‘we don’t have data and so we are forbidding patients and their physicians from making a decision using their own judgment.’
Hat tip: Pharmacist CB.
I have been highly critical of the FDA but in Australia the FDA is almost a model to be emulated. Steven Hamilton and Richard Holden do not mince words:
At the end of 2020, as vaccines were rolling out en masse in the Northern Hemisphere, the TGA [Therapeutic Goods Administration, AT] flatly refused to issue the emergency authorisations other regulators did. As a result, the TGA didn’t approve the Pfizer vaccine until January 25, more than six weeks after the US Food and Drug Administration (FDA), itself not exactly the poster child of expeditiousness.
Similarly, the TGA didn’t approve the AstraZeneca vaccine until February 16, almost seven weeks after the UK.
In case you’re wondering “what difference does six weeks make?“, think again. Were our rollout six weeks faster, the current Sydney outbreak would likely never have exploded, saving many lives and livelihoods. In the face of an exponentially spreading virus that has become twice as infectious, six weeks is an eternity. And, indeed, nothing has changed. The TGA approved the Moderna vaccine this week, eight months after the FDA.
It approved looser cold storage requirements for the Pfizer vaccine, which would allow the vaccine to be more widely distributed and reduce wastage, on April 8, six weeks after the FDA. And it approved the Pfizer vaccine for use by 12 to 15-year-olds on July 23, more than 10 weeks after the FDA.
And then there’s the TGA’s staggering decision not to approve in-home rapid tests over reliability concerns despite their widespread approval and use overseas.
Where’s the approval of the mix-and-match vaccine regimen, used to great effect in Canada, where AstraZeneca is combined with Pfizer to expand supply and increase efficacy? Where’s the guidance for those who’ve received two doses of AstraZeneca that they’ll be able to receive a Pfizer booster later?
In the aftermath of the pandemic, when almost all of us should be fully vaccinated,there will be ample opportunity to figure out exactly who is to blame for what.
But the slow, insular, and excessively cautious advice of our medical regulatory complex, which comprehensively failed to grasp the massive consequences of delay and inaction, must be right at the top of that list.
You might be tempted to argued that the TGA can afford to take its time since COVID hasn’t been as bad in Australia as in the United States but that would be to ignore the costs of the Australian lockdown.
Article 13 of the Universal Declaration of Human Rights states that
- Everyone has the right to freedom of movement and residence within the borders of each state.
- Everyone has the right to leave any country, including his own, and to return to his country.
Australia has now violated each and every clause of this universal human right and seemingly without much debate or objection. It is deeply troubling to see people prevented from leaving or entering their own country and soldiers in the street making sure people do not travel beyond a perimeter surrounding their homes. The costs of lockdown are very high and thus so is any delay in ending these unprecedented infringements on liberty.
The American Academy of Pediatrics has written a stunning letter to the FDA:
We understand that the FDA has recently worked with Pfizer and Moderna to double the number of children ages 5-11 years included in clinical trials of their COVID-19 vaccines. While we appreciate this prudent step to gather more safety data, we urge FDA to carefully consider the impact of this decision on the timeline for authorizing a vaccine for this age group. In our view, the rise of the Delta variant changes the risk-benefit analysis for authorizing vaccines in children. The FDA should strongly consider authorizing these vaccines for children ages 5-11 years based on data from the initial enrolled cohort, which are already available, while continuing to follow safety data from the expanded cohort in the post-market setting. This approach would not slow down the time to authorization of these critically needed vaccines in the 5–11-year age group.
In addition, as FDA continues to evaluate clinical trial requirements for children under 5 years, we similarly urge FDA to carefully consider the impact of its regulatory decisions on further delays in the availability of vaccines for this age group. Based on scientific data currently available on COVID-19 vaccines, as well as on 70 years of vaccinology knowledge in the pediatric population, the Academy believes that clinical trials in these children can be safely conducted with a 2-month safety follow-up for participants. Assuming that the 2-month safety data does not raise any new safety concerns and that immunogenicity data are supportive of use, we believe that this is sufficient for authorization in this and any other age group. Waiting on a 6-month follow-up will significantly hinder the ability to reduce the spread of the hyper infectious COVID-19 Delta variant among this age group, since it would add 4 additional months before an authorization decision can be considered. Based on the evidence from the over 340 million doses of COVID-19 doses administered to adults and adolescents aged 12-17,as well as among adults 18 and older, there is no biological plausibility for serious adverse immunological or inflammatory events to occur more than two months after COVID-19 vaccine administration.
In my many years of writing about the FDA, I can’t recall a single instance in which a major medical organization told the FDA to use a smaller trial and speed up the process because FDA delay was endangering the safety of their patients. Wow.
The invisible graveyard is invisible no more.
Here is just one bit from a superb post on the FDA by psychiatrist Scott Alexander at Astral Codex Ten.
I worry that people are going to come away from this with some conclusion like “wow, the FDA seemed really unprepared to handle COVID.” No. It’s not that specific. Every single thing the FDA does is like this. Every single hour of every single day the FDA does things exactly this stupid and destructive, and the only reason you never hear about the others is because they’re about some disease with a name like Schmoe’s Syndrome and a few hundred cases nationwide instead of something big and media-worthy like coronavirus. I am a doctor and sometimes I have to deal with the Schmoe’s Syndromes of the world and every [email protected]$king time there is some story about the FDA doing something exactly this awful and counterproductive.
A while back I learned about Infant Short Bowel Syndrome, a rare condition with only a few hundred cases nationwide. Babies cannot digest food effectively, but you can save their lives by using an IV line to direct nutrients directly into their veins. But you need to use the right nutrient fluid. The FDA approved an early draft of the nutrient fluid, but it didn’t have enough fish oil, which is necessary for development, so a lot of the babies still died or ended up with permanent neurological damage. Around the late 90s/early 00s, researchers figured out what was going on and recommended adding fish oil to the IV fluid. The FDA responded that they had only approved the non-fish-oil version, it would take them a while to approve the new version, and until they did that adding fish oil was illegal. A bunch of babies kept dying and getting permanent neurological damage, and everyone knew exactly how to stop it, but if anyone did the FDA would take away their licenses and shut them down. Around 2010, Boston Children’s Hospital found some loophole that let them add fish oil to their nutrient fluid on site, and infants with short bowel syndrome at that one hospital stopped dying or ending up permanently disabled, and the FDA grudgingly agreed to permit it but banned them from distributing their formulation or letting it cross state lines – so for a while if you wanted your baby not to die you had to have them spend their infancy in one specific hospital in Massachusetts. Around 2015 the FDA said that if your doctor applied for a special exemption, they would let you import the correct nutritional fluid from Europe (where, lacking the FDA, they had just added fish oil to the fluid as soon as researchers discovered it was necessary), but you were only able to apply after your baby had already sustained serious damage, and the FDA might just say no. Finally in 2018 the FDA got around to approving the corrected nutritional fluid and now babies with short bowel syndrome do fine, after twenty years of easily preventable state-mandated deaths. And it’s not just this and coronavirus, I CANNOT STRESS ENOUGH HOW TYPICAL THIS IS OF EVERYTHING THE FDA DOES ALL THE TIME.
Read the whole thing! I actually had to read it in several sessions, it’s not that long but bouts of anger interspersed with moments of laughter made me have to put it down momentarily to recover. There is a lot more in the post on reforms.
Addendum: Scott updates the infant fish oil story and provides much more detail. He got some things wrong and the FDA as an agency ends up looking better but the broad outline about the FDA system looks right. I am leaving the post up for posterity but this specific part isn’t correct.
Here is the audio, video, and transcript, I found it a very substantive and also illuminating episode. Carpenter is very, very smart and also very well-informed historically. Here is part of the summary:
Daniel Carpenter is one of the world’s leading experts on regulation and the foremost expert on the US Food and Drug Administration. A professor of Government at Harvard University, he’s conducted extensive research on regulation and government organizations, as well as on the development of political institutions in the United States. His latest book Democracy by Petition: Popular Politics in Transformation, details the crucial role petitions played in expanding the franchise and shaping modern America.
Here is an excerpt from the non-FDA section, much of which focuses on (non-FDA) regulation:
COWEN: What kinds of records should the Postal Service keep about itself?
CARPENTER: [laughs] Great question. There’s a whole set of things that they don’t since the Griswold decision and since the First Amendment decisions. They don’t keep as much records of what goes through the mail. They can’t prohibit things like pornography, contraception.
I guess it depends on what you mean by “itself.” I would start with the idea that basic privacy restrictions, which governed the postal system as much through norm as by law in the 19th century and early 20th century, should govern the system.
It’s a crime if I were to walk past your mailbox and open your letter. I’m committing a federal crime, but there were also norms that seals were not to be broken, things like that. I do think whichever way the Postal Service goes — and it’s quite possible that you could imagine an electronic platform for the US postal system — I think basic privacy restrictions have to be guaranteed.
Actually, in some respects, I think we need to know a fair amount about what postal workers do without, say, calling for Amazon tracking. But if we think that postal workers are misplacing ballots or not providing birth control pills or something like that, then we should probably have some way of picking up on that kind of nefarious behavior.
In the FDA section I got mad at him, the first (but not last?) time that has happened in a CWT, do read or listen to the whole section, the two of us really had at it! Here is a tiny sliver from it:
COWEN: But shouldn’t there be a button within the FDA that can be pushed, where the FDA goes into a kind of wartime mode?
I don’t want to misrepresent Carpenter by an ill-chosen excerpt, so please do digest his full set of replies. Recommended.
NYTimes: The Covid-19 pandemic has forced the Food and Drug Administration to postpone hundreds of drug company inspections, creating an enormous backlog that is delaying new drug approvals and leading the industry to warn of impending shortages of existing medicines.
…In an interview, F.D.A. officials said they sharply curtailed the inspections to protect their investigators, following guidelines from the Centers for Disease Control and Prevention, which discouraged federal employees from travel during the pandemic.
But some people in both industry and public health communities say that federal drug inspections are essential, and that the agency should bypass travel restrictions by taking precautions, including wearing proper personal protective equipment.
…In interviews, F.D.A. officials denied that the dramatic drop in inspections has slowed drug approvals. But a number of drug companies, including Spectrum Pharmaceuticals, Biocon Biologics and Bristol Myers Squibb, has issued statements noting deferred F.D.A. action because of the agency’s inability to conduct inspections.
In October, Spectrum announced that the F.D.A. had deferred action on its application for Rolontis, a treatment for cancer patients who have a very low number of certain white blood cells, because it could not inspect the manufacturing plant the company uses in South Korea.
In late December, Biocon Biologics notified shareholders that the F.D.A. deferred action on its joint application with Mylan for a proposed biosimilar to Avastin, a cancer drug.
Bristol Myers Squibb announced in November that the F.D.A. would miss its November deadline for taking action on a lymphoma treatment, lisocabtagene maraleucel because it could not inspect a third-party Texas manufacturing plant. The agency eventually did complete its inspection and approved the drug last month.
Grocery store workers are working, meat packers are working, hell bars and restaurants are open in many parts of the country but FDA inspectors aren’t inspecting. It boggles the mind.
Let’s review. The FDA prevented private firms from offering SARS-Cov2 tests in the crucial early weeks of the pandemic, delayed the approval of vaccines, took weeks to arrange meetings to approve vaccines even as thousands died daily, failed to approve the AstraZeneca vaccine, failed to quickly approve rapid antigen tests, and failed to perform inspections necessary to keep pharmaceutical supply lines open.
I am a long-time critic of the FDA and frankly I am stunned at the devastation.
After the FDA advisory committee voted in favor of Pfizer’s EUA last Thursday–as almost everyone thought they would–the FDA had difficulty finishing the paperwork. The NYTimes reported:
People familiar with the F.D.A.’s situation say that regulators are now racing to complete a fact sheet, information for physicians and other required documents that go with the authorization.
The paperwork delay meant that the FDA was going to wait to issue the EUA until Monday. That’s when Trump called the FDA “a big, old, slow turtle” and yelled at Hahn to “Stop playing games and start saving lives!!!.” The FDA then sped up and issued the EUA on Friday. As a result, the first tranche of vaccines are being delivered today.
The advisory committee for the Moderna vaccine meets this coming Thursday. Here’s a polite request of the FDA–please have the fact sheet, information for physicians and other required documents ready to go. Thanks.
P.S. We would also be really grateful and, you know, it might save some lives if you allowed Moderna to start shipping now so the vaccine is on-site and ready to go on Friday. Please give it some thought and thanks again for your kind consideration. It’s been very stressful seeing thousands of people dying every day.
Two to three thousand people a day are dying from COVID. Thus anything that delays rolling out a vaccine has a very high cost in human lives. People want to deny this, perhaps because it is so horrifying. I get a lot of pushback when I say that FDA delay is deadly. Let’s dispense with a few objections. It is true, of course, that the people who are dying today can’t literally be saved by a vaccine today but they could have been saved had they been vaccinated four or five weeks ago and similarly projecting forward.
Another response that many smart people tell me is that a vaccine can’t be rolled out immediately so even under the best scenarios you couldn’t save that many people immediately. That’s true but irrelevant. Since a lot of people are getting this wrong, I want to show this in a simple model using pictures. Red is for deaths. Green is for life. Suppose two thousand people are dying from COVID a day as in panel 1. Let’s for the sake of the simple model assume that you could deliver a vaccine to everyone on Day 1. You would then save 2000 lives a day going forward for however long the pandemic would have lasted as shown in panel 2. If you delay by one day then two thousand people die who would have lived without the delay, as shown in panel 3. Pretty obvious so far.
Now assume that the vaccine can’t roll out to everyone immediately. For the sake of this simple model let’s assume that on day one you can only vaccinate half the population. By doing so you save 1000 lives on day 1 and 2000 lives every day thereafter for the length of the pandemic. That’s the fourth panel. Now suppose we delay the vaccine rollout by one day. 2000 people die on Day 1 but you save 1000 on Day 2 and 2000 on Day 3 and every day thereafter for the length of the pandemic. How many people were killed by the delay? Compare the 4th and 5th panels. 2000 exactly as before! The slow ramp up doesn’t change the number of deaths caused by delay it just spreads them out over different days. You can adjust the ramp so that it occurs over 10 days or 30 days. Doesn’t change much on the delay margin unless you delay for so long that the pandemic is close to being over.
What could matter is if delay increases the speed at which you can ramp up. I doubt that this is true. We were ready to go with millions of doses in late October (guess why?). (In fact we had a vaccine in January and millions of doses around March-April.) We won’t really be better prepared tomorrow than we are today. It’s learning by doing that matters. See the point Tyler made earlier about economic time versus calendar time.
As Tyler noted, this is hardly the final analysis but many people are not even conceptualizing the problem correctly and this is a good place to begin.
