Bill Emmott, former editor-in-chief of The Economist and now co-director of the Global Commission for Post-Pandemic Policy, talks to Alex Tabarrok, Professor of Economics at George Mason University and co-author of the blog Marginal Revolution, on lessons learned from the pandemic so far, and what lies ahead.
Self-recommending. I’d say it’s a very good interview but there was no question that I was outclassed by Bill Emmott’s zoom background, live from Dublin. Many thanks to the ever-excellent The Browser for hosting.
A lot of new information has dropped recently about the efficacy of First Doses First.
First, as I mentioned yesterday, we now have epidemiologists and vaccine researchers saying that for people previously infected with COVID a second dose is not necessary and may be “overkill.” Given how many people have had COVID, this increases the net benefit to First Doses First for everyone significantly.
Second, an important new study verifies that for the AZ vaccine a longer delay for the second dose is better because it generates a more powerful immune response (picture from the FT). This is a common finding for vaccines. The authors write:
ChAdOx1 nCoV-19 vaccination programmes aimed at vaccinating a large proportion of the population with a single dose, with a second dose given after a 3 month period is an effective strategy for reducing disease, and may be the optimal for rollout of a pandemic vaccine when supplies are limited in the short term.
In addition “Analyses of PCR positive swabs in UK population suggests vaccine may have substantial effect on transmission of the virus with 67% reduction in positive swabs among those vaccinated.” In other words, the vaccine cuts transmission risk.
As I have said before “the US failure to authorize the AstraZeneca vaccine in the midst of a pandemic when thousands are dying daily and a factory in Baltimore is warmed up and ready to run is a tragedy and dereliction of duty of epic proportions.”
Third, the New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG), a scientific advisory group to the British government, recently considered the risks of immune escape from the delayed second dose strategy and concluded that although the risk is real it is likely small, especially in comparison to other sources of immune escape such as therapeutics and natural infection. Moreover, the risk is outweighed by the measurable benefits of getting more does out quickly.
It is not currently possible to quantify the probability of emergence of vaccine resistance as a result of the delayed second dose, but it is likely to be small.The UK currently has more than 1,000 COVID-19 related deaths each day and has limited supplies of vaccine. In the current UK circumstances the unquantifiable but likely small probability of the delayed second dose generating a vaccine escape mutant must be weighed against the measurable benefits of doubling the speed with which the most vulnerable can be given vaccine-induced protection.
..a single dose of vaccine does not generate a new/novel risk. Given what we have observed recently with the variants B.1.1.7 and B1.351, it is a realistic possibility that over time immune escape variants will emerge, most likely driven by increasing population immunity following natural infection.
The 4 UK Chief Medical Officers agree with the JCVI that at this stage of the pandemic prioritising the first doses of vaccine for as many people as possible on the priority list will protect the greatest number of at risk people overall in the shortest possible time and will have the greatest impact on reducing mortality, severe disease and hospitalisations and in protecting the NHS and equivalent health services.
Fifth, the US public health experts are beginning to come around to the economic point of view. Consider Experts tout delaying 2nd COVID vaccine dose as US deaths mount which notes:
“The maximum public health benefit would come from giving a single dose to as many people as possible, and following up with a second dose when supply improves,” said Neal Halsey, MD, of Johns Hopkins University, in an interview. Halsey and Stanley Plotkin, MD, co-authored a letter in Clinical Infectious Diseases last week explaining how delaying a second dose of vaccine would accelerate the US vaccine rollout.
Halsey said data from both companies show the first dose of the vaccine offers significant protection against COVID-19 in the short term, for at least 1 to 3 months after injection. He also said he and Plotkin believe this was the most beneficial public health strategy even before the arrival of new variants of the virus was discovered.
“There are a number of examples of changing [vaccination] course because ACIP takes into account public health impact,” Halsey said. “We asked the ACIP to review in depth this strategy to give one dose as rapidly as possible. Such a meeting should be scheduled as soon as possible.”
The University of Minnesota’s Michael Osterholm, PhD, MPH, said yesterday on “Meet the Press” that he believes the United States has to change direction on vaccine strategy in light of the possibility of a surge of new infections coming from variant strains.
I believe that the US will go to First Doses First. The only question is will we go to First Doses First soon, when it can still help, or will we be forced to do it later in an act of desperation and agony.
The barriers are breaking. Step by step we move closer to First Doses First. New results from a small-scale study suggest that people who have had COVID have strong reactions to the first dose and may not need the second dose.
NYTimes: Based on these results, the researchers say, people who have had Covid-19 may need only one shot.
“I think one vaccination should be sufficient,” said Florian Krammer, a virologist at the Icahn School of Medicine at Mount Sinai and an author on the study. “This would also spare individuals from unnecessary pain when getting the second dose and it would free up additional vaccine doses.”
…People who have had Covid seem to be “reacting to the first dose as if it was a second dose,” said Akiko Iwasaki, an immunologist at the Yale School of Medicine. So one dose is probably “more than enough,” she said.
A study published earlier this month reported that surviving a natural infection provided 83 percent protection from getting infected again over the course of five months. “Giving two doses on top of that appears to be maybe overkill,” she added.
So for the 25 million to 100 million Americans who have already been infected by COVID it may be better for them personally to delay the second dose. In short, a significant fraction of second doses have little to no value. This (unsurprising) finding means that First Doses First is an even better strategy even if we can’t condition doses on previous infection.
Most important, First Doses First gets more people significant immunity faster which is good for the vaccinated and also drives down R which is good for society as a whole, even the unvaccinated.
The Biden administration has been more pro-active than the Trump administration on tests and vaccination and has already made some goods calls on getting more doses out faster. I hope they continue to be bold. We need quick, bold, and decisive action.
NYTimes: Federal regulators could decide within a few weeks whether to allow Moderna, the Massachusetts biotech company that developed one of the two federally authorized Covid-19 vaccines, to increase the number of doses in its vials — which could accelerate the nation’s vaccination rate.
Moderna is hoping to raise the number of doses in its vials to as many as 15 from the current 10 doses, a potential 50 percent increase. The proposal reflects the fact that the company has been ramping up production of its vaccine to the point where the final manufacturing stage, when it is bottled, capped and labeled, has emerged as a roadblock to expanding its distribution.
The FDA will decide in a few weeks???! That is not quick, bold, and decisive action.
Thousands of people have already died over a few weeks delay–multiple times. It’s true that there are tradeoffs but the FDA has no special knowledge or ability to navigate those tradeoffs. Let Moderna make the decision in consultation with vaccinators on the front lines.
Philadelphia health officials say they’re no longer providing vaccines to a 9-month-old start-up that has begun inoculating thousands of city residents, citing the group’s quiet switch to a for-profit entity.
“We have recently been made aware of a change in Philly Fighting COVID’s corporate status that took place without our knowledge, from nonprofit to for-profit,” said Health Department spokesperson Jim Garrow.
The move comes days after WHYY News and Billy Penn reported that Philly Fighting COVID had established a for-profit arm, and that when the group pivoted from providing community testing to performing vaccinations, it left several partner organizations in the lurch.

Illicit sales of fake negative Covid-19 test results are becoming more widespread as criminals look to profit from travel restrictions imposed during the pandemic, according to Europol.
The EU’s law enforcement agency on Monday reported an increase in cases of fraudulent Covid-19 test certificates being sold to travelers. It comes as an increasing number of countries in the European Union and beyond oblige travelers to present a negative coronavirus test in order to be allowed entry, when travelling from a high-risk area.
In its latest Early Warning Notification, which Europol issues to alert EU member states of new or increasingly prevalent forms of criminal activity, the agency said the latest case of this crime had been detected in Luton Airport in the U.K., where a man was arrested trying to sell false coronavirus test results. Elsewhere in the U.K., fraudsters were caught selling bogus Covid-19 test documents for £100 ($137).
There had also been earlier reports of similar activity in other European countries.
A forgery ring at Charles de Gaulle Airport in Paris, for example, was “dismantled” after being found selling forged negative test results to passengers, Europol said. The amount charged for the fake test documents ranged between 150-300 euros ($181-$363).
Another fraudster was apprehended in Spain for selling false negative test certificates on the internet for 40 euros, and in the Netherlands, scammers were discovered selling fake negative test results for 50-60 euros through messaging apps.

Here is an interview with Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine and the lead developer of a COVID vaccine being produced in India. He thinks the AstraZeneca vaccine should be approved immediately, as I have long argued.
President Biden himself announced Tuesday that we’re going to have maybe enough additional doses of the mRNA vaccines to fully vaccinate 300 million Americans by the end of summer or fall.
I’m saying, “Well, no, that’s that’s not gonna work.” Telling us “by the fall” is like telling us “when the glaciers are gonna come back down from Quebec.” I mean, that’s not adequate.
We’re going to have to figure out a way to vaccinate the American people by late spring. That’s a tall order. To beat back the virus we need to give two doses to three-quarters of the population, to 246 million Americans. That’s half a billion immunizations. To get there, we’d need a rate of immunizations two or three times higher than what’s proposed.
….We need vaccinations now.
..things have been slowed down with the AstraZeneca-Oxford adenovirus vaccine. My understanding is that the FDA insisted that they conduct a full-scale Phase Three trial in the U.S., and we won’t have results for that until April. Meanwhile, the European Medicines Agency, the EMA, is going to make a ruling on the AstraZeneca Oxford vaccine on Friday based on studies done in Europe and also probably on data from Brazil and South Africa. [The EMA authorized, AT].
Those are large, reliable studies?
Yeah….Because of these new variants, there’s great urgency here in the U.S. So I’m saying that sometimes we have to do things that take us out of our comfort zone in order to save lives. That means, rather than focusing only on the new study that we’re doing in the U.S., we also look at the dossier presented to the EMA.
As a regulatory agency the EMA is up there with our U.S. FDA. They’re the two best regulatory agencies in the world. So if they sign off, I think we should say, “Look, let’s do it. Let’s use that vaccine.”
We’ve already bought 300 million doses of the AstraZeneca-Oxford vaccine. We’ve paid for it — over a billion dollars — so let’s use it.
…And there’s also the recombinant protein vaccine our lab has developed at Baylor College of Medicine and Texas Children’s Hospital. In India they’re scaling that up to a billion doses. Nobody from the White House has approached us to say, “Hey, Peter, what can we do to bring that vaccine in.”
There seem to be blinders: All they can see is getting the mRNA vaccines. I don’t quite know what’s driving that. We have to figure out a way to bring the other ones on board.
And soon! We’re in the eye of the hurricane.

EconLib: Experts in the UK have looked at the AstraZenaca vaccine and found it to be safe and effective. And yet Americans are still not allowed to use the product. So if paternalism is not the actual motive, why do progressives insist that Americans must not be allowed to buy products not approved by the FDA? What is the actual motive?
The answer is nationalism. The experts who studied the AstraZenaca vaccine were not American experts, they were British experts. Can this form of prejudice be justified on scientific grounds? Obviously not. There has been no double blind, controlled study of comparative expert skill at evaluating vaccines. We have no way of knowing whether the UK decision is wiser than the FDA decision. Instead, the legal prohibition is being done on nationalistic grounds. We are told to blindly accept the incompetence of British experts, without any proof. (And even if you believed there was solid evidence that one country’s experts were better than another, it would not explain why each developed countries relies on their own experts. They can’t all be best!)
These debates always end up being like a game of whack-a-mole. Shoot down one argument and regulation proponents will simply put forth another. Their minds are made up. You say people shouldn’t be allowed to take a vaccine unless experts find it to be safe and effective? OK, the UK experts did just that. You say that only the opinion of US experts counts because our experts are clearly the best? Really, where is the scientific study that shows that our experts are the best? I thought you said we needed to “trust the scientists”? Now you are saying we must trust the nationalists?
…what’s wrong with the following three-part system of regulation as a compromise solution:
1. FDA approved drugs can be consumed by anyone in America.
2. Drugs approved by any of the top 20 advanced countries (but not the FDA) can be consumed by anyone willing to sign a consent form indicating that they understand the FDA has not approved this product. I’ll sign for AstraZeneca. (The US government puts together a list of 20 reputable countries.)
3. Drugs approved by none of the top 20 developed economies will still be banned.
This is what regulation would look like if paternalism actually were the motivating factor. But it’s not. It’s Trump-style nationalism that motivates progressives to insist that only FDA approved drugs can be sold in America. They may look down their noses at Trump, but they implicitly share his nationalism.
I agree, of course, and have long supported Pharmaceutical Reciprocity.
We called it the invisible graveyard, the place they buried people killed by FDA delay. Back then only a few of us–mostly libertarians long practiced in seeing the invisible hand–could see the invisible graveyard. Normal people looked at us oddly and quickly ran away when we frantically pointed to the dead. “There! there! Can’t you see the bodies?” Now, however, the veil has been lifted and even normal people see.
Here is Ezra Klein writing in the NYTimes:
The problem here is the Food and Drug Administration. They have been disastrously slow in approving these tests and have held them to a standard more appropriate to doctor’s offices than home testing. “The F.D.A. needs to catch up to the science,” Mina said, frustration evident in his voice. “They are inadvertently killing people by not following the science.” On my podcast, I asked Vivek Murthy, President Biden’s nominee for surgeon general, whether the F.D.A. had been too cautious. “I do think we’ve been too conservative,” he told me. Murthy went on to argue that there’s a difference between the diagnostic testing doctors do and the surveillance testing the public could do and that the F.D.A. had failed to appreciate the difference. Speeding the F.D.A. on this issue will be an early, and crucial, test for the Biden administration. In this case, Democrats need to deregulate.
Even back in December when I was tweeting from the rooftops things like:
Your daily reminder that 14,696 people have died from COVID in the United States since Pfizer applied for an EUA from the FDA.
people argued that I was exaggerating the simple math of FDA delay. Today, however, the reality of deadly delay is almost conventional wisdom. Here’s Klein again:
The new strains spread quickly. The speed of our countermeasures will decide our fate. What feel like reasonable delays in our normal experience of time — a few weeks here for Congress to debate a bill, a few weeks there for the F.D.A. to hold meetings — could lead to the kind of explosive infections that overwhelm our hospitals and fill our morgues.
The contentiousness is much worse in Europe, where zero- and negative-sum thinking is the order of the day. That is the theme of my latest Bloomberg column, here is one bit:
In most of Europe, it’s hard to see much good news. It’s one thing not to have a vaccine. It’s far worse to turn on television or go on the internet and see people in other countries being vaccinated as their pandemics recede. Most of Europe will not be making significant vaccination progress until April, and even then shortages may remain.
At stake is the very legitimacy of the EU. Most of the vaccination contracts were handled at the EU level, although Germany sidestepped the agreed-upon procedures and cut some deals. If the EU fails at the most significant crisis in a generation, it may not maintain much legitimacy.
When people judge how painful an experience was, they often place a high value on first and last impressions. The last impressions of the U.S. and U.K. will be pretty positive. Most of the U.S. pandemic will be over by July, even under a subpar vaccination schedule. And it may turn out that mRNA vaccines are more protective against the new strains of Covid than any alternatives….
Many European countries may end up with fewer deaths per capita than the U.S. But at the end of the pandemic many Europeans may feel like their leaders failed them, that they suffered lockdowns for many months but received little in return. Right now vaccine politics is all about momentum, and so far only a few countries have it.
From an email to Fairfax County teachers:
Due to a decrease in vaccine allocation, we are temporarily reducing appointment availability over the coming weeks. Vaccine supply is fluid across the country, and we are matching currently scheduled appointments to anticipated inventory.
We are pleased to share that more than 22,000 Fairfax County Public Schools teachers and employees have already been able to schedule their first shot. At this time we are honoring those who have current appointments. Should our vaccine supply not be sufficiently replenished, we will suspend initial appointments (first doses) for eligible individuals in 1b and prioritize those who require their second vaccine dose in the weeks to come.
It’s really quite stunning when you think about it.

A contentious requirement for Japan-specific trials has delayed the rollout of Covid-19 vaccines in Asia’s largest advanced economy and threatened the Tokyo Olympics.
Small clinical trials that demonstrate the vaccines generate a similar level of antibodies when used in Japan are the main outstanding condition for approval of the jabs from BioNTech/Pfizer and several other companies.
Japan’s demand for proof that safety and efficacy do not differ in the country means that it will not start vaccinations until the end of February — three months after the earliest rollouts and fewer than five months before the delayed Tokyo Olympics are due to start.
As of tomorrow, hospitals in Virginia will no longer be able to administer COVID-19 vaccines. Thousands of elderly people are having their vaccine appointments canceled. From now on, all COVID-19 vaccines will go to the local health departments and none directly to hospitals.
Virginia Hospital Center had been running clinics all day every day to give people the vaccine. Appointments there for all 1st dose vaccines have been canceled because the hospital will no longer be able to get the vaccines.
Northam’s health department has also forbidden people from crossing county lines to get the vaccine. If the county next to you has an abundance of the vaccine, you can’t get it. Only residents of that county may get their vaccine.
These new rules will result in many people either having their vaccination appointment canceled or delayed for months. Currently, 7.5 million people in Virginia, Maryland, and DC qualify to get the vaccine, if only they had access to it. The new rules limit the options citizens have for getting the shot. Everyone MUST go through their local health department to be vaccinated. That means in a county such as Loudoun, with a population of over 420,000, and two health department locations to receive the vaccine, will continue to inoculate 400 to 900 people a day. There are no other options. The Loudoun health department has said they are trying to open a third location for vaccinations (possibly at Dulles Town Center) but that could take months. If Loudoun continues at its current pace it will take well over a year for the local health department to inoculate all those who want vaccines. If Loudoun hospitals were allowed to open clinics for vaccines, many more people could be inoculated every day but the Northam administration will not permit it.

The Miami Heat are bringing back some fans, with help from some dogs.
The Heat will use coronavirus-sniffing dogs at AmericanAirlines Arena to screen fans who want to attend their games. They’ve been working on the plan for months, and the highly trained dogs have been in place for some games this season in which the team has allowed a handful of guests — mostly friends and family of players and staff.
Starting this week, a limited number of ticket holders will be in the seats as well, provided they get past the dogs first.
“If you think about it, detection dogs are not new,” said Matthew Jafarian, the Heat’s executive vice president for business strategy. “You’ve seen them in airports, they’ve been used in mission-critical situations by the police and the military. We’ve used them at the arena for years to detect explosives.”
Here is the full story, the first game under this regime is Thursday.
For all of its achievements, we still do not know if New Zealand will have ended up doing a good job against Covid-19:
New Zealand’s “go hard, go early” strategy to combat Covid-19 attracted global praise and eliminated local transmission of the virus. But the country’s slow rollout of vaccines is putting people at unnecessary risk and threatens to delay its economic recovery, critics warned.
Wellington plans to start vaccinating frontline workers in April and the general public from July under a cautious strategy that avoids the emergency authorisation of vaccines pursued by crisis-stricken nations such as the US and UK.
And note this:
There are at least 19 cases of the coronavirus variants first identified in the UK or South Africa in managed quarantine facilities in New Zealand for overseas arrivals, according to government data.
Mr Hipkins said there was “absolutely no complacency” in the government’s response.
Here is the full FT story.
