Trypanophobia or How to Alleviate Vaccine Hesitancy

A significant share of vaccine hesitancy is driven by fear of needles, trypanophobia. Adults don’t like to admit a fear of needles and less so that they would avoid a vaccine for fear of a needle. But trypanophobia is common and does reduce flu immunizations:

Avoidance of influenza vaccination because of needle fear occurred in 16% of adult patients, 27% of hospital employees, 18% of workers at long‐term care facilities, and 8% of healthcare workers at hospitals. Needle fear was common when undergoing venipuncture, blood donation, and in those with chronic conditions requiring injection.

Aside from fear of the needle, I think there is also a perception that needles are “serious medicine” and thus anything that comes in needle form must be serious or dangerous. In fact, vaccines are safer than many commonly used drugs that are taken orally.

Needle hesitancy is bad for the hesitant who don’t get protection from COVID and bad for everyone else who are further subject to transmission from unvaccinated carriers.

The best way to alleviate needle hesitancy is to get rid of the needle. Operation Warp Speed made smart investments in a fairly widely range of vaccines (we advised going wider) including a pill vaccine from VaxArt. The VaxArt vaccine has completed a Phase I trial with modest results and is moving into Phase II. Nasal vaccines are in development. The RadVac open science vaccine, for example, is a nasal vaccine available to anyone with a scientific bent willing to give an unapproved vaccine a try. CodaGenix has a nasal vaccine in Phase I trials as does Altimmune.

Aside from ease of delivery, a COVID nasal or oral vaccine may also be better than intramuscular injection because it stimulates the immune system at the first point of viral attack, the mucosal tissues in the nose, mouth, lungs and digestive tract. In addition, the mucosal immune system has some unique elements so you get a potentially stronger immune response more capable of neutralizing the virus quickly.

Operation Warp Speed investments generated trillions in value for billions in cost, a few additional smart investments in accelerating nasal and oral vaccines could pay off highly in mopping up vaccine hesitancy and moving us more quickly to herd immunity. We could even do a human challenge trial with nasal vaccine v. intramusucalar injection. Oral and nasal vaccines will also be great for kids and for booster shots.

Even at this late stage we are spending trillions on stimulus/relief and not enough on investment, especially on highly successful investment in vaccines.

Addendum: I know it probably won’t help but fyi, it’s a painless shot. Nothing to fear! Get a superpower and a donut afterwards. It will be memorable.
