Today, August 23, 2021, the United States Food and Drug Administration has announced the full approval of the Pfizer/BioNTech vaccine against SARS-CoV2, the virus that causes COVID-19, for people aged 16 and up. People aged 12-15 are still being immunized under the emergency use authorization. It is also expected that, in the coming weeks, Pfizer will apply for emergency use authorization for children aged 5-11. Research is ongoing on children 6 months-4 years. Also, most adults will become eligible for a third dose to boost immunity, given from 8-12 months after the second dose.
Meanwhile, both Moderna and Johnson & Johnson, the other two vaccines available under emergency use authorization in the US, are continuing their research and applications to expand their age ranges and gain full approval, too.
It’s possible that, for some people who have been reluctant to be vaccinated, the full approval of the Pfizer vaccine might be enough to convince them to receive it. The US has seen many more shots being administered in recent weeks as the delta variant has surged and people realize that nearly all the people being hospitalized and dying are those who were unvaccinated. Unfortunately, it takes several weeks to build immunity from the vaccine so the delta surge will likely continue into the coming months.
The other expected impact of the full approval of the Pfizer vaccine is that more employers may mandate that their workers be immunized before returning to in-person work and more businesses may require immunization (or alternatively a recent negative test) for their patrons.
As regular readers may remember, my spouse B, daughter T, and I are all part of the Pfizer Phase III trial for the vaccine. B and T were lucky enough to receive the actual vaccine in August 2020 while I wound up being in the placebo group. When the vaccine received emergency use authorization, the study was unmasked so that people in the placebo group could receive the vaccine, which I did in February 2021. I will continue to be followed as part of the original study through August 2022. B and T, meanwhile, have entered into the third dose phase of the study. They will be providing data for the continued study of how much immunity boost occurs with the third dose and how long it lasts.
I continue to mourn for all those who are suffering as a result of the pandemic. Please, everyone, listen to the public health specialists in your area, receive the vaccine as soon as it is available to you, and mask, distance, and wash hands as directed. Please, do everything you can to protect the health of yourself, your loved ones, and your community.
