Last week, B, T, and I each had our initial visit for the Pfizer/BioNTech vaccine trial for COVID-19. There was a lengthy informed consent document, medical history and physical exam, COVID test, blood draw, and injection with either the trial vaccine or placebo. Two of us had some mild side effects and one of us did not, so we are surmising that one of us received the placebo, but the study is triple-blind (participant, care provider, investigator) so we don’t know for sure if that is the case.
The Pfizer/BioNTech vaccine is a messenger RNA vaccine; this type of vaccine has not previously been approved for widespread use. It works by enclosing a strip of messenger RNA in a lipid shell. When it gets into cells, it manufactures the spike protein that the SARS-CoV-2 has on its exterior, so that the body recognizes it and makes antibodies and T-cells to combat it.
The phase I data looks promising, so I hope that this vaccine will be found effective. RNA vaccines are able to be manufactured quickly, which will be a plus if they are approved for use. I am hoping that a number of vaccines will be able to complete Phase III trials and earn approval, so that we can get as many people around the world vaccinated as quickly as possible. It’s the only way to gain herd immunity without a horrifying level of illness and loss.
The Pfizer/BioNTech trial is expected to finish its primary collection of data needed for approval in mid-April 2021, although the trial will continue to follow participants through November 2022 to see how well antibodies and T-cells persist.
Science takes time and the COVID vaccine is being developed at a blindingly fast rate in terms of past vaccine development. Remember that we are still looking at months before approval, not weeks. Even when one or more vaccines are approved, people will need to keep up with distancing, masks, sanitizing, etc. to keep the disease at bay while vaccination production and distribution campaigns occur.
Please, everyone, do your part to keep yourself, your family, and your neighbors as safe as possible, while vaccines and effective treatments are developed. I’ll post more information about our trial as time goes on.
