Not sure I agree that following the scientists favors the second option. Many scientists worry that the UK approach will increase the odds of generating vaccine resistant variants by putting out lots of people with low levels of antibodies which would favor escape mutations.Â
I think the first approach is the best. Remember, mRNA vaccines are a completely new type of vaccine, and both were designed to be given in two shots. The adenovirus vaccines may be another story but the science on them is murky. They are a slightly mature technology as well.
To wit, I am aware of two physicians who caught covid after getting one dose of the vaccine (one was Pfizer, not sure on the other). One about a week later, another two weeks. 95% efficacy was after two doses, and then in a controlled trial.
