> we basically have NO DATA on single dose schedules for Moderna/Pfizer vaccines I wonder if anything can be deduced given knowledge of the mechanisms these vaccines use compared to other vaccines against other viruses. I know there are vaccines like for HEP-A that confer immunity for at least 10 years given a single shot, and a 20+ years of immunity if a booster is given in six months. It appears that the FDA doesn't want to offer any information outside of the studies. This cut in half the number of people who can be protected during this winter's covid season.
