As compared to the flu shot? The one that I’ve been given for free in every school and workplace I’ve attended in the past twenty years?
Logistically, yearly shots are nbd. Maybe we should make flu shots mandatory for education just like the MMR shot, given the number of kids killed by the flu every year.
