Erosion against serious disease, hospitalization and death. with this omicron variant we see boosters aren't a guarantee that you are not going to get infected with it and it's just a transient benefit, maybe 10 or 12 weeks after the booster the levels fall down. i don't think that boosting healthy people to prevent mild illness makes sense with these first generation vaccines. i think we need to focus on getting first and second doses, i'm going to work at the hospital tomorrow and i guarantee it will be people that lack first and second doses i will be treating not people that lack boosters....
