Tips for the holiday season.
#covid19vaccine note: Vaccine effectiveness of 50-60% vs symptomatic disease for the new bivalent vaccine is tremendous. Itโs not a base hit, itโs a home run.
Why? The comparison group was already vaccinated x2, x3, x4 and many were previously infected. Thus, this additional protection is amazing because even with all the background immunity, the bivalent cuts your risk in half!
