Bivalent Covid Booster Update

The CDC Vaccine Advisory Panel, made up of 14 national experts in infectious disease and vaccine technology, met to review the scientific evidence behind the newly formulated bivalent covid vaccines. The committee strongly recommended that all Americans 12 and older receive inoculation with the updated boosters if their last dose was more than 2 months ago. Those who have had a covid infection during the last 3 months should talk to their healthcare provider to decide on optimal timing for their booster. The CDC also reaffirmed that 2 years of careful vaccine monitoring have shown no harm to fertility or pregnancy.

As was noted on an earlier web post, 99% of all covid infections since late spring have been the result of BA.4 and BA.5 variants. The new bivalent vaccines from Moderna and Pfizer directly protect against these strains. > Read More
