CDC Endorses “Mix and Match” Approach to Boosters

The CDC has endorsed a third COVID-19 booster shot for Moderna and Johnson & Johnson vaccines, following FDA authorization. They also support a mix and match approach, allowing booster shots to differ from initial vaccinations. This marks a significant step in expanding the Biden administration's booster campaign, which began with Pfizer. Recommendations include a booster six months after the second dose for those 65 and older, and adults 18+ in high-risk settings. Johnson & Johnson recipients can get any booster two months after their initial dose.
