The US Centers for Disease Control and Prevention (CDC) on Monday issued a new guidance recommending booster shots for all vaccinated people 18 and older, Bloomberg News reported.
The guidance, which previously said adults “may” get boosters, now says they “should” get a third dose of the Moderna or Pfizer shot six months after their second dose. The same recommendation applies to those who received the single-shot Johnson & Johnson vaccine but after only two months.
