The U.S. Centers for Disease Control and Prevention this week released data showing that effectiveness of the COVID-19 vaccine booster wanes markedly in the months following that shot, though the agency still said uptake of the booster is important for fighting against the virus.
The agency said in a press release that studies showed effectiveness against COVID-19 emergency department and urgent care incidents “was 87% and 91%, respectively, during the 2 months after a third dose [of the booster],” but that it “decreased to 66% and 78% by the fourth month after a third dose.”
The CDC said that “protection against hospitalizations exceeded that against ED/UC visits” with the shot.
Facebook parent company Meta will require its in-person workers to receive a booster shot in addition to a COVID-19 vaccine, the company announced Monday.
By March 28, Meta employees must have received the booster to use the in-person offices of Facebook, WhatsApp and Instagram, The Wall Street Journal reported. Meta is reportedly delaying the reopening of its offices until late March due to the requirement.
“We’re focused on making sure our employees continue to have choices about where they work given the current COVID-19 landscape,” Janelle Gale, Meta’s vice president of human resources, said in a statement, CNBC reported. “We understand that the continued uncertainty makes this a difficult time to make decisions about where to work, so we’re giving more time to choose what works best for them.”
