U.S. health officials recommending all Americans get COVID-19 booster shots
U.S. health officials Wednesday announced plans to dispense COVID-19 booster shots to all Americans to shore up their protection amid the surging delta variant and signs that the vaccines' effectiveness is slipping.
The plan, as outlined by the director of the U.S. Centers for Disease Control and Prevention (CDC) and other top authorities, calls for an extra dose eight months after people get their second shot of the Pfizer-BioNTech or Moderna vaccines.
The doses could begin the week of Sept. 20.
"Our plan is to protect the American people, to stay ahead of this virus," CDC director Dr. Rochelle Walensky said as the agency cited a raft of studies suggesting that the vaccines are losing ground while the highly contagious variant spreads.
People who received the single-dose Johnson & Johnson vaccine will also probably need extra shots, health officials said. But they said they are waiting for more data.
Officials said that before any booster program starts up, the U.S. Food and Drug Administration and a CDC advisory panel would need to evaluate the safety and effectiveness of an extra dose.
'A responsibility' to give maximal protection
"We have a responsibility to give the maximum amount of protection," U.S. President Joe Biden said at the White House. He added that extra doses are also "the best way to protect ourselves from new variants that could arise."
The announcement came the same day the Biden administration said it would require nursing homes to mandate vaccinations for staffers in order to continue receiving federal funds. Hundreds of thousands of nursing home workers remain unvaccinated, despite the heightened risk of fatal infections among elderly residents.
U.S. officials said it is "very clear" that the vaccines' protection against infection wanes over time, and they noted the worsening picture in Israel, which has seen a rise in severe cases, many of them in people already inoculated.
They said the U.S. needs to get out ahead of the problem before it takes a more lethal turn here and starts leading to increasing hospitalizations and deaths among the vaccinated.
