Bahrain : U.S. regulators say transplant recipients and others with severely weakened immune systems can get an extra dose of the Pfizer or Moderna COVID-19 vaccines to better protect them as the delta variant continues to surge, reports AP.
The late-night announcement Thursday by the Food and Drug Administration applies to several million Americans who are especially vulnerable because of organ transplants, certain cancers or other disorders. Several other countries, including France and Israel, have similar recommendations.
It’s harder for vaccines to rev up an immune system suppressed by certain medications and diseases, so those patients don’t always get the same protection as otherwise healthy people — and small studies suggest for at least some, an extra dose may be the solution.
“Today’s action allows doctors to boost immunity in certain immunocompromised individuals who need extra protection from COVID-19,” Dr. Janet Woodcock, the FDA’s acting commissioner,
The FDA determined that transplant recipients and others with a similar level of compromised immunity can receive a third dose of the vaccines from Pfizer and Moderna at least 28 days after getting their second shot.
The FDA made no mention of immune-compromised patients who received the single-dose Johnson & Johnson vaccine.
The announcement comes as the extra-contagious delta version of the coronavirus surges through much of the country, pushing new cases, hospitalizations and deaths to heights not seen since last winter.
Importantly, the FDA’s decision only applies to this high-risk group, estimated to be no more than 3% of U.S. adults. It’s not an opening for booster doses for the general population.
Instead, health authorities consider the extra dose part of the initial prescription for the immune-compromised. For example, France since April has encouraged that such patients get a third dose four weeks after their regular second shot. Israel and Germany also recently began recommending a third dose of two-dose vaccines.
Separately, U.S. health officials are continuing to closely monitor if and when average people’s immunity wanes enough to require boosters for everyone — but for now, the vaccines continue to offer robust protection for the general population.
The Centers for Disease Control and Prevention is expected to formally recommend the extra shots for certain immune-compromised groups after a meeting Friday of its outside advisers.
