FDA Expands COVID-19 Booster Eligibility to Millions More Americans

Strategic Insights -

The Food and Drug Administration has authorized an additional dose of the Pfizer or Moderna vaccine for Americans 50 and older, as well as certain younger people with severely weakened immune systems. This decision expands the eligibility for a booster shot to millions more Americans, especially those with chronic illnesses such as heart disease or diabetes. The Centers for Disease Control and Prevention has recommended the extra shot as an option but advises against a rush. This move comes as COVID-19 cases have dropped to low levels in the US, but health officials are cautiously monitoring the emergence of newer virus mutants.

Key Takeaways:

  • The FDA has authorized a fourth dose of the Pfizer or Moderna vaccine for Americans 50 and older, as well as certain younger people with severely weakened immune systems.
  • The decision expands the eligibility for a booster shot to millions more Americans, especially those with chronic illnesses such as heart disease or diabetes.
  • The Centers for Disease Control and Prevention has recommended the extra shot as an option but advises against a rush.
  • Dr. Rochelle Walensky, CDC's director, emphasizes that the most vulnerable groups, such as older Americans and those with chronic illnesses, should consider another shot.
  • Only about half of Americans eligible for a third shot have gotten one, and the government urges them to get up to date.
  • Two shots plus a booster still offer strong protection against severe illness and death, even during the winter surge of the super-contagious omicron variant.
  • Pfizer had asked the FDA to clear a fourth shot for people 65 and older, while Moderna requested another dose for all adults.
  • The FDA's vaccine chief, Dr. Peter Marks, said regulators set the age at 50 because that's when chronic conditions that increase the risks from COVID-19 become more common.
  • Tuesday's decision allows those with severely weak immune systems to get a sixth dose, as the FDA had allowed a fourth dose only for the immune-compromised as young as 12.
  • Protection against milder infections naturally wanes over time, but the immune system builds multiple layers of defense, and the type that prevents severe illness and death is holding up.

Statistics:

  • Around half of Americans eligible for a third shot have gotten one.
  • Two doses were nearly 80% effective against needing a ventilator or death during the US omicron wave.
  • A booster pushed that protection to 94% effectiveness during the same period.
  • Vaccine effectiveness was lowest (74%) in immune-compromised people, the vast majority of whom hadn't gotten a third dose.
  • Israel reported a reduction of 92 deaths among more than 328,000 people who received the extra shot, compared to 232 deaths among 234,000 who skipped the fourth dose.
