The US Food and Drug Administration has given the go-ahead for Americans with weak immune systems to get an extra dose of COVID-19 vaccines, Bloomberg reported.

  • The third shot is allowed to be given at least 28 days after the second dose and will only be given for those with weakened immune systems. Data is being collected for other vaccinated groups.
  • Among those eligible for a third dose are recipients of organ transplants and individuals with immune compromising conditions such as cancer, HIV, and multiple sclerosis, among others.
  • The approval covers vaccines made by Moderna Inc. and those by the partnership of Pfizer Inc. and BioNTech SE in efforts to increase protection for the more vulnerable population.

The US joins other countries such as Israel, Germany, and France, which already offer boosters to vulnerable groups, possibly worsening vaccine inequality. MRNA is up 3.56%, PFE up 0.29%, and BNTX up 3.89% premarket.
