Those with weak or compromised immune systems will now be able to get an additional dose of the COVID-19 vaccine.

The Food and Drug Administration made the announcement late Thursday, stating that those with vulnerable  immune systems due to organ transplants, certain cancers or other disorders can get an extra dose of the Pfizer or Moderna COVID-19 vaccines to better protect themselves.

The announcement comes as the delta variant has increased hospitalizations and deaths due to COVID.

“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, said in a statement.

France, Germany, and Israel, have also made similar recommendations.

High risk individuals who want to get the third shot must wait at least 28 days after getting their second shot to do so.

The FDA has not mentioned anything about those who received the Johnson & Johnson single-dose vaccine.

The recommendation for an additional dose of the vaccine is only directed towards those who are considered high risk.
