FDA is now reviewing the applications to authorize the use of third or booster vaccine shots of some COVID-19 vaccine brands.
In a taped address broadcasted on Wednesday, November 3, Food and Drug Administration (FDA) Director General Eric Domingo said that regulatory experts are currently reviewing requests for authorization sent by Pfizer, AstraZeneca, Sinovac, and Sputnik V.
According to Domingo, the companies requested to include the use of a third dose or booster dose in the emergency use authorization. He added that experts are now studying the scientific data they sent.
Moreover, the FDA Director General said the FDA is studying the mixing and matching particular COVID-19 vaccine brands for booster jabs, as per the Department of Health’s request.
The official mentioned they are examining the efficacy and safety of mixing the complete dose of AstraZeneca with Pfizer for the third dose, Sinovac then AstraZeneca or Pfizer, and Moderna with Pfizer as the booster jab.
National vaccine czar Carlito Galvez Jr. provided the projected timeline for the administration of booster jabs for healthcare workers, and third dose for senior citizens and immunocompromised individuals, or those with impaired immunity due to existing illness.
He said they are looking into releasing the final guidelines for booster and third jabs by November and implementing them by November 15.
However, the authority added the national government will only give the shots after acquiring an amended emergency use authorization (EUA) from FDA, and once the World Health Organization’s Strategic Advisory Group of Experts (SAGE) on Immunization releases its recommendation.
Booster shots are given to individuals whose immunity decreases over time after completing their jabs. Meanwhile, an additional dose is given to individuals who didn’t reach the ideal immune response level. Additional doses are usually given to the elderly or those who are immunocompromised.
