Department of Health Secretary Francisco Duque has warning the public against using different kinds of COVID-19 vaccines.
In a Senate hearing, Duque said the protocol was to give individuals two doses of the coronavirus vaccines of the same brand.
“You wouldn’t want to toy with the idea of giving different vaccines for the simple reason that if an adverse event following immunization does happen, or an adverse event of special interest, we are going to struggle which of these two different vaccines must have caused it,” Duque said.
Senate President Tito Sotto asked the question if a person can use two vaccine brands at the same time.
Philippine Medical Association’s Dr. Lulu Bravo also cautioned about the usage of two different brands.
“This is not recommended, your honor. Interchangeability — that is what we call it — is actually a no-no, because no company will be willing to do a study on that kind of a process. Most of the results that we will get, if these were done, will not really be based on standard procedures. This is not a recommended procedure that you will interchange or use another vaccine after you have used another one before,” she added.
On Thursday, the Food and Drug Administration granted the first Emergency Use Authorization to Pfizer.
FDA Chief Eric Domingo said what used to be a six month process for getting approval, the EUA for Pfizer was shortened to 21 days.
“The FDA is now granting an emergency use authorization to Pfizer-BioNTech vaccine,” Domingo said.
The vaccine showed 95% efficacy in all its trials while 92% on all racial groups.
Domingo said that close surveillance and monitoring are needed for more adverse effects.
Domingo added that vaccinations may be done only by health professionals and they should be ready to manage for any possible adverse reactions.
The vaccine should only be given to individuals 16 years and above.
“It is reasonable to believe that Pfizer and BioNTech vaccine is effective to prevent COVID-19. The known benefits of vaccines outweigh the adverse effects of the vaccine,” Domingo added.
The FDA said that pending AstraZeneca, Russia’s Gamaleya for Sputnik V and China’s Sinovac or Coronavac.
