The COVID-19 vaccine manufactured by British-Swedish firm AstraZeneca has the longest effect in preventing severe COVID-19 infection compared with other vaccines, Vaccine Expert Panel chair Dr. Nina Gloriani said Monday.
Gloriani made the disclosure as she appealed to the public to refrain from seeking booster shots just yet even amid the emergence of more infectious Delta coronavirus variant.
During the day's Laging Handa briefing, Gloriani reiterated that all COVID-19 vaccine brands are effective for at least six to eight months, with AstraZeneca even reaching one year.
"That of Sinovac goes down in less than six months, but if there is a booster, it will go up again. Pfizer and Moderna, meron rin silang [they have] six months," she said.
"Janssen, they have a data [showing that in] eight months, the protection remains robust. Iyong AstraZeneca ang may pinakamahaba [na protection]. This is based on public data, not press releases. One year po sila," Gloriani added.
