PFIZER, BIONTECH TO SEEK AUTHORIZATION FOR COVID-19 BOOSTER SHOT AS DELTA VARIANT SPREADS


10/07/2021




Aslıhan DOĞRU -TDO- Pfizer announced that it wants approval for the 3rd dose vaccine in the United States (U.S.) because the BioNTech vaccine developed against Covid-19 will be effective and increase immunity in the last 12 months against different new variants of coronavirus (Covid-19) that have been effective recently.

Most of the new cases in the United States are Delta variants, officials say.

Experts are investigating whether a third dose of the vaccine is necessary to increase body resistance and provide a strengthening effect due to antibodies that decrease over time.
