COVID-19 Vaccine Study: The researchers found that over the study period, effectiveness of the vaccine against allS-COV-2 infections declined, falling from 88 per cent within one month after receiving two vaccine doses to 47 per cent after six months.
Two doses of the Pfizer COVID-19 vaccine are 90 per cent effective against hospitalisation from the disease for all variants, including Delta, for at least six months, according to a study published in The Lancet journal on Tuesday.
The researchers found that over the study period, effectiveness of the vaccine against allS-COV-2 infections declined, falling from 88 per cent within one month after receiving two vaccine doses to 47 per cent after six months.
However, the effectiveness of Pfizer (BNT162b2) vaccine against hospitalisations remained at 90 per cent overall for all variants, they said.
The study underscores the importance of improving COVID-19 vaccination rates worldwide and monitoring vaccine effectiveness to determine which populations should be prioritised to receive booster shots, the researchers said.
