According to a recent study, a booster dose of Pfizer's COVID-19 vaccination can protect individuals over 60 from infections and severe sickness immediately after injection. This new research was carried out in Israel.
During the current spike in the nation owing to the Delta variant, israel gave the third dose of Pfizer's mRNA Covid vaccine. It was initially authorised for those aged 60 and up who had taken a second dose of the vaccine at least five months before. Those who got a booster (third dose of the BNT162b2 vaccination) had significantly reduced the incidence of confirmed COVID-19 and severe illness as per the reading printed in the New england Journal of Medicine.
They looked at data from 1,137,804 people aged 60 and up who had been completely vaccinated (two doses of BNT162b2) at least 5 months before the research. The study found that individuals who received a booster dose had an eleven-fold reduced incidence of infection and a nearly twenty-fold lower rate of serious illness than those who had just two doses at least 12 days later.
The US Food and Drug Administration (FDA) has concluded that booster doses of the Covid-Delta flu vaccination are not required for the general public. Booster doses are not necessary at this time in the pandemic, according to a review by international specialists. Efficacy against severe Covid is so great, even for the Delta version, that booster doses are not necessary. The FDA's view on booster injections comes as the Biden administration debates whether or not third doses against Covid are necessary.
