Senior citizens who took a second booster dose of the Pfizer–BioNTech COVID-19 vaccination experienced a 78 percent lower mortality risk than those who only took one booster dose, according to a study from Israel.

The 40-day study, which is yet to be peer-reviewed, was conducted by Israel's largest healthcare provider.

The study took samples from over 5,00,000 people in the 60 to 100 age bracket.

Just under 60 percent of participants had taken a second booster shot of the vaccine, i.e., two additional doses after the first two basic doses.

Others only took one booster shot after the basic two-dose vaccination.

A total of 92 deaths were recorded in group 1 as opposed to 232 deaths in group 2.

"The main conclusion is that the second booster is lifesaving."

However, the report did not take into account individuals who had taken Moderna's vaccine or oral anti-COVID medication.

Meanwhile, just in January 2022, The European Medicines Agency (EMA) had warned that frequent booster shots could have the opposite effect make the immune system weaker.
