Israeli study: How effective is the Pfizer / BioNTech vaccine in adolescents

The Pfizer / BioNTech vaccine against coronavirus is also very effective in adolescents, according to a new Israeli-American study, the largest ever in the world based on real data. This is the most comprehensive evaluation of the effectiveness of a Covid-19 vaccine in an entire country and the first to address the recent period in which the Delta variant is predominant.

Researchers from the Clalit Research Institute and Harvard University, who published the study in the New England Journal of Medicine, analyzed data on 94,354 vaccinated adolescents aged 12 to 18 years between June and September 2021, a period between June and September 2021. with the fourth wave of infections, when the Delta variant had prevailed in Israel. The researchers compared an equal number of unvaccinated adolescents.

It was found that in fully vaccinated adolescents, seven to 21 days after the second dose, the risk of symptomatic Covid-19 disease was reduced by 93% compared with their unvaccinated peers, while the risk of infection (regardless of symptoms) was reduced by 90%. .

But 14 to 20 days after the first dose, the risk of symptomatic Covid-19 was 57% lower in vaccinated people, while the risk of infection was 59% lower than in unvaccinated adolescents. There were insufficient data to estimate the risk reduction in vaccinated patients with serious illness, hospitalization and death, all of which are rare among adolescents.

“The results of the study show convincingly that one week after the second dose, this vaccine is highly effective in adolescents against symptomatic Covid-19 and against any infection,” said Professor Ran Balitzer, director of the Clalit Institute. “They are a strong argument in favor of the choice of vaccinating adolescents, especially in countries where the virus is now widespread.”
