Data from Israel — which has been vaccinating its elderly population in recent weeks — suggests that mass vaccination can stop the spread of severe COVID-19 symptoms, CNBC reports.

The study — published by the Centers for Disease Control and Prevention — is one of the first real-world data sets of how the vaccine is impacting the world. All of the vaccines were previously reviewed in clinical trials.

  • This is real-world data, showing how the vaccine is actually playing out in the world, according to The Los Angeles Times.

According to the research, the percentage of patients who needed ventilation for severe COVID-19 dropped significantly after vaccinations in the country.

  • “Taken together, these results suggest reduced rates of severe COVID-19 following vaccination,” wrote the researchers, who work at Ben Gurion University of the Negev, Tel-Aviv University and Maccabi Healthcare Services, according to CNBC.
  • “What we see here are early and very encouraging signs that the vaccine is working in the population,” said Florian Krammer, a virologist at Icahn School of Medicine at Mount Sinai in New York City, according to Nature.com.

A look at the numbers

Israel has been one of the leading countries for vaccinations, according to The New York Times. So far, about 84% of the country’s 70 and older population has been fully vaccinated through the Pfizer-BioNTech vaccine, according to CNBC.
