Around 100 million people have received a Covid-19 vaccine in “real world” settings. There are still many unknowns, and watching the knowledge unfold is fascinating. Luckily, so far, it also looks promising.

There aren’t many places better to seek vaccine-related data in than Israel. A country of fewer than 10 million citizens that already vaccinated more than a third of its population. Israel is way ahead of the curve in vaccine rates. Being a “tech-friendly” nation, it’s also keeping score; a detailed breakdown of all Covid-19 related statistics is constantly updated on the Ministry of Health’s website.

On January 13, I wrote about initial data coming from Israel’s private community health services. Large studies showed promising efficiency among people after the first dose of the Pfizer-BioNTech’s vaccine.

Two and a half weeks later, more than 1.7 million Israelis have already received their second vaccine dose. Initial data has started emerging on the effects of being fully vaccinated — that is, at least a week after receiving the second dose. Here’s some of that data from the Israeli Ministry of Health:

Over 60-year-olds:

Data was collected from 668,100 people who were fully vaccinated.

  • Among them, 473 were diagnosed positive to Covid-19 (0.07%).
  • Among those positive, 38 were hospitalized.
  • 11 were in serious condition.
  • Three were in critical condition.
  • Two died.
