New data from the Israeli Ministry of Health suggests that the Pfizer / BioNTech and Moderna Covid-19 vaccines may be even more effective than previously thought.

The data, which examined more than 700,000 fully vaccinated people in Israel, found that, according to Israeli Ministry of Health Director Dr. Sharon Alroy Preis, at a press conference on Thursday, only 0.04 percent of people got Covid-19.

The type of vaccine that Israel has used the most is the Pfizer / BioNTech small number of doses vaccine from Moderna. The two vaccines use the same technology and have been shown to be 95% effective in clinical studies.

Some background information:

Israel began its vaccination campaign on December 20th. The data released Thursday included 715,425 vaccinated people who were at least a week after their second dose, giving vaccines time to turn on and maintain immunity. Of these people, only 317 contracted Covid-19 and 16 were hospitalized.

Far more people were interviewed in the data than in the Pfizer and Moderna Phase 3 clinical trials. About 75,000 people took part in these studies, with half receiving the vaccine and the other half receiving a placebo.

The two vaccines were launched in several countries, including the US, Canada, and some European countries. The UK became the first country in the world to vaccinate patients with the Pfizer / BioNTech vaccine last December.
