The largest realistic study ... the "Pfizer" vaccine "protects by 95%"

The largest study on the ground to date on the Pfizer / Biontech vaccine confirmed that the vaccine provided more than 95% protection against Covid-19, but found that its level decreased dramatically when people received only one dose of the two recommended doses.

The study authors said, based on the national vaccination campaign in Israel, that there is realistic evidence that the epidemic can be eliminated through rapid global vaccination programs.

An analysis of health data from Israel, one of the countries with the highest percentage of fully vaccinated adults, showed that the vaccine was very effective in protecting the elderly, while the British version of the epidemic was the most dominant infection, according to the results published in the medical journal "The Lancet".

The study found that two doses provided 95.3% protection from infection and 96.7% protection from death, seven days after the second dose.

After 14 days, this protection increased to 96.5% and 98%, respectively.

However, protection was much lower in people who received only one dose of the vaccine.

After the first dose, between seven and 14 days, the infection protection rate was 57.7% and the death protection rate was 77%.

The study authors said that a single dose may provide a shorter window of protection, especially in an environment where new variants of the virus appear.

Jonathan Ball, professor of molecular virology at the University of Nottingham, who was not involved in the research, noted that "the most important thing is that the study shows that two doses of the vaccine significantly increase immunity and protection."

"That is why it is important for people to get the two doses," he added.
