The data show that one dose may significantly reduce the risk of transmitting the virus. • In addition, an Israeli study conducted among asymptomatic patients states that the risk of infection decreases 5 to 10 times starting a week after the second dose.

One dose of the coronary vaccine from the American pharmaceutical company Pfizer may significantly reduce the risk of transmitting the virus to others, according to a British study published today (Friday).
The researchers analyzed the results of thousands of corona tests among medical teams in Cambridge.
"Our findings show a dramatic decline in the rate of positive screening tests among asymptomatic health teams, following a single dose of Pfizer's vaccine," said Nick Jones, an infectious disease specialist who led the study.
After separating the test results into vaccinated and unvaccinated, it was found that 0.8% of the unvaccinated tests were positive for the virus.
This is compared to 0.37% of staff tests less than 12 days after vaccination and 0.2% of tests 12 days or more after vaccination.
It should be noted that the study has not yet undergone peer review.

In fact, there has been a fourfold decrease in the risk of infection among health care workers 12 days or more after the first vaccination, and their protection stands at 75% - according to Mike Wakes, an infectious disease specialist.
According to him, the infection rate decreased even less than 12 days after the vaccination.
"This is great news - Pfizer's vaccine for corona not only provides protection against coronary heart disease, but also reduces the potential for virus transmission to others," Weeks said.
However, "keep in mind that the vaccine does not provide complete protection for everyone."
Alongside all this, the AMN Information and Knowledge Center report published today stated that "it has not yet been determined whether a vaccinated person infected with the virus transmits it to others who have not yet been vaccinated or are unable to be vaccinated, and further research is needed. It is not hermetic and careless handling can cause infection even among some of the vaccinated, therefore, care must be taken to wear masks and physical distance. "

"In order to assess the protection afforded by the vaccine against infection, the data from the initiated tests performed as part of a protective program for fathers and mothers were analyzed, in which staff teams are routinely examined regardless of the onset of disease symptoms," it said.
"An analysis comparing the vaccinated and non-vaccinated groups shows that the vaccine reduces the risk of contracting the virus 5 to 10 times in the population up to the age of 65. This is a significant figure, which we believe will be reduced in the prevalence of the disease among the vaccinated population. ".
Meanwhile, Prof. Hezi Levy, Director General of the Ministry of Health, spoke today with the directors of the HMOs. He updated that an agreement has been signed with Pfizer for additional doses for another four weeks, which allows vaccination for all 16-year-olds in Israel, including recovering patients. Final on the subject of recovery vaccines in one dose.
