Since the beginning of the coronavirus epidemic, one of the biggest questions that has plagued researchers is: can a person who has acquired immunity continue to infect another asymptomatically? That is, if someone is vaccinated with the vaccine (so they are “artificially” immunized) but still infected, can they transmit the virus to other people? The question is critical because if the answer is yes, then we have a much, much rougher road ahead in the fight against the virus.
Gábor Kemenesi, a virologist at the University of Pécs, provided fantastic news on the subject in his YouTube video on Wednesday.
It was cited in an Israeli study published on the medical portal medrxiv.org (this country has the highest vaccination rate in the world) that analyzed the impact of vaccination on 19-50 people in other groups in society, especially young people. . You can also ask whether people under the age of 19 to 50 are protected from infection by getting vaccinated. The answer seems to be yes!
The study shows that
As vaccination rates among those aged 19 to 50 increased, so did the number of cases among those under 18.
But not just between them. The research was carried out by specialists from January 16 to March 20 and the result shows that with the increase in vaccination rates, the number of new infections fell dramatically at all ages.
Gábor Kemenesi also mentioned another study he had previously published about: people vaccinated with the Pfizer and Moderna vaccines in the US Between December 2020 and March of this year were evaluated by continuous testing in a sample of 2,500-4,000 people . The objective was the same as in Israel: to find out the risk of asymptomatic infection. It was found that 14 days after the first vaccination, 80 percent of those vaccinated were also protected against asymptomatic infection, and after the second dose, 90 percent of them obtained the same protection.
This is cruelly good news, we see the same in Israeli data, and that is why the epidemic is slowing down for them.
– said the researcher, adding that the virus can still remain among us, but in a tenth as before.
