The Lancet magazine published an article criticizing the massive revaccination against coronavirus.
The recommendations were made by an international group of scientists, including the staff of the World Health Organization (WHO).
According to experts, the existing vaccines are quite effective, and there is no urgent need for mass revaccination now.
In addition, as noted by doctors, too early or frequent administration of repeated doses of drugs can lead to myocarditis and Guillain-Barré syndrome.
"While the benefits of primary vaccination with COVID-19 clearly outweigh the risks, they can still arise if booster doses are widely deployed too early or too often," the article says.
This applies, according to scientists, as mRNA vaccines (for example, Pfizer and Moderna), and drugs based on adenovirus - including the Russian "Sputnik V".
The specialists noted that they see no reason to conduct revaccination if the general immunity among the population remains high. According to the researchers, a decrease in antibody levels does not necessarily mean a decrease in the effectiveness of a vaccine over time.
It is noted that experts will need to conduct appropriate research before recommending booster doses of vaccines. Also, doctors insist that the drugs should become available all over the world, since many, according to them, still do not even have access to primary vaccination.
Earlier, WHO called for an extension of the moratorium on booster vaccination against COVID-19 at least until the end of the year, so that at least 40 percent of the population could be vaccinated in each country.
