Doctors disapproved the need for revaccination against COVID-19, and too frequent administration of drug repeated doses can cause myocarditis and Guillain-Barré syndrome.
An international group of scientists that includes WHO staff authored the article with the recommendations.
In their opinion, the existing vaccines are quite effective, and there is no urgent need for mass revaccination now.
In addition, as the healthcare professionals noted, too early or frequent administration of repeated doses of the drugs can cause myocarditis and Guillain-Barré syndrome.
This refers to, according to their data, both mRNA vaccines (Pfizer/Biontech and Moderna) and drugs based on adenovirus, including the Russian Sputnik V.
The article stresses that the benefits of primary vaccination against COVID-19 far outweigh the risks of contracting coronavirus.
It is noted that before recommending the booster doses of the vaccines, specialists will need to conduct appropriate research.
