Food and Medication Quality Department under the Ministry of Health and Social Services of the United States expressed uncertainty in the need to revaccinate from COVID-19 in the country. This is reported by TASS with reference to the report.
The report says that there are evidence that protection after vaccination from coronavirus weakens over time. There are studies that do not confirm this.
Also in the report presents the opinion on publications, which refers to research, which indicate the benefits of the use of third (booster) doses of the vaccine from COVID-19. The management stated that there were factors that could “affect their reliability.” Experts noted that it is likely that the most accurate studies that refer to the effectiveness of vaccines for the US population are those that are held in the country.
Earlier it was reported that the White House made mandatory booster doses for all grafted citizens. The third vaccination must be made eight months after the second dose.
Earlier it was reported that The Lancet Medical Journal published an article on the uselessness of mass revaccination, which states that there is no need for re-vaccination yet, since the existing vaccines are sufficiently effective. It is noted that too frequent or premature administration of repeated doses can lead to myocarditis and hyena-barre syndrome. At the same time, for people with a weak immune system, revaccination can be useful.
