The head of the Federal Centers for the Control and Prevention of Diseases (CKPZ) of the United States Rochelle Valenski said that scientists received new data proving that vaccinated people could be carriers of the coronavirus delta version. A large amount of virus may be present in the nasopherler of people, which indicates the need to continue to wear masks. However, the study itself will be published later. It is reported by the New York Times.
Anxious discovery contradicts the fact that scientists have previously observed in vaccinated people infected with previous versions of the virus that have not been able to infect other people. This may mean that even completely vaccinated represent the same danger to others, as well as non-unqualified people.
As of July 29, in the United States, 67 thousand new cases of coronavirus infection per day are registered on average. If vaccinated people really transmit delta-option, they can contribute to incidence growth, although it is likely to a lesser extent than non-unqualified. Those scientists who have already familiarized themselves with the results of a new study, they say that it convincingly proves the need to carry masks in the premises even those who have already received two doses of the vaccine.
Earlier, Rochelle Valenski has already declared a decrease in the effectiveness of vaccines against the Indian strain of coronavirus and the possibility of its spread by grafted people. She called on vaccinated and disregard the rules of individual protection. “Vaccination continues to prevent the difficult course of the disease, hospitalization and death, even in the case of the Delta strain,” the specialist reminded.
