A US study has found that people who are fully vaccinated against Covid 19 do not need to wear a mask. A comprehensive study of health workers across the United States by the US Centers for Disease Control and Prevention (CDC), the US Centers for Disease Control and Prevention, found that fully vaccinated people could normally walk without masks.

Frontline workers, including health workers, were vaccinated in the United States at the beginning of the vaccination campaign against Corona. The study showed that people who received the full dose of Moderna and Pfizer vaccines administered during that time were 94 percent safe from covid infection. Even a single dose can provide 84 percent protection to people, according to the CDC's weekly report.

According to Dr. Rachel Walenski, director of the CDC, this latest study has helped to loosen previous suggestions on who should wear masks and when. According to him, the information obtained from this study is still strong evidence that the vaccine against Covid 19 is working really well.

According to the CDC, the Covid 19 vaccine has been shown to be effective in preventing coronavirus infections, serious illness and even death. The study also found that vaccines reduce the risk of people spreading the virus.

According to a study conducted by CDC and in Israel, people who have been vaccinated with only the first dose of the virus have a much lower viral load on their body even if they are infected. That is, the number of viruses in the body of an infected person is 4 times less than in those who have not been vaccinated. It also lowers the risk of transmitting the virus from one person to another.
