After two shots of COVID-19 vaccine, COVID-19 was infected. Experts said there might be "breakthrough infection"

In this round of the Nanjing Lukou Airport epidemic, most of the confirmed positive patients were airport cleaning workers. Due to the large flow of personnel, it has affected multiple provinces and cities. However, it is inconceivable that many confirmed cases have received two shots of vaccine. Why did they get COVID-19 after two shots of vaccine? Let's go take a look together. During the vaccination

epidemic, vaccination with COVID-19 vaccine is indeed one of the most effective ways to curb the spread of the virus, but it will not provide 100% protection. As for COVID-19 after two shots of vaccine, experts said that it was still diagnosed after vaccination, which may be a "breakthrough infection".

In this case, "breakthrough infection" is possible even if the COVID-19 vaccine is very effective. Therefore, we must not think that vaccination will not infect COVID-19, which is obviously wrong. At the same time, it is recommended that everyone take protective measures when going out, such as wearing masks and disinfecting frequently.
