China News Service, Beijing, December 9th (Wei Xianghui) Recently, there have been rumors on the Internet that being infected with the new crown virus is equivalent to getting a vaccine once, and some people even said "good morning, good morning".

  So, is this statement valid?

  Li Tong, chief physician of the Department of Infectious Diseases of Beijing Youan Hospital and medical expert of Xiaotangshan Fangcang Hospital, once told Chinanews.com that

although after being infected with the new coronavirus, immunity against the strain will be obtained within a certain period of time, it does not mean that there is no will re-infect.

  Li Tong once introduced that it is true that some infectious diseases can be easily caught once, such as measles, rubella, mumps, hepatitis A, etc.

The reason is related to the characteristics of these pathogenic microorganisms. After infection, the body will use the previously formed immune mechanism to protect itself.

  However, the new coronavirus is another kind, and one infection does not guarantee lifelong immunity.

It is said that there is also influenza with similar characteristics. Due to the large number of virus types and rapid mutation, it is easy to escape from the human immune mechanism.

This is why the flu vaccine should be vaccinated every year, because the probability of repeated infection is high.

  Li Tong once reminded in particular that for the same new coronavirus, different strains have different abilities to cause multiple infections.

Omicron was more likely to cause reinfection than Delta and previous variants.

In addition, repeated infection still has a certain risk of severe disease, which will be transmitted to high-risk groups such as the elderly at home and people with underlying diseases.

  "Try to let yourself and the people around you get infected later and less." Li Tong once said that even if you have been infected, you still need to take good protection, and it is necessary to get vaccinated after infection.
