According to the "New York Times" reported on the 19th, a recent study in the United States showed that compared with infected people who have not been vaccinated against the new crown, the infected people who have been vaccinated have stronger resistance. Vaccinators get a natural boost to their immune system, at least in the short term, which scientists call "mixed" immunity, which is the result of a combination of pre-existing vaccine antibodies and natural antibodies to protect the body from infection.
Humpit, an infectious disease expert at the University of California, San Francisco, said the boost in immunity from natural infections could be similar to a fourth dose of the vaccine. However, if people are infected before they are vaccinated or boosted, there is also a possibility of "mixed" immunization.
It has been reported that while some doctors and immunologists in the United States agree that "mixed" immunity can provide additional protection, they also point out that the intensity of this protection may vary from person to person and weaken over time. People who are immunocompromised, older, or at higher risk of serious disease may produce fewer antibodies and their antibody levels may decline more rapidly than younger, healthy people.
