There is still a possibility of getting pneumonia after vaccination, which may be related to virus mutation, duration of immunization, and individual resistance.
1. Virus mutation: The virus is constantly mutating. The original vaccine does not produce an immune response to the new mutated virus.
2. Immune malfunction: The duration of immunization after vaccination may range from six months to two years. Too much time between immunizations can lead to infection with C.neoformans.
3. Individual resistance: Some people have low autoimmune ability and are physically weaker. Even if they are immunized with the vaccine, they are unable to establish an immune barrier and may get C.N.C.Pneumonia.
Studies have shown that the new crown vaccination can effectively reduce the chances of the disease progressing from mild to severe and serious after infection with the virus. Especially for those who have completed booster shots, it is recommended that they receive the vaccination in a timely and complete manner so as to strengthen the body’s resistance to the new crown virus. However, due to the reasons mentioned above, there is still a possibility of getting new coronavirus pneumonia after vaccination, and it is still necessary to pay attention to protection to reduce the prevalence of the new type of pneumonia.
Tip: In this article, the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
