As of now, there have been secondary infections of new coronavirus pneumonia in many parts of the world.
A case study article published in October by the authoritative medical journal The Lancet, which has many confirmed cases of secondary infections that are more serious than when they were first infected.
article stated that the situation of secondary infection should be paid attention to in the development and application of vaccines.
Compared with natural coronavirus infection, a professor of immunology at Yale University once pointed out that the new coronavirus vaccine currently being developed has more advantages in stimulating the human immune response. Therefore, repeated infections do not mean that the immune protection capacity brought by the new crown vaccine will be equally short-lived. How long can the new crown vaccine provide for protection will take time and large-scale clinical trials to verify.
