Novel coronaviruses may also mutate. New coronavirus pneumonia comes from coronavirus, there are more than 50 kinds of coronavirus, can infect humans plus the new coronavirus infection a total of 7 kinds, the previous 6 kinds include the 2003 SARS and the emergence of the Middle East in 2012 MERS, that is, the Middle East respiratory syndrome, so coronavirus belongs to the easily mutated virus, once the coronavirus continues to mutate, had suffered from coronavirus pneumonia patients may not resistance. It is similar to influenza, which may have different strains of influenza each year, and after having been infected with influenza, you may still have influenza the following year. Novel coronavirus pneumonia may also continue to mutate, rendering antibodies that have been produced ineffective, but the probability of a major mutation is low. Therefore, vaccine development needs to take into account the probability of virus mutation and develop a vaccine that can ensure that the virus remains effective after minor mutations. According to current studies on novel coronavirus pneumonia, no significant mutations have been found. Content source: Dr. You Lai
