There is no reason why leukemia should occur after receiving the new CAPV vaccine, since it does not cause leukemia. The rumor on the Internet that leukemia was induced after receiving the new type of CRP vaccine is related to a “coincidental reaction”. A “coincidental reaction” means that the vaccinated person was in the incubation period or the pre-morbid stage of a certain disease at the time of vaccination. In the case of leukemia, for example, the patient was already in the pre-morbid stage of the disease before receiving the new coronary pneumonia vaccine, and it so happened that after receiving the vaccine, the leukemia began to show the relevant clinical symptoms. The “coincidental reaction” leads to the false impression that there is a correlation between the two. Therefore, there is no absolute causal link between the development of leukemia and whether or not the vaccine is administered, so it is not scientific to say that leukemia is induced by the vaccination with the new CRP vaccine.
