Recently, there have been some discussions on the Intern.

Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Preventi.

Wang Huaqing said that in terms of process, after vaccination, when symptoms and related diseases are suspected to be related to the vaccine, the first thing to report is to report to the inoculation un.

How to determine whether the disease after vaccination is related to the vaccine?

Wang Huaqing said that this is an expert diagnosis team composed of multidisciplinary experts to make analysis and judgments based on the survey results and survey conte.

"The general public is more concerned about the relationship in time, that is, the vaccine is given first, and symptoms or diseases appear lat.

In addition to temporal associations, the second factor to consider is biological plausibili.

For example, "Why do we not in principle vaccinate people with immunocompromised live attenuated vaccines now, because live attenuated vaccines could theoretically and biologically cause abnormal reactions in these immunocompromised people?" The risk increases, which is biologically reasonab.

The third is the strength of the associati.

Fourth, "the occurrence of abnormal reactions also has its regulari.

Another factor to consider is the consistency of the association, that is, whether these people who have been vaccinated have similar symptoms or diseases, and the incidence of these similar symptoms and diseases is higher than its baseline level, that is It is said that whether this occurs in both vaccinated and unvaccinated people, but whether there is a higher incidence among vaccinated people, this is the consistency of the associati.

As a final point, consider the specificity of the associati.
