Zhang Wenhong, director of the National Center for Infectious Diseases Medicine, talks about the fourth vaccination. Do people in China need a fourth dose of vaccine?
First of all, people are more susceptible to COVID-19 virus because of fatigue of the immune system.
The human immune system has a certain ability of self-repair, and if vaccination continues, immune failure may occur. Is this what people often say? Extremes must be reversed? Too many times of vaccination with COVID-19 vaccine not only can't achieve good immune effect, but also may lead people into immune fatigue crisis. It is too early to say that the fourth dose of vaccine will be popularized in China unless hospital research is needed to think that the fourth dose of vaccine is of great benefit to group immunity.
Second, the domestic three needles have reached a good antibody concentration, so there is no need to waste too many medical resources.
China has a large population, and most people have received three doses of COVID-19 vaccine. Judging from the immune effect on the epidemic situation, the probability of serious infection is relatively low, and people are farther away from the collective immune barrier. The fourth dose of vaccination can be applied in high-risk emergency areas, and the general population does not need the fourth dose of vaccination.
So, which countries do you think are likely to take the lead in the fourth vaccination in the world?
