In the new wave of epidemics, many people may think that they do not need to be vaccinated after being infected. This is an incorrect view. In the three years since the COVID-19 epidemic, there have been enough data to prove that vaccination with effective vaccines can bring greater benefits. First of all, vaccines are safer. Infection is usually accompanied by severe symptoms, and the effectiveness of bivalent booster injections against infection can reach more than 50%. Researchers have found that there are huge differences in antibody levels in recovered patients after infection. Thousands of times, higher antibody levels mean lower risk of infection; in natural infection, the new coronavirus infects cells in the respiratory tract, and the immune system responds to a large number of viruses, so a relatively large diversity of antibodies is produced, compared to The underlying vaccine targets the spike protein that is crucial to the virus. Its antibody diversity is not as good as that of naturally infected people, but it produces a high level of highly targeted antibodies. The two can be compared to the difference between a shotgun and a sniper rifle. last year’s study found that the level of neutralizing antibodies in the recovered patients increased by a thousand times after vaccination; It is believed that the vaccine is not very effective, but this slight injury is based on the widespread vaccination of effective vaccines.
