Currently, COVID-19 vaccination is still the most effective protection measure for individuals. Experts said that according to the research results at home and abroad, the completion of the basic immunization of COVID-19 vaccine has played a great role in preventing infection and reducing the severity of illness. However, over time, most people’s immunity is decreasing, and the protective effect of vaccines is also weakened. Therefore, timely enhancement of immunity is very necessary. On the one hand, the antibody produced by strengthening immunity has stronger persistence. Half a year after strengthening immunization, although the antibody also decreased, it was still higher than the peak after two or one dose of vaccination. On the other hand, strengthening immunization can better deal with the mutant strain. Relevant studies on strengthening immunization with inactivated vaccine show that after vaccination, the antibody increases, which will have a better protective effect on the mutant strain. It is suggested that the citizens who meet the inoculation conditions (including 3-11 year old children without vaccination and over 60 years old) should take the initiative to complete the whole vaccination of COVID-19 vaccine and build an immunization barrier as soon as possible. People who have completed vaccination for more than 6 months should be vaccinated with NCV booster injection as soon as possible.
