When can COVID-19 booster injection be administered? How often is the interval between the third dose of COVID-19 vaccine

The effectiveness of the vaccine is not permanent. The longer the time goes by, the lower the effectiveness of the vaccine will be. So many people plan to vaccinate with enhanced COVID-19 vaccine, which can effectively improve the protection rate. When can the booster COVID-19 vaccine be administered? How long is the interval between the second injection? Let's take a look below. Enhanced vaccination

At present, it is not necessary for the general population to vaccinate with enhanced COVID-19 vaccine. Some key populations and high-risk industries, such as customs, border inspection, aviation, quarantine points, designated medical institutions, etc., who need to go to high-risk areas for overseas epidemics, as well as people over 60 years old, can receive enhanced immunization. Experts point out that the interval between the second and third doses is about 6 months, as the vaccine protection rate will continue to decline after 6 months. Vaccination with booster shots can improve the protection rate. Among all vaccinated individuals, there were no serious adverse events, and the immunogenicity results are currently being monitored.
