As long as the third booster injection of COVID-19 vaccine is inoculated, the gold code of health code will be upgraded to diamond code. Up to now, according to incomplete statistics, Anhui, Fujian, Henan, Heilongjiang, Hubei and other provinces have definitely started to strengthen vaccination.
10- 10, Harbin city, Heilongjiang province carried out intensive immunization for people over 8 years old who had completed two doses of inactivated vaccine or one dose of adenovirus vector vaccine for 6 months, and further established a solid immune barrier. After the vaccination began, Harbin citizens went to the inoculation point in their community to queue up for vaccination.
It is reported that this vaccination will give priority to strengthening the immunization of people at high risk of infection, including ports, isolated places, key personnel to ensure the basic operation of society, and some key people over 60 years old.
Why should we strengthen immunization?
According to the existing observation and research data, COVID-19 has made remarkable achievements in preventing severe illness and death after full vaccination. However, after inoculation for a period of time, some people's immunity decreased and their protective effect weakened. After strengthening immunity, this weakening can "strongly rebound" and produce higher protective antibodies.
