Why do you want to inoculate Handan booster needle? (attention! Many places in Hebei can get booster shots)

Handan City has started the intensified immunization of COVID-19 vaccine. According to the unified deployment of the leading group for the response to the novel coronavirus epidemic in Hebei Province, in order to further enhance the immune effectiveness of the vaccinated population in COVID-19 and consolidate the immune barrier, our city has started to strengthen the immunization of all people aged 18 and above, and vaccinated COVID-19 inactivated vaccine and adenovirus vector vaccine for 6 months, with free vaccination 1 dose.

At present, the global COVID-19 epidemic continues, and China is still under great pressure of "preventing imports from outside and rebounding from inside". Up to now, more than 40,000 doses of COVID-19 vaccine/KLOC-0 have been inoculated in Handan. COVID-19 vaccine is effective in preventing COVID-19 infection and re-transmission, especially in preventing severe illness and death. Urban and rural residents aged 65, 438+08 and above who have been vaccinated with inactivated vaccine and adenovirus vector vaccine in COVID-19 for six months shall choose the nearest vaccination unit to carry out COVID-19 vaccine booster immunization with vaccination certificate, ID card and QR code of vaccination program. Here, we expect you to start from "me" as always, and encourage everyone around you, such as family, friends and colleagues, to do something actively: get COVID-19 vaccine as soon as possible. Vaccination with COVID-19 vaccine is the most economical and effective means to prevent COVID-19. * * * Building the Great Wall of Immunization needs your help.

Why should I get a booster shot? What is the effect after vaccination?

From the existing observation and research, COVID-19 vaccine has a remarkable effect in preventing severe illness and death after the whole vaccination. However, after inoculation for a period of time, the immunity of some people decreased and the protective effect weakened. A booster vaccine can make this weakening "strongly rebound".

According to some data, the antibody level increased by more than 10 times after the second dose of domestic inactivated vaccine was inoculated for half a year.

The results of intensive immunization study of inactivated vaccine in COVID-19 carried out by related enterprises showed that the antibody of inactivated vaccine in COVID-19 decreased in different degrees after 6 months of inoculation, which was the same as that after routine inoculation. After intensive immunization, the antibody level of the recipient will rise or rebound rapidly. After 14 days of intensive immunization, the antibody level was equivalent to the original 10-30 times. After 6 months, although the antibody level also decreased, it was still higher than the peak after two doses of inoculation or 1 dose, which could maintain a high level and had a good cross-neutralization effect on mutants such as Delta.
