Why should we insist on vaccination? Here comes the key point

Vaccination

Accept all

Good hygiene habits and vaccination against the new coronavirus are the most effective means of personal protection.

It is very necessary to get vaccinated against the new coronavirus

Regarding the new coronavirus variants, relevant scientific research and epidemic prevention and control practices at home and abroad have shown that existing vaccines still have good preventive and protective effects:

How long does it take to produce antibodies after vaccination?

According to previous clinical trials of inactivated coronavirus vaccines, the vaccinated population can produce a better immune effect about two weeks after the second dose of the inactivated vaccine.

How long does immune protection last?

Data is still being collected on the duration of immune protection for the new coronavirus vaccine. Existing data shows that, like conventional vaccines, the antibody levels in the recipients will decrease over time after receiving the new coronavirus vaccine.

Six months after full immunization, the neutralizing antibody levels of people aged 18 to 59 and people over 60 in the target dose groups of various vaccines will drop by about 1.4 to 12.4 times. However, the decline in antibody levels does not mean that the vaccine's protective power does not exist. At what level will the protective power disappear? Data are still being collected for research.

After vaccination, personal protection is still required

Vaccination must be used together with strict prevention and control measures. At this stage, in order to ensure everyone's safety, after receiving the new coronavirus vaccine, everyone should continue to maintain personal protective measures, including wearing masks, maintaining social distance, washing hands frequently, and ventilating frequently.

■ For individuals, the protective effect of vaccination is not 100%, and it takes a certain amount of time to produce protective antibodies; for the group, the new coronavirus is still easily spread if an immune barrier is not formed.
