There is also a risk of contracting the new coronavirus after three vaccinations.
Since the New Crown vaccine is not a lifelong immunization, two doses of inactivated New Crown vaccine will stimulate the body to produce immunity and antibodies. As the antibody titer decreases over time, a booster shot six months after the second dose of New Crown vaccine will stimulate the body to produce an immune response again and increase the level of antibodies in the body.
Although vaccination with the New Crown vaccine provides immunity to the majority of the population and effectively reduces the incidence of the disease, the vaccine’s protective effect is not 100% and there is still a possibility of contracting New Crown pneumonia. People who complete all three doses of the vaccine are significantly less likely to develop CKP and have a lower mortality rate after the onset of the disease than those who do not complete the CKP vaccine.
It is recommended that, in the absence of special circumstances, timely vaccination, good protection, hand hygiene and disinfection can effectively reduce the chances of infection.
Tip: In this article, the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
