How much is the cost of the third injection of COVID-19? Is the COVID-19 vaccine lifelong immunization

How much does COVID-19 vaccine cost for one shot

Vaccination is free for all people. The recommended immunization program is to receive two doses, with an interval of 14-28 days between each dose. The vaccination site is the deltoid muscle of the upper arm. Adjusting the immunization program arbitrarily may affect safety, immune response effectiveness, and immune persistence. At present, it is necessary to wait for local units to notify the key defense population according to national requirements and the supply of vaccines in each province, and then go to licensed formal vaccination units for vaccination, which is not yet open to the public.

Is COVID-19 vaccine lifelong immune

No. Vaccination can only reduce the risk of infection. If you are exposed to an environment full of COVID-19 virus, you may also be infected, but the probability of infection is lower than that without COVID-19 vaccine. In addition, the research and development time of the COVID-19 vaccine currently vaccinated is relatively short, and it is difficult to specify its validity period accurately now. However, after COVID-19 vaccine inoculation, you can protect it for at least more than half a year, and the specific length of time is still unknown.
