Can I go to COVID-19 Vaccination Enhancement Center without an appointment?

The booster needle generally refers to COVID-19 vaccine booster needle, and COVID-19 vaccine booster needle can be used directly without reservation.

COVID-19 vaccine booster is suitable for people who have been vaccinated with inactivated vaccine or Kangxinuo vaccine for more than six months. You can usually go directly without an appointment. COVID-19 vaccine fortifier mainly improves vaccine protection efficiency and prolongs vaccine protection time. Generally, COVID-19 vaccine can not achieve the effect of lifelong immunity. According to relevant clinical trials and studies, the protection period of COVID-19 vaccine is at least half a year, and the specific length of individuals varies. Therefore, usually after the second dose of COVID-19 vaccine or Kangxinuo vaccine is inoculated for half a year, the titer of specific immune antibody produced in the body may also decrease in different degrees, and the protection efficiency of the vaccine will also decrease. In order to improve the protection efficiency of the vaccine, some people can increase the titer of immune antibodies by vaccinating COVID-19 vaccine booster again, thus further reducing the risk of COVID-19 infection. However, even after the vaccination in COVID-19, you still need to take personal protective measures and wear a mask when you go out.
