After receiving the first two doses of Beijing Coxin CWV New Coronavirus Vaccine, it is recommended to receive the third dose of New Coronavirus Vaccine if you have reached the age of 18 years old (relaxed to 12 years old in some areas) and there are no other contraindications to New Coronavirus Vaccine vaccination, and you have been vaccinated for 6 months. The new coronavirus vaccine is an inactivated vaccine. The protective effect of the vaccine will decrease over time after the two basic shots. According to existing domestic and international studies on the protective effect of the new coronavirus vaccine, booster vaccination can extend the protection time and improve the protective effect of the vaccine, and can also significantly increase the level of corresponding antibodies against the new coronavirus in the human body. In view of the current epidemic situation, receiving a booster shot of the New Crown vaccine can reduce the risk of disease after infection and provide further protection for one’s health. A third booster is recommended if it has been six months since the first two doses, if the patient’s age and physical condition meet the conditions for vaccination, and if there are no contraindications to vaccination.
