A booster shot is recommended at 6 months of age after completion of a single dose of the New Crown vaccine. The new coronary vaccine is an adenovirus-carrier vaccine. At present, booster shots can be given to people aged 18 years (relaxed to 12 years in some areas) and above who have completed one dose of adenovirus-carrier vaccine for 6 months, and who do not have any special health conditions. The booster shot of the new coronavirus vaccine mainly serves to raise the antibody titer in the body and enhance the prevention of the new coronavirus pneumonia. After a period of time, the antibody level in the body of an ordinary person will decrease after completing the full course of the new coronavirus vaccination. A booster shot of the new coronavirus vaccine can effectively raise the antibody level in the body and provide better protection against the mutated strain. It is recommended to consult a professional vaccination department about the booster shot after receiving a shot of the new crown vaccine from Concinol.
