Clinically infants are not eligible for the Neocoronavirus vaccine. Currently, China has approved the use of the inactivated New Crown virus vaccine for ages 3 years and older, and it is not recommended for infants and children under the age of three. At present, as the effects of the vaccine are still uncertain, due to the fact that infants have poor resistance and are in the stage of growth and development, the vaccination of the new crown vaccine may cause adverse reactions and have an impact on their health, so it is not recommended. During the outbreak, try to avoid taking infants to crowded places to avoid increasing the risk of infection. Infants need to clean their hands thoroughly when they go out and come home, before wearing masks and after removing masks or after contacting potentially contaminated items, and avoid dirty hands touching the mouth, eyes and nose areas.
