There are some vaccines that are mandatory for babies from birth to within 6 years of age, such as the above five vaccines, and in some areas, there are also additional vaccines such as Rheumatoid Vaccine and Encephalitis B Vaccine. These are mandatory vaccines for babies and should be completed within the prescribed vaccination schedule according to the immunization program. As for the new crown vaccine, it is currently recommended to exclude contraindications to universal on-time vaccination; for the existence of rabies secondary or tertiary exposure of patients should be completed in time for rabies vaccination; HPV vaccine is not a mandatory vaccine for the time being, and those who wish to do so can exclude contraindications to be vaccinated.
