A newborn is defined as from birth to within twenty-eight days. Newborns are immunized with BCG and Hepatitis B vaccines.
1. BCG: BCG is a live attenuated vaccine, usually inoculated within 24 hours of the birth of newborns, if because of premature birth, disease and other reasons did not get vaccinated in time, you can be vaccinated within 3 months, more than 3 months to 3 years between the tuberculin test, negative can be vaccinated.
BCG vaccine can prevent neonatal heavy tuberculosis – disseminated tuberculosis and tuberculous meningitis, which can reduce the probability of serious tuberculosis and reduce neonatal mortality.
2. Hepatitis B Vaccine: Hepatitis B vaccine is given in 3 doses, the first dose is given within 24 hours of birth, the second dose is given at the end of the first month, and the third dose is given at 6 months of age.
The reason why hepatitis B vaccine is given to newborns at birth is that newborns are not immune to hepatitis B virus and their immune function is not yet sound, so once they are infected with hepatitis B virus, they will become hepatitis B virus carriers. Most hepatitis B virus surface antigen carriers originate from mother-to-child transmission and early childhood infections, so the sooner a newborn is vaccinated within 24 hours of birth, the better.
Vaccination is an effective means of disease prevention for newborns, and it is important to immunize newborns on time to ensure normal growth and development.
