Is there a hepatitis B vaccine among preventive injections?
Generally, hepatitis B vaccine is one of the routine preventive vaccinations. The specific details are as follows:
Typically, a child's vaccination record lists nine vaccines: Bacillus Calmette-Guérin (BCG) vaccine, polio vaccine, diphtheria-tetanus-pertussis (DTP) combined vaccine, measles vaccine, mumps vaccine, rubella vaccine, hepatitis B vaccine, Japanese encephalitis vaccine, and meningococcal vaccine. The first dose of hepatitis B vaccine is usually administered within 24 hours after birth, followed by additional doses at 1 month and 6 months of age, for a total of three doses. The hepatitis B vaccine is used to prevent hepatitis B virus infection and has a relatively high efficacy.
It should be noted that if a liver function test reveals a decline in hepatitis B antibody levels, a booster dose of the hepatitis B vaccine can generally be given to increase antibody levels and enhance protection.
