Hepatitis A inactivated vaccine (human diploid cells)

Protection is achieved through the production of specific anti-HAV antibodies.

Inactivated Hepatitis A Virus

Active immunization of subjects at risk for hepatitis A virus infection.

1. For children aged 1-18, each dose is 0.5 ml, not less than 720 ELISA units; for children aged 19 and above, each dose is 1.0 ml, not less than 1440 ELISA units. 2. The basic immunization is a one-year dose, and a booster immunization is performed 6-12 months after the basic immunization to ensure that the antibody titer is maintained for a long time. 3. Both adults and children are injected intramuscularly into the deltoid muscle, and intravenous injection is never allowed. 4. It can be administered at the same time with many vaccines, such as: hepatitis B vaccine, cholera vaccine, tetanus toxoid, yellow fever vaccine, diphtheria toxoid, epidemic encephalitis vaccine, poliomyelitis vaccine (oral or intramuscular injection), rabies vaccine, etc. However, it should be noted that different injection equipment must be used at different sites. Different vaccines must not be mixed before injection.

Symptoms are mild and last no longer than 24 hours. Pain, nodules, redness and swelling at the injection site, systemic reactions include headache, fatigue, fever, nausea and loss of appetite.

Patients with acute, severe febrile illness.

Co-administration with immune globulin did not affect the seroconversion rate, but the HAV antibody titer was relatively lower compared with the vaccine alone.

Store at 2~8℃.

Each vial (bottle) contains 0.5ml. The dosage for children is 0.5ml per time, containing 250u of hepatitis A virus antigen.
