About Inactivated Hepatitis A Vaccine
Inactivated Hepatitis A Vaccine belongs to the class of medication called 'biologics vaccines' or 'immunising agents' used to prevent hepatitis A infection.

Hepatitis A is a vaccine-preventable liver infection caused by the hepatitis A virus (HAV) spread by contaminated food or water and contact with infected persons.
Inactivated Hepatitis A Vaccine contains Hepatitis A antigen virus (Inactivated). It aids in the development of immunity by producing antibodies, which are proteins that protect against infection induced by viruses in the vaccine. A booster dose must be taken at the doctor's discretion for long-term protection.
Inactivated Hepatitis A Vaccine should be given by a trained healthcare professional. Inactivated Hepatitis A Vaccine may cause side effects such as pain and discomfort at the injection site, nausea and low-grade fever. These side effects are usually mild and temporary.

Uses of Inactivated Hepatitis A Vaccine
Medicinal Benefits
Inactivated Hepatitis A Vaccine contains ‘Hepatitis A antigen virus (Inactivated)’, which can effectively prevent hepatitis A infection if given within two weeks post-exposure. Its use is recommended for children aged less than 12 months, people who are allergic to the vaccine or vaccine component or decreased response to the vaccine, who are travelling to an area where hepatitis A is endemic (prevalent in that region), who have weak immune systems such as with HIV, and who are at risk of long-term conditions of the liver such as hepatitis B or C infection. It helps to prevent infection in the household or other close contacts such as a person living in the same household as the infected patient, a person who had sexual contact with the infected person, child-care staff or a person who is taking care of an infected child, healthcare professionals administering injections to the infected person and persons living in long-stay care facilities which are sharing toilets or other facilities with the infected person.

FAQs
Inactivated Hepatitis A Vaccine contains Hepatitis A antigen virus (Inactivated). It aids in the development of immunity by producing antibodies, which are proteins that protect against infection induced by viruses in the vaccine. For long-term protection, a booster dose must be taken at the discretion of the doctor.
Taking live vaccines such as MMR (measles, mumps, and rubella) and varicella (chickenpox) vaccines within 3 months of taking Inactivated Hepatitis A Vaccine is not recommended. Inactivated Hepatitis A Vaccine may alter the action of these vaccines, making them less effective.
The hepatitis A vaccine stimulates the immune system to produce antibodies against the hepatitis A virus (HAV) and provides long-term protection against the virus. On the other hand, hepatitis A immunoglobulin contains antibodies that act against HAV and is given when immediate protection against the virus is needed.
Hepatitis A, Hepatitis B and Hepatitis C are three different viruses that cause severe liver infection. Though each virus of hepatitis can cause similar symptoms, they are spread in different ways and can affect the liver differently. Hepatitis A causes short-term infection. While Hepatitis B and C can begin with short-term infections, in some cases, can cause chronic or lifelong infections. There are vaccines to prevent hepatitis A and hepatitis B, but no vaccine is available for hepatitis C.
Inactivated vaccinations are another type of vaccine in which the virus is inactivated during manufacturing.
Inactivated Hepatitis A Vaccine should be stored in a refrigerator (between +2°C and +8°C). Do not freeze; destroy the Inactivated Hepatitis A Vaccine if it has been frozen.
