Introduction to Havrix 720 Injection
Havrix 720 injection is an antiviral drug belonging to the class of inactivated vaccines containing the active ingredient Hepatitis A Vaccine. It can be mainly used for the prevention of hepatitis A virus infection. Hepatitis A infection is due to a virus that attacks the liver. It may be caught from food or drink that contains the virus. Vaccines are used to protect you against infectious diseases. This vaccine helps to protect against hepatitis A infection in people 16 years of age and older.Â
This vaccine is generally safe for immunocompromised individuals, including those with HIV infection or other conditions that weaken the immune system. However, their immune response to the vaccine may be diminished, reducing protection. In such cases, a healthcare provider may consider additional doses or antibody testing to assess vaccine effectiveness. If you or your child are scheduled to receive multiple vaccines, it's always a good idea to discuss the vaccination plan with your healthcare provider.
Individuals with a known severe allergic reaction (anaphylaxis) to a previous dose of this vaccine or any of its components should not receive the vaccine. It's important to inform your healthcare provider about any allergies or previous adverse reactions before getting vaccinated. The Havrix 720 injection is safe for pregnant and breastfeeding women.
