HepA-L

HepA-L is a live attenuated hepatitis A vaccine used to prevent infection by the hepatitis A virus (HAV). Unlike inactivated vaccines, HepA-L contains a weakened form of the virus that stimulates an immune response without causing disease. Both inactivated (HepA-I) and live attenuated (HepA-L) hepatitis A vaccines are highly immunogenic and well tolerated, providing long-lasting immunity for at least 20 years post-vaccination. The vaccine is effective for both preexposure and postexposure prophylaxis, especially among children and young adults. It works by inducing the body to produce antibodies against HAV, conferring protection against future exposures[8][10]. Live attenuated HepA vaccines are not available in all countries; for example, they are not licensed in the United States but may be used elsewhere.
