sabin-strain inactivated poliovirus vaccine + hepatitis A live attenuated vaccine

This product is a **combination vaccine** containing **Sabin-strain inactivated poliovirus vaccine (sIPV)** and **hepatitis A live attenuated vaccine**. - **Sabin-strain inactivated poliovirus vaccine (sIPV):** An inactivated (killed virus) vaccine derived from the attenuated Sabin strains of poliovirus, developed to provide immunity against poliomyelitis without the risk of vaccine-associated paralytic poliomyelitis. sIPV works by stimulating the immune system to produce neutralizing antibodies (IgG) against poliovirus types 1, 2, and 3[1][2][4][5]. The Sabin strains, originally developed for oral vaccines, are used inactivated in this formulation, reducing biosafety risks and avoiding transmission through fecal shedding[5]. - **Hepatitis A live attenuated vaccine:** A vaccine containing live, weakened hepatitis A virus that stimulates cellular and humoral immunity for long-term protection against hepatitis A infection. The vaccine is primarily indicated for **protection against both poliomyelitis and hepatitis A**. It is used in populations where combined prevention is needed, such as pediatric immunization programs.
