Influvac- TETRA

Influvac® TETRA is a quadrivalent, inactivated influenza vaccine manufactured by Abbott India Limited. Designed as a 0.5 ml suspension for injection, it contains purified surface antigens from four distinct influenza virus strains—typically two influenza A subtypes and two influenza B lineages—to provide comprehensive seasonal protection. By introducing inactivated surface antigens, the vaccine safely stimulates the body’s immune system to produce targeted antibodies without causing the flu itself. It is widely utilized in clinical settings to prevent seasonal influenza, effectively reducing the risk of viral transmission, flu-related complications, and hospitalization across vulnerable populations.
