🔥 UNDERSTANDING THE QUADRIVALENT (4-STRAIN) & TRIVALENT (3-STRAIN) INFLUENZA VACCINES, WHICH ONE SHOULD YOU CHOOSE?
Respiratory illnesses are on the rise, and the demand for flu vaccinations has significantly increased. Consequently, VNVC has been receiving numerous inquiries about what the 3-strain and 4-strain flu vaccines are, why their prices vary, and which one to choose.
👉 According to experts, the trivalent influenza vaccine covers 3 strains of the flu virus, including 2 strains of influenza A (H1N1 and H3N2) and only 1 strain of influenza B (either Victoria or Yamagata). Meanwhile, the quadrivalent influenza vaccine covers 4 strains, including 2 strains of influenza A (H1N1, H3N2) and 2 strains of influenza B (Yamagata, Victoria).
Vietnam currently has two types of trivalent and quadrivalent flu vaccines with differences in cost, manufacturers, and coverage:
Trivalent flu vaccine (protecting against 3 flu strains): Ivacflu-S (Vietnam).
Quadrivalent flu vaccine (protecting against 4 flu strains): Vaxigrip Tetra (France) and Influvac Tetra (Netherlands).
Experts note that all flu vaccines are effective in preventing seasonal flu with good safety and immune response. However, based on the level of protection, the QUADRIVALENT FLU VACCINE contains antigens from both influenza A and B viruses, providing protection against all 4 strains of flu. In contrast, the TRIVALENT FLU VACCINE covers only 1 strain of influenza B.
