Which flu vaccine is better?
If we had to answer, we’d say both are good! But let’s see how the 3-strain and 4-strain flu vaccines differ.

### **3-Strain vs. 4-Strain Influenza Vaccine – What’s the Difference? **
**3-Strain Vaccine** – Protects against **2 strains of Influenza A** + **1 strain of Influenza B**
**4-Strain Vaccine** – Protects against **2 strains of Influenza A** + **2 strains of Influenza B**
**Key Difference:** Both vaccines contain the same components, but the **4-strain vaccine includes an additional B/Yamagata strain.**
**Annual updates**: The influenza vaccine formula is adjusted each year to match circulating virus strains. It is recommended to **get vaccinated once a year** to maintain immunity!
However, **WHO experts** have noted that **the B/Yamagata strain has not been detected for over four years**, making its risk very low. As a result, it **may no longer be necessary** to include this strain in future vaccines, meaning influenza vaccines **could revert to a 3-strain composition.**
**The World Health Organization (WHO) and the Ministry of Public Health recommend annual flu vaccination** as influenza viruses continuously evolve. The vaccine formulation is updated yearly to match circulating strains. Since influenza has a **short incubation period**, maintaining **high immunity levels** is essential for protection, making **annual flu vaccination necessary.**
**Who can get vaccinated?**
Anyone **6 months and older** can receive the flu vaccine—**even if you don’t have any underlying conditions!**
Stay healthy—prevention is always better than cure!
