How Nasovac Injection works

Nasovac Injection is a combination of two medicines: Inactivated influenza vaccine and Sorbitol. Inactivated influenza vaccine is a vaccine which helps develop immunity by initiating a mild infection. This type of infection does not cause illness but stimulates the body's immune system to produce antibodies (proteins) to protect against any future infections. Sorbitol is a preservative.

Quick tips

Let your doctor know if you have ever had a serious reaction to any vaccine, especially a flu shot or ingredients like egg or sorbitol.
You might feel mild fever, soreness, or body aches after receiving Nasovac Injection, as this is normal and usually goes away in a day or two.
Avoid heavy exercise for a few hours after getting Nasovac Injection to reduce the chances of arm pain or swelling.
Keep the injection area clean and avoid scratching it if it feels itchy.
If you experience trouble breathing, hives, or swelling of the face soon after the injection, seek medical help immediately. These could be signs of an allergic reaction.
