Influenza Vaccine

The Influenza Vaccine is given to protect you and your loved ones from infections caused by the influenza virus. Some of the symptoms of the flu are fever, cold, runny nose, etc. This vaccine is given to minimise the complications of respiratory infections. 


It is administered by the nurse at the health centre by checking the patient and calculating the dose required on the basis of age. The patient is then instructed on the side effects of the shot. This vaccine reduces the risk of infection by 40%-60%.

How Much Does the Influenza Vaccine Cost in India?

In India, the influenza vaccine price ranges from around ₹800 to ₹1,500 per shot. According to reports, the cost can be more than that as well when it comes to flu shots. The influenza vaccine covers diseases like swine flu, seasonal flu, and other types of influenza. 


In recent times, the number of people taking the influenza vaccine has gone high and according to various reports, this is mainly due to the COVID-19 pandemic. However, the flu vaccine need not be mandatorily taken in India.

Why is the Influenza Vaccine Given?

The flu vaccine is usually given because the flu is infectious and can cause severe respiratory infections. Typically, the flu is confused with the common cold. The common cold is not particularly extreme and lasts only up to a few days. 


On the other hand, the flu can cause severe symptoms and can stay for a prolonged period. In addition to these flu infections, superinfections may also occur in some cases. Superinfections are essentially bacterial infections that are followed by a respiratory infection. So, to stay protected from such illnesses and their dire side effects, flu shots are administered.
