What is a flu shot?
Flu is a highly contagious health issue that affects millions of people every year. It hits during the late summers and early monsoon months causing cold, cough, fever, body ache, etc. issues. While flu is touted to be easily treated through medications, it is better to get flu shots to prevent serious repercussions. Besides, we are already dealing with the deadly covid pandemic that compromises immunity and allows Influenza virus to easily attack the body. This affects the entire respiratory system of the body including nose, throat and lungs.
Why is getting a yearly flu shot important?
The flu variant keeps changing every year which warrants a flu shot yearly. It basically prevents diseases because of influenza, which can be very nasty and can cause severe respiratory compromise in patients especially in elderly ones. But we have seen patients who are relatively young without any comorbidities coming in with severe lower respiratory tract infection. Taking a flu shot every year would protect against flu and other infections caused by the Influenza virus.

Types of Flu Shot
There are two types of influenza flu shots- Intranasal vaccine and Injectable vaccine.
Intranasal vaccine is sprayed into the nostrils. This vaccine produces mucosal immunity as well as antibodies that spread throughout the body through blood. Since the flu-causing virus mainly enters through the nose and mouth, intranasal vaccine acts as the first line of defense. Thus, these provide better coverage as compared to injectable vaccines.
Dr. Agrawal recommends getting a flu shot as soon as it is available. It is better to get it in early summers before the onset of flu season for maximum protection.
