Influenza is an airborne infection. It can spread from person to person via coughing, sneezing, and touching infected surfaces. You should consult with the best pulmonologist in Bangalore regarding these respiratory issues.

Is Influenza the same as the common cold?

No, the symptoms of influenza are more severe as compared to that of the common cold. Moreover, a common cold does not cause serious health problems whereas influenza does.

Who is eligible to get the Influenza vaccine?

Everyone above the age of 6 months is eligible. However, it is recommended that high-risk individuals speak to their doctor about getting vaccinated.

Does the vaccine have side effects?

If you get any reaction following your Flu vaccination: Do’s and Don’ts


If you get any reaction following your Flu vaccination
Do's Dont's
Expect mild side-effects of soreness, redness, swelling, low-grade fever, headache or muscle aches 1-2 days after getting vaccinated. All this usefully settles down on its own Self-medicate if you feel unwell after the shot.
Keep yourself hydrated. Apply any ointment or patches at the injection site.
Reduce fever with a cool sponge bath. Massage the injection site.
Consult your doctor if you want to take pain-killers for pain or fever. Forget to keep your vaccination record safe for future reference, including the history of reaction.
Try moving your arm around to help relieve pain and swelling. Skip your regular doctor visit if you are suffering from chronic diseases such as diabetes, etc.
Apply cool, wet washcloth or ice if you experience soreness at the site of injection. Forget to wear a mask and maintain social distancing while stepping out of the house as the Flu shot does not afford protection against COVID 19.
Contact your doctor if you experience an allergic reaction or any serious side-effects post-vaccination such as rashes, breathlessness, muscle weakness, giddiness or vomiting.  
Expect the flu vaccine to afford protection only after 14 days post-immunization.  
Eat a healthy balanced diet and exercise regularly to boost immunity.  
Maintain personal hygiene.
