Vaccination uses your body’s natural defences to build resistance to specific infections and strengthens your immune system. They train your immune system to create antibodies, just as when exposed to a disease.
Dr Amitoj Singh Chhina, Consultant- Pediatrics and Neonatology, Cloudnine Group of Hospitals, Bengaluru (Old Airport Road), explains that protecting ourselves and those around us are two key reasons to get vaccinated.
Flu infects hundreds of thousands of people in our country every year, leading to tens of thousands of hospitalisations and deaths. It is particularly devastating among vulnerable populations like the elderly and young children.
If a person received the flu vaccine last year, it can't provide enough protection this year because flu viruses can change. The vaccine must be updated yearly to include the most current virus types.
Sometimes the same virus types are included in the vaccine yearly. Even then, the yearly flu vaccine is still essential because the body's immunity against the influenza virus declines over time.
Getting the flu vaccine protects the recipient and helps protect the community. As immunisation makes someone less likely to get the flu, they are less likely to spread it. It's the only way to protect infants younger than six months from the flu, as they cannot receive the vaccine.
Vaccines are safe, support your immune system and can prevent serious illness
Vaccines may be required for different age groups like children, the elderly and now for travel.
