Adult Immunisation- What should I know about Influenza vaccination

Vaccination is the most cost effective strategy in public health today. It not only protects the individual from contracting a particular disease, which may be community acquired; but it also protects the community from the spread of the infection. 

The most famous example known to the world is small pox. And more recently, in India, polio. 


Although adults are less prone to develop the traditional infectious diseases, owing to better immunity compared to children, owing to globalisation and increasing travel oppurtunities, the world has become a smaller place. Hence, the risk and incidence of exposure to various agents are increased many fold. 

 So, as we celebrate the Adult Immunisation Week, let us focus on a few vaccines which should be routinely taken by adults. 


Influenza is commonly known as flu and is caused by influenza type A and type B viruses. 


  • Persons with chronic medical illness like chronic kidney disease, asthma, chronic lung disease, immunocompromised individuals 
  • Pregnant women
  • Adults > 65years of age 


  • Annually (Every year), 0.5 ml of the vaccine to be taken as an injection intra dermally (into the skin) or intra muscularly (into the muscle)
