April 24-30 is World Immunisation Week and this year’s theme is Close The Immunization Gap.
Millions of kids each year get immunised to protect themselves against disease. Vaccines contain inactive viruses or bacteria that stimulate our body’s B and T immune cells to produce antibodies and prevent diseases. Getting vaccinated for different diseases confers what is called ‘acquired immunity to the disease. In public health practice, vaccination is given to confer community protection so that even unimmunized ones will have a reduced risk of acquiring the disease. This is called as the ‘herd effect’ of immunisation. But when only a few people are vaccinated the disease spreads easily to the population and leads to an outbreak . This video will tell you how vaccines work to protect the population.
