National Vaccination Day is celebrated every year on 16 March across the country to spread awareness about the importance of vaccines in human health. It highlights the importance of vaccines to fight deadly diseases and acknowledges and appreciates the hard work of doctors, frontline health care workers to ensure that every child is immunised.
Immunization is an important aspect of public health. Vaccines provide immunity to the body against future encounters with the same pathogen. They have reduced the spread of many deadly diseases such as measles, chicken pox, tetanus, rubella, polio and more recently COVID-19.
The first dose of oral polio vaccine was given in India on March 16, 1995. Thus, National Immunization Day celebrates the beginning of the pulse polio program of the government which helped in eradicating polio from the country.
