WHO predicts that India would reach record DPT3 immunisation coverage in 2022

  • In 2022, India’s coverage rate for DPT3 vaccines (diphtheria, pertussis, and tetanus) achieved an all-time high of 93%, breaking the pre-pandemic record of 91% in 2019.
  • The World Health Organisation (WHO) reported this huge growth from 85% coverage in 2021.

What is DPT3?

DPT3 vaccinations are a three-in-one vaccine that protects against three infectious diseases: diphtheria, pertussis (whooping cough), and tetanus.

The “DPT” in DPT3 stands for the initials of these three diseases:

  • Diphtheria is a bacterial infection that mostly affects the lungs. It can cause severe throat and nasal congestion, breathing difficulties, and, in severe cases, heart and nerve damage.
  • Pertussis is a highly contagious respiratory infection caused by the bacteria Bordetella pertussis. It is distinguished by intense coughing episodes, which are frequently accompanied by a “whooping” sound when gasping for breath. Infants and small children are especially vulnerable to pertussis.
  • Tetanus: A bacterial infection caused by the bacterium Clostridium tetani, often known as lockjaw. It enters the body through wounds or cuts and creates a toxin that affects the neurological system, causing muscle stiffness and spasms, notably in the muscles of the jaw and neck.

WHO immunisation records

  • DPT3 Coverage Recovery: DPT3 coverage in the WHO South-East Asia Region recovered to pre-pandemic levels of 91% in 2022, up from 82% in 2021.
  • Measles Vaccine Coverage: The region’s measles vaccine coverage increased by 6%, climbing to 92% in 2022 from 86% in 2021.
  • Zero-Dose Children: From 4.6 million in 2021 to 2.3 million in 2022, the number of zero-dose children (those who have not gotten even the first dose of the DPT vaccination) has been cut in half.
  • Partially Vaccinated Children: From 1.3 million in 2021 to 650,000 in 2022, the number of partially vaccinated children (those who received at least one dose but not the entire three-dose series) declined.
