India achieves record DPT3 vaccination coverage in 2022: WHO


From UPSC perspective, the following things are important :

Prelims level: DPT3

Mains level: Not Much


Central Idea

  • The coverage rate for DPT3 vaccines (diphtheria, pertussis, and tetanus) in India reached an all-time high of 93% in 2022, surpassing the pre-pandemic record of 91% in 2019.
  • This significant increase from the 85% coverage in 2021 was reported by the World Health Organization (WHO).

What is DPT3?

  • DPT3 vaccines refer to a combination vaccine that provides protection against three infectious diseases: diphtheria, pertussis (whooping cough), and tetanus.
  • The “DPT” in DPT3 stands for the initials of these three diseases:
  1. Diphtheria: It is a bacterial infection that primarily affects the respiratory system. It can cause severe throat and nose congestion, difficulty breathing, and in severe cases, it can lead to heart and nerve damage.
  2. Pertussis (Whooping Cough): It is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. It is characterized by severe coughing fits, often accompanied by a “whooping” sound when gasping for breath. Pertussis can be particularly dangerous for infants and young children.
  3. Tetanus: Also known as lockjaw, is a bacterial infection caused by the bacterium Clostridium tetani. It enters the body through wounds or cuts and produces a toxin that affects the nervous system, leading to muscle stiffness and spasms, particularly in the jaw and neck muscles.

WHO records on immunization

  • DPT3 Coverage Recovery: The WHO South-East Asia Region saw the DPT3 coverage recover to pre-pandemic levels of 91% in 2022, a significant increase from 82% in 2021.
  • Measles Vaccine Coverage: The region also witnessed a six percent improvement in measles vaccine coverage, rising to 92% in 2022 from 86% in 2021.
  • Zero-Dose Children: The number of zero-dose children (those who have not received even the first dose of the DPT vaccine) halved from 4.6 million in 2021 to 2.3 million in 2022.
  • Partially Vaccinated Children: The number of partially vaccinated children (those who received at least one dose but not the complete three-dose series) decreased from 1.3 million in 2021 to 650,000 in 2022.
