Why in News?

In a joint press release, the World Health Organization (WHO) and United Nations Children's Fund (UNICEF) announced that significant progress had been made in global immunization efforts during 2022.

  • Over 4 million more children were vaccinated in 2022 compared to the year before, reflecting the collective efforts of countries and international organizations to combat vaccine-preventable diseases.

What is the Major Progress in Global Immunization Efforts?

  • Positive Trends in Immunization Coverage:
    • DTP3 Vaccine Usage as a Global Marker:
      • The DTP3 vaccine, protecting against diphtheria, tetanus, and pertussis (whooping cough), serves as the standard indicator for immunization coverage worldwide.
      • In WHO South-East Asia Region, the number of zero-dose children (those that have not received even the first dose of DPT vaccine) halved to 2.3 million in 2022 from 4.6 million in 2021.
      • The coverage rate for DPT3 in India rose to an all-time of 93% in 2022, surpassing the previous pre-pandemic best of 91% recorded in 2019.
    • Recovery from Pandemic-related Disruptions:
      • Of the 73 countries that experienced significant declines in immunization coverage during the pandemic, 15 have recovered to pre-pandemic levels and 24 are on the road to recovery.
    • HPV Vaccination Rates:
  • Lingering Disparities and Ongoing Challenges:
    • Uneven Recovery and System Strengthening:
      • While certain countries achieved remarkable recoveries, many smaller and poorer nations still face challenges in restoring immunization services.
      • 34 countries are stagnating or experiencing further declines in vaccination rates, underscoring the need for ongoing catch-up and system strengthening efforts.
  • Measles Vaccination: A Cause for Concern:
    • Measles (viral disease that typically affects children) vaccination rates have not rebounded as effectively as other vaccines.
      • This has increased the risk of measles infections for an additional 35.2 million children globally.
    • First dose measles vaccination coverage improved to 83% in 2022, but it remains lower than the 86% achieved in 2019.

What are the Major Global Initiatives Related to Immunization?

  • Immunization Agenda 2030 (IA2030): It sets an ambitious, overarching global vision and strategy for vaccines and immunization for the decade 2021–2030.
    • By the end of the decade, IA2030 aims to:
      • Reduce by 50% the number of children receiving zero vaccine doses
      • Achieve 500 introductions of new or under-utilized vaccines in low- and middle-income countries
      • Achieve 90% coverage for essential childhood vaccines
  • World Immunization Week: It is celebrated every year in the last week of April.
    • Theme 2023 - 'The Big Catch-up'

What is the Status of Immunization in India?

  • About:
    • Annually, India vaccinates more than 30 million pregnant women and 27 million children through its Universal immunization programme.
    • A child is considered fully immunized if they receive all the required vaccines as per the national immunization schedule within their first year of life.
      • However, according to UNICEF, only 65% of children in India receive full immunization during the first year of their life.
  • Major Immunization Programmes in India:
    • Universal Immunization Programme (UIP):
      • The program provides free immunization against 12 vaccine-preventable diseases.
      • Nationally Against 9 Diseases: Diphtheria, Pertussis, Tetanus, Polio, Measles, Rubella, severe form of Childhood Tuberculosis, Hepatitis B and Meningitis & Pneumonia caused by Hemophilus Influenza type B
      • Sub-nationally Against 3 Diseases: Rotavirus diarrhea, Pneumococcal Pneumonia and Japanese Encephalitis
      • Two major milestones of the UIP have been the eradication of polio in 2014 and the elimination of maternal and neonatal tetanus in 2015.
    • Mission Indradhanush:
      • Mission Indradhanush (MI) was launched by the Ministry of Health and Family Welfare (MOHFW) in 2014 with the aim to vaccinate all unvaccinated and partially vaccinated children under UIP.
        • It is being implemented in several phases.
    • Other Supporting Measures:
      • Electronic Vaccine Intelligence Network (eVIN) rollout.
      • National Cold Chain Management Information System (NCCMIS).
