The coverage rate for DPT3, the third dose of diphtheria, pertussis and tetanus vaccines, in India rose to an all-time of 93% in 2022, surpassing the previous pre-pandemic best of 91% recorded in 2019, and also marking a sharp increase from the 85% recorded in 2021, the World Health Organization (WHO) said.

• The WHO and UNICEF estimates for national immunisation coverage for 2022, released on July 18, showed that in the WHO South-East Asia Region, the coverage rate for DPT3 recovered to the pre-pandemic level of 91%, a sharp increase from the 82% recorded in 2021.  
• The region also witnessed a six per cent improvement in the coverage of the measles vaccine, rising to 92% in 2022 from 86% in 2021.  
• In this 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. 
• Similarly, the number of partially vaccinated children (those that have received at least one dose of DPT vaccine but did not complete the primary series of three doses) reduced to 6,50,000 in 2022 from 1.3 million in 2021.
