Covid-19 may have mysteriously spared kids from severe infection but it led to major backsliding on childhood vaccinations as has been revealed by a new UNICEF report released on Thursday. It warned that India is home to about 2.7 million of the world’s zero-dose children despite it being among only three countries out of 55 where the perception of the importance of vaccines held firm or improved after the pandemic. Zero-dose children are those who have not received a single routine vaccine.
On a positive note, The UNICEF’s ‘The State of the World’s Children - 2023’ said that nevertheless, India was able to arrest the backslide between 2020 and 2021 to bring the number of zero-dose children down to 2.7 million thanks to unwavering political commitment and sustained evidence-based catch-up campaigns initiated by the government, including the fourth Intensified Mission Indradhanush (IMI) and its continued provision of comprehensive Primary Health Care services.
Flagging concerns about potential polio and measles outbreaks, the report warned that 67 million children across the globe missed out on vaccinations between 2019 and 2021 with the coverage levels declining in 112 countries. In 2022, the number of measles cases was more than double the previous year’s total. The number of children paralysed by polio was up 16 per cent on-year in 2022. Of the 67 million children whose vaccinations were “severely disrupted,” 48 million missed out on routine vaccines entirely.
When comparing the 2019-to-2021 period with the previous three-year block, there was an eight-fold increase in the number of children paralysed by polio, highlighting the need to ensure sustained vaccination efforts.
“This data is a worrying warning signal. We cannot allow confidence in routine immunizations to become another victim of the pandemic.
“Otherwise, the next wave of deaths could be of more children with measles, diphtheria or other preventable diseases,” said UNICEF Executive Director Catherine Russell.
“For every child, vaccination reveals the perception of the importance of vaccines for children declined by more than a third in South Korea, Papua New Guinea, Ghana, Senegal and Japan after the start of the pandemic,” the UNICEF report said.In the new data -- collected by The Vaccine Confidence Project and published by UNICEF -- China, India and Mexico were the only countries studied where the data indicated that the perception of the importance of vaccines held firm or even improved.
The report said that vaccine confidence is volatile and time specific despite more than 80 per cent of the respondents perceived vaccines as important for children in almost half of the 55 countries studied.
However, the report warns that the confluence of several factors suggests the threat of vaccine hesitancy may be growing. These factors include uncertainty about the response to the pandemic, growing access to misleading information, declining trust in expertise and political polarisation.
