Immunization efforts are hampered by enduring socioeconomic hurdles and regional inequities, which have a substantial influence on global health.
The most recent estimate of national immunization coverage (WUENIC) from the World Health Organization (WHO) and United Nations Children's Fund (Unicef) shows that 1.6 million children in India received zero dose vaccinations in 2023.
Along with Nigeria, Ethiopia, Congo, Sudan, Yemen, Indonesia, Angola, Pakistan, and Afghanistan, India is among the 10 nations with the lowest rates of mass immunization.
With 2.1 million unvaccinated youngsters in Nigeria in 2023, the country tops the list. The trend in India's neighborhood is somewhat better. During the time, Pakistan reported around 3,96,000 unvaccinated children, whereas Afghanistan recorded 4,67,000 in the same group.
According to the World Health Organization, children that are either uninitiated or do not get regular immunization programs are classified as zero-dose children.
Globally, there are 14.5 million "zero-dose" children who have not had any vaccinations, an increase of 1.7 million from 2019.
This suggests that there has been no appreciable shift in coverage from 2022, when the globe was still dealing with the effects of the Covid-19 epidemic. As of right now, performance is still below the 2019 levels, which serve as the baseline for the Immunization Agenda 2030.
Unvaccinated kids in emergency situations
The fact that the majority of zero dose children are from nations and territories with fragile, conflict-ridden, and vulnerable (FCV) environments is concerning.
31 nations with FCV settings are home to almost 55% of unvaccinated children, although making up just 28% of the world's birth cohort. Since 2019, there have also been concerning decreases in immunization rates in some of these nations. The number of children in each nation that are not vaccinated is reflected in the size of the bubbles.
holes in the measles vaccination
Furthermore, 55% of youngsters worldwide were not vaccinated against the measles in ten different nations. Moreover, three of them are among the ten nations with the lowest MCV1 coverage.
Approximately 1.6 million individuals in India are not in possession of a single dose of the measles vaccination. Only two nations, Nigeria and the Democratic Republic of the Congo, with 2.8 million and two million children respectively, lack the measles vaccination, after India. On the list, neighboring nations like Pakistan and Afghanistan are ranked higher with 1.1 million and 6,37,000, respectively, "measles zero dose children."
rise in HPV vaccination coverage
However, the coverage of the HPV vaccination deviates from this pattern. In numerous countries, its coverage has almost returned to its pre-pandemic level, and 37 nations—both higher- and lower-income—have begun using single-dose schedules.
Girls' HPV coverage has grown globally, mostly as a result of new initiatives and program expansions as well as positive indicators of coverage recovery in already-existing programs.
Continued high dropout rate
According to the survey, almost 13% of children do not complete the necessary timetable, leading to a high percentage of dropouts.
The Americas area is the only one to surpass the year-end goals for performance. Zero-dose youngsters are over their goal trajectory in every other location. According to Immunization Agenda 2030, every nation must cut in half the percentage of children receiving zero doses in 2019 by the year 2030.
It is imperative that the nations understand, nevertheless, that complete immunization is not ensured by a singular concentration on the zero dose (DTP1). The individual may still be susceptible to additional antigens, for which a strong immunization campaign is essential.
