• Measles Supplemental Immunization Activities (SIAs) are resource intensive. • SIAs importantly reach some previously unvaccinated (so-called measles zero-dose) children. • We highlight difficulties in measuring how many measles zero-dose children the SIA reaches. • We also suggest some other methods to improve estimation of SIA impact.

Many measles endemic countries with suboptimal coverage levels still rely on vaccination campaigns to fill immunity gaps and boost control efforts. Depending on local epidemiological patterns, national or targeted campaigns are implemented, following which post-campaign coverage surveys (PCCSs) are conducted to evaluate their performance, particularly in terms of reaching previously unvaccinated children. Due to limited resources, PCCS surveys are designed to be representative at coarse spatial scales, often masking important heterogeneities in coverage that could enhance the identification of areas of poor performance for follow-up via routine immunization strategies.

: The Measles-Rubella Microarray Patch (MR-MAP) is an important technology that is expected to reduce coverage and equity gaps for measles-containing vaccines (MCVs), reach zero-dose children, and contribute to elimination of measles and rubella. MR-MAPs are anticipated to be easier to deploy programmatically and could be delivered by lesser-trained health workers, thereby increasing immunization coverage. The most advanced MR-MAP has reached clinical proof-of-concept through a Phase I/II trial in the target population of infants and young children.

Article Synopsis
- Only 23% of countries with recent supplementary immunization activities (SIAs) conducted post-campaign coverage surveys (PCCSs) to assess vaccination effectiveness, highlighting a significant gap in follow-up.
- Most PCCSs provided detailed sampling information, but the majority showed lower coverage levels than reported administrative data, raising concerns about data accuracy.
- Recommendations for improvement emphasize the need for more consistent and timely PCCSs across countries, especially within Gavi-eligible nations, to better identify and address measles immunity gaps.

Background: India has made exceptional advances in child immunisation, but subnational inequities in vaccination coverage impede attainment of key programmatic goals. Our study provides an up-to-date national portrait of local variations in child vaccination using a comprehensive set of indicators relevant to routine immunisation.
Methods: Indicators representing unvaccinated (zero-dose) children, incomplete basic immunisation, and vulnerability to measles and polio, were constructed from India's 2019-2021 National Family Health Survey.
In 2020, the World Health Assembly endorsed the Immunization Agenda 2030 (IA2030), a 10-year strategy to reduce vaccine-preventable disease (VPD)-associated morbidity and mortality. IA2030 goals include improving equitable vaccination coverage, halving the number of unimmunized (zero-dose) children, and increasing the introduction of new and underutilized vaccines. The COVID-19 pandemic disrupted health systems worldwide, hindering years of childhood vaccination achievements and putting global public health goals at risk.
