• 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.
