VACCINE SHORTAGES AND MISSED OPPORTUNITIES FOR VACCINATION IN CHILDREN
AGED <5 YEARS
Jose-Luis Diaz-Ortega
National Institute of Public Health, Mexico
Introduction:
Missed opportunities for vaccination (MOV) are defined as non-application of one or more vac-
cine doses to eligible population for vaccination during a contact with health facilities. Because immunization
coverage in some districts of the state of Oaxaca, Mexico is not optimal, author investigated the factors associ-
ated with MOVs, in children aged <5 years.
Methods:
They performed a cross-sectional study in health facilities of two sanitary districts and interviewed
the caregivers of 837 children who few minutes ago, had visited health facilities. Vaccines not applied to eligi-
ble children during this visit were considered MOVs. They estimated frequency of MOVs, as well as crude and
adjusted odds ratios (ORs) to analyze factors associated with MOVs.
Results:
Shortage of some vaccines was the main factor associated to MOV. Risk of MOVs was higher in children
aged 1-4 years, than in children aged <1 year (OR 10.0, p=0.001). Children visiting health facilities for reasons
different to vaccination had higher risks of MOVs than those who went for vaccination (OR 2.4, p=0.0001).
Conclusions:
Major causes of MOVs were vaccine shortages, false contraindications and failure of health per-
sonnel to review children’s immunization cards.
