Official title

Health Effects of Utilising Curative Health System Contacts to Provide Measles Vaccination - a Randomised Controlled Trial

Overview

In addition to protecting against measles infection, measles vaccine (MV) strengthens the individual's ability to combat infections in general - MV has beneficial non-specific effects (NSE) lowering the risk of death and admissions by around 30%. In Guinea-Bissau 30% of children do not receive a routine MV scheduled at 9 months of age, putting both the individual child's health and measles eradication at risk. The coverage of a second dose of MV, which was added to the Bissau-Guinean vaccination programme in 2022, is even lower. WHO recommends vaccination at health system contacts, including those for curative services. At the paediatric ward of the national hospital in Guinea-Bissau, there are more than 2600 yearly contacts with measles-un or under-vaccinated children aged 9-59 months, but no vaccines are given. In a randomised controlled trial, we will assess the effect of providing MV vs placebo to 5400 children at hospital contacts (at discharge or after an out-patient consultation) to test the hypothesis that MV reduces the risk of admission or death (composite outcome) by 25% over the subsequent 6 months.

Interventions

  • Biological measles vaccine
    Measles vaccine, Edmonston-Zagreb strain, 0.5 ml administered as a subcutaneous injection
  • Other Saline
    0.9% NaCl

Primary outcome measures

  • Non-accident mortality or admission (Composite outcome) [Time frame: 6 months]
Secondary outcome measures (3)
  • Non-accidental mortality [Time frame: 6 and 12 months]
  • Non-accidental hospital admission with an overnight stay in any health facility [Time frame: 6 months]
  • Cause specific hospital admissions at the national hospital. [Time frame: 6 months]

Eligibility criteria

Inclusion criteria

  • Measles-unvaccinated children

Measles-under-vaccinated children (received first but not second dose of MV)

  • 15-59 months with a hospital contact (discharged or outpatient consultation) at the paediatric ward at the national hospital Simao Mendes.

Exclusion criteria
