Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 6 months to 6 years with confirmed sickle cell disease who are due for measles vaccination within three months and can attend follow-up visits and provide informed consent through a guardian.

Probably not a fit

Children with known primary immunodeficiency, cancer, or AIDS who cannot receive live measles vaccine, or children outside the 6-month to 6-year window, are unlikely to benefit from this study.

What this trial studies

This observational study will enroll children aged 6 months to 6 years with confirmed sickle cell disease who are due for a measles vaccine. Two cohorts will be followed: one receiving the first measles vaccine (MV1) and one receiving the second (MV2). Blood samples will be collected before vaccination and at 4 and 8 weeks after vaccination to measure antibody responses. Sites include Cincinnati Children’s Hospital Medical Center and collaborating hospitals in Ghana and Tanzania.

Why it matters

Potential benefit: If successful, the results could show whether standard measles vaccination produces adequate short-term protection in children with sickle cell disease and help guide immunization timing or booster recommendations.

How similar studies have gone: Measuring antibody responses after vaccination is a standard method and has been used in other populations, but data specifically on measles immunogenicity in sickle cell disease are limited.
