What is the cause of a rash after measles-mumps-rubella vaccination?

“We describe a 17-month-old child with fever and rash after measles-mumps-rubella vaccination. Detection of vaccine-strainmeasles virus in his urine by polymerase chain reaction confirmed the diagnosis of a vaccine reaction rather than wild-type measles. We propose that measles virus should be sought and identified as vaccine or wild-type virus when the relationship between vaccination and measles-like illness is uncertain.”

A prefecture-wide survey of mumps meningitis associated with measles, mumps and rubella vaccine.

“A survey of untoward reactions, especially central nervous system reactions, after the administration of a newly introduced measles, mumps and rubella (MMR) vaccine in Gunma Prefecture, Japan, was initiated soon after 4 patients were hospitalized for aseptic meningitis. Thirty-five, 6 and 2 children developed meningitis, convulsive disorders and parotitis, respectively, within 2 months after MMR vaccination during the 8-month period extending from April to November, 1989.”

Mumps epidemic in vaccinated children in West Switzerland

“Since 1991, 6 years after the recommendation of universal childhood vaccination against measles, mumps, and rubella (MMR triple vaccine), Switzerland is confronted with a large number of mumps cases affecting both vaccinated and unvaccinated children. Up to 80% of the children suffering from mumps between 1991 and 1995 had previously been vaccinated, the majority with the Rubini vaccine strain.”

Postpartum rubella immunization: association with development of prolonged arthritis, neurological sequelae, and chronic rubella viremia

“Six women developed chronic long-term arthropathy after postpartum immunization against rubella. All individuals developed acute polyarticular arthritis within 12 days to three weeks postimmunization and have had continuing chronic or recurrent arthralgia or arthritis for two to seven years after vaccination.”

A clinical analysis of gelatin allergy and determination of its causal relationship to the previous administration of gelatin-containing acellular pertussis vaccine combined with diphtheria and tetanus toxoids.

“Most anaphylactic reactions and some urticarial reactions to gelatin-containing measles, mumps, and rubella monovalent vaccines are associated with IgE-mediated gelatin allergy. DTaP immunization histories suggest that the gelatin-containing DT”
