Childhood vaccination against preventable infectious diseases has substantially reduced morbidity and mortality. Though Vaccine regimens are adopted only after rigorous safety and efficacy studies, vaccine-related adverse events, however rare are still of significant consequences.

We present a case of a toddler presenting with recurrent swelling at the site of MR (measles- rubella) vaccination which was diagnosed as foreign body giant cell granuloma, which has not been previously reported.

Keywords: Measles Rubella (MR) vaccine, delayed hypersensitivity (DTH), granuloma.
