Who is at Highest Risk for Complications from Measles Vaccine?

Complications from measles vaccine

Measles vaccine complications appear to be more prevalent in children under age 5 and in adults over age 20 and in persons with immune deficiency disorders or those suffering from malnutrition or vitamin A deficiency.1 Also, according to the CDC, persons, who have a history of thrombocytopenia purpura (low platelet count), may be at increased risk for developing clinically significant thrombocytopenia after vaccination.2

The CDC and Merck publish measles vaccine contraindications, which list reasons why a person may be at increased risk for suffering a reaction to MMR vaccine.
