Fairfield County Child Contracts Measles: DPH - NBC Connecticut

One dose of the measles vaccine is approximately 93% effective at preventing the virus if exposed and two doses are about 97% effective.

Three to five days after the start of these symptoms, a red or reddish-brown rash appears, usually starting on a person’s face at their hairline and spreading downward to the entire body.

People with measles may be contagious up to four days before the rash appears and for four days after the rash appears.

The CDC recommends all children get two doses of the MMR vaccine, starting with the first dose at 12- through 15-months of age, and the second dose at four through six years of age
