Three Brooklyn toddlers who were not vaccinated have been diagnosed with measles.

All the children were 2 years old but the cases do not appear to be linked, the Health Department said Thursday.

The agency did not say how the youngsters contracted the virus but warned all parents to vaccinate their children.

“Measles is highly contagious,” the agency wrote in a letter to doctors, urging them to make sure children receive their first dose of the MMR vaccine by age one.

The city has experienced a surge in the number of measles cases this year, counting 16 between January and June compared to zero during the same time last year.

Half of the cases were among international travelers and weren’t linked, officials said.

Some medical experts think measles is making a comeback because some parents skip the vaccination out of unfounded fear it could cause autism.

A study linking the shots and autism turned out to be a fraud.
