That doesn’t mean that a child who has had only a single dose of, say, the measles vaccine, is unprotected. “Some people may on one dose generate [a] long-lasting and very specific immune response. Some people may need two doses,” said Tosh. “It’s difficult to determine who those people are going to be.” Which is why, he stressed, “I would recommend if people have not gotten their full initial complement of vaccines, to get their catchup doses.”
