Zhejiang is an eastern coastal province of the Peoples Republic of China and home to 55 million inhabitants. All children there receive a compulsory first dose of MR at 8 months and another dose of the MMR vaccine at 18–24 months. In the new study, researchers analyzed a subset of 1,015 Zehjiang inhabitants and found that despite the recent measles outbreaks 93.6% of them were seropositive for measles antibodies, meaning they had presumably vaccine-induced protective antibodies against measles in their blood serum -- more than is required to obtain so-called herd immunity threshold of 88%–92%, which is often claimed to be the solution to extinguishing infectious diseases altogether.[2] And yet despite this theoretical protection, eight-seven (8.6%) of the subjects developed measles anyway.
