The measles virus was eliminated in the U.S.in 2000.
David R. Curry, executive director of the Center for Vaccine Ethics and Policy, told China Daily: "Once your child is exposed and has measles, there is no better convincing argument to parents who may be questioning whether vaccinations work than when they have to come to grips with the fact that their child, because they were unvaccinated, suddenly has a potentially risky disease". The bogus information has been debunked several times.
City health officials declined to comment on the mayor's order.
Opponents of the order are trying to block it in court, according to New York City civil attorney Michael Sussman, whose office confirmed that he is involved in legal matters related to the issue.
He also represents parents in Rockland County, a New York City suburb with a large Orthodox Jewish community, who challenged a local government executive order barring unvaccinated children from indoor public spaces.
The federal agency says that disease transmission for the recent cases likely originated in countries where measles is more common - throughout Europe, Asia, the Pacific and Africa and the Philippines - places people commonly visit.
Last week saw a minor victory for vaccination advocates amid the United States' ongoing measles outbreak: A Kentucky judge ruled against a lawsuit filed by 18-year-old Jerome Kunkel against the Northern Kentucky Health Department, claiming the department had discriminated against Kunkel by asking schools to exclude students not vaccinated for chicken pox from school and extracurricular activities. The change is contained in an amendment to a bill they had previously introduced to tighten the state's vaccination policy; lawmakers approved the revised plan in January, despite passionate testimony from people concerned about the push to reduce parental choice. "I'm not even sure that people know about it", Robert Krakow, a New York personal injury lawyer and prominent anti-vaccine advocate, told The New York Post about the city's emergency order. Latimer says none of the children attend public schools or childcare programs. Officials said the children all appear to have been exposed to measles in Rockland County or Brooklyn. "The vaccine has been proven safe and effective in preventing the spread of measles for decades and we have evidence".
