Rockland County held a free MMR vaccine clinic in Haverstraw to prevent the spread of measles.

Friday's event marked the second free clinic since a state of emergency was declared last month by County Executive Ed Day.

This week, a committee of six leading Hasidic rabbis urged the public to get protected from the disease despite their religious believes.

"Because this is a potential danger to life, everyone is obligated to care for his household and they should get the injection," said Yossi Gestetner of the Orthodox Jewish Public Affairs Council.

According to Rockland County Commissioner of Health Patricia Schnabel Ruppert, measles is the most infective virus on earth. She says 90 percent of people who are not immune to the disease will develop it if they are exposed.

Over 17,000 MMR vaccinations have been given in the county since the measles outbreak began last October.

Those who still haven't been vaccinated can contact their local health care providers or county health department where the vaccines are available.
