“he mumps outbreak also spread to Ocean County, New Jersey, where 159 confirmed cases have been diagnosed since September, county spokeswoman Leslie Terjesen told CNN. An additional 70 others are suspected of having mumps, she said.

Only seven of the infected are not Orthodox Jewish, but they all had exposure to the community, Terjesen said. The average age of the sick is 21, she said.

Lakewood, New Jersey, Rabbi Yehunda Pirutinsky was surprised when his 14-year-old son was diagnosed with mumps a week ago. Lakewood is in Ocean County.

“He was completely vaccinated,” Pirutinsky said. “So it was a surprise to us he came down with mumps.”

Anyone fully vaccinated from mumps receives two doses of the vaccine, according to the CDC. Of the New Jersey cases, 77 percent were vaccinated, Terjesen said.

But the vaccine is not 100 percent effective, according to the CDC. At two doses, the vaccine is 76 to 95 percent effective, the CDC says on its Web site.”

Impressive huh? The vaccine is 76-95% effective!

quote: The disease is predominantly affecting the 16 to 25-year-old age group and outbreaks have hit several colleges, as well as young working adults.

Impressive long-term immunity?

And now we have mumps outbreaks in NY and NJ. The timing turned out to be exceptionally good. http://www.wnyc.org/news/articles/143118
