Democratic Rep. Joe Morelle announced support on Friday for a pair of bills designed to boost the vaccination rates for children across the country.

The legislation comes as anti-vaccination advocates in New York have challenged a law that ends the religious exemption for kids to be vaccinated before attending school.

“One of the greatest threats facing our families is the rapid and dangerous spread of misinformation around the safety of vaccines. The science is clear: vaccines are safe, and they are effective,” Morelle said.

“It is our responsibility as adults to foster a healthy environment for children to learn, play, and grow. That is why I am proud to co-sponsor these pieces of legislation to encourage every family to get vaccinated and prevent the spread of serious and entirely preventable diseases.”

One bill is meant to increase the public awareness of the health benefit of vaccinations. Another bill is aimed at ensuring kids attending public schools who are medically able receive needed immunizations.

The legal challenge to the New York law ending the vaccination exemption so far has faced a series of setbacks in the state-level courts. Opponents have pledged to appeal the case to the state Court of Appeals, New York’s highest court.

Public health officials say health people should be vaccinated in order to prevent the spread of disease. Measles outbreaks in Brooklyn and Rockland County led to more than 1,000 reported cases earlier this year.

“As a Mom and as a Pediatrician, I have chosen to vaccinate myself and my children because I know it is the safest way to prevent these devastating diseases,” said Dr. Elizabeth Murray, Pediatrician at Golisano Children’s Hospital. “Ensuring that all who can be vaccinated are vaccinated is critical for a healthy community.”
