Albany, N.Y. - State lawmakers are looking into closing what they call a loophole in New York's vaccination laws.
The push comes as the number of measles cases continue to grow statewide and across the country.
Currently the law requires children be vaccinated to attend public school. Parents can opt out for medical or religious reasons. But, some say the religious exemption is being abused and is causing more people to get sick during what's already a health crisis.
A new bill would require all kids be immunized unless they have a medical exemption. Governor Cuomo has raised questions about the legislation, saying there may be first amendment issues involved.
