UPDATE: S163 failed to move in the 2017 legislative session ended.  However, bills can carry over to 2018 in New York if the sponsor requests it.   

S163 was introduced on 1/4/2017 and referred to the Senate Health Committee.  This bill is sponsored by Senator Gustavo Rivera.  This bill would expand medical exemptions to vaccination by allowing nurse practitioners and physician assistants to write medical exemptions in addition to physicians.  This bill would also strengthen existing law concerning medical exemptions adding that the physician's, nurse practitioner's or physician's assistant's determination shall prevail.
