Synopsis As Introduced Creates the Access to Medically Necessary Vaccinations Act. Provides that any health care provider in this State must provide a vaccination to a patient if: the patient has requested the specific vaccination to be administered; the health care provider has determined that the vaccination is medically necessary; and the health care provider has a stock of one or more doses of the vaccination that have not been reserved for another patient. Prohibits a health care provider from preventing a medically necessary vaccination from being administered to a patient by keeping separate stocks of the vaccination for patients with private insurance and stocks of the vaccination for patients with Medicaid.
