I'm not sure what to make of this. A resolution was introduced in the Pennsylvania State Senate on February 25th, Senate Resolution 27. The primary sponsor is Sen, Kitchen, with Farnese, Vance, Yudichak, Greenleaf, Brewster, Haywood, and Rafferty as co-sponsors.
This is the gist of the resolution:
Directing the Advisory Committee on Public Health Law of the Joint State Government Commission to study the issue of youth vaccinations and immunizations to determine whether any amendments should be made to the Commonwealth's public health law.
The full text of the resolution does not really provide any context or background. So I cannot tell if it is a cover for people who don't like vaccinations or a ploy to add more required or recommended vaccinations.
