He thanked all Pennsylvanians who helped make the “big vaccine milestone” happen.

As COVID-19 cases continue to rise, fueled by the more contagious delta variant and the unvaccinated, Wolf has said the state’s strategy to stem the virus’ spread is to get more shots into arms rather than issue a mask mandate.
