Butler County reported seven more deaths Tuesday as state officials discussed vaccine disbursements.

A total of 132 county residents have died from COVID-19. In total, the state has lost 12,890 residents to the virus.

U.S. Sen. Bob Casey, D-Pa., spoke on the Senate floor Tuesday. He gave the names and legacies of five Pennsylvanians from various counties across the state who died because of COVID-19. Casey even cited portions of their obituaries and offered condolences to their families as they grieve.

“All of these families will miss their loved ones, not only when they're shutting out the lights or when they rise every morning, but every day and in many cases every hour of every day,” Casey said.

Casey said every Pennsylvanian has an obligation to prevent others from meeting the same fate. He said following the COVID-19 mitigation efforts is part of that obligation.

Wearing a mask, social distancing and proper hygiene have been widely publicized mitigation efforts. Casey asked for his fellow residents to continue these efforts until a vaccine is widely available to anyone who wants it.

“To honor those we have lost, we must all do our part,” he said.

In his own news conference Tuesday, Gov. Tom Wolf gave an update on vaccine distributions, which he said could be affected by inclement weather expected Wednesday.

“We're not making changes according to the forecast, but we will make changes if the weather forces us to make those changes,” Wolf said.

This week represented the first week of distribution of the Pfizer COVID-19 vaccine.

“These first doses of vaccine are being given specifically to health care workers through hospitals,” said Dr. Rachel Levine in a news release Tuesday. “Hospitals are making arrangements to implement these vaccinations, not only to their own front-line staff, but to other high-priority recipients.”

Philadelphia was one of six cities in the United States to receive direct shipments of the vaccine from the federal government. The rest of vaccine distribution to hospitals is being directed through each state's Department of Health.

Hospitals in Allegheny, Bucks, Crawford, Lebanon, Luzerne, Mifflin and Union counties received distributions Tuesday.

The Moderna vaccine, which uses the same technology as the Pfizer-BioNTech, could receive its own authorizations by the end of this week.

State officials have said once the Moderna vaccine becomes available, they could further expand into the second phase of their distribution plan, which involves vaccinating residents in nursing homes and other at-risk populations.

“The number of people we can immunize truly depends on how quickly the manufacturers can make the vaccine,” Levine said.

With the addition of 47 confirmed cases Tuesday, the county now has had 4,699 residents test positive for COVID-19, according to state data.
