After a year spent inside, the Fourth of July returned

Fourth of July celebrations made a triumphant return Sunday to the city where America began — to thunderous applause from concertgoers liberated after a year spent isolated in their homes by the pandemic.

Hundreds of families turned out for the annual Welcome America festival, some to see performances by recording artists Flo Rida and Bebe Rexha, others to reserve prime seats to watch the fireworks display on the Benjamin Franklin Parkway, and all eager to spend time outside.

Reporter Vinny Vella recaps a day of fireworks, food, and fun.

1 million Pennsylvanians have missed their second shot. They’ll need it against the Delta variant.

Due to more than 1,000,000 Pennsylvanians missing their second dose of the COVID-19 vaccination, the state missed its mark of 70% of residents inoculated by the end of last month.

In addition, the state’s no-show rate ranks among the highest in the nation, as medical professionals, officials, and researchers brace for a surge of variant cases this fall.

The Delta variant’s highly contagious nature has prompted new restrictions in places across the world, some of which are in contrast with the CDC’s guidance.

Reporters Justine McDaniel, Erin McCarthy, and Chris A. Williams detail the importance of the second dose in the continuing fight against COVID-19 and its variants.
