TL;DR: Essential workers have continued to do their jobs even in the face of the coronavirus’ rising death toll. But many of them feel unsafe and underappreciated. And as researchers seek to develop coronavirus vaccines, they face a host of unanswered questions about immunity.

🛑 Officials from two central Pennsylvania counties notified Gov. Tom Wolf that they will defy his guidance and move into the “yellow phase” of reopening starting May 15.

🏖️ Beaches in Ocean City, Sea Isle City, and Upper Township were opened this weekend for exercise and activities like surfing and fishing.

Local coronavirus cases

📈The coronavirus has swept across the Philadelphia region and cases continue to mount. The Inquirer and Spotlight PA are compiling geographic data on tests conducted, cases confirmed, and deaths caused by the virus. Track the spread here.

As the death toll from the pandemic has grown in Philadelphia, workers have continued bagging our groceries, answering our calls, driving our buses, caring for our vulnerable, guarding our prisons, cleaning our floors, delivering our packages, and securing our buildings. Many of these workers are women and people of color earning low and working-class wages.

My colleauges Jessica Calefati, Juliana Feliciano Reyes, and Barbara Laker spoke to more than a dozen people in essential roles. Many said they don’t feel protected or appreciated.

No one can say for sure yet how quickly people might be immune from the coronavirus if they’ve had it and recovered. The question isn’t just important on its own: How the immune system responds to the coronavirus will provide clues for how it might react to a vaccine.

My colleague Tom Avril explains how the complicated questions regarding immunity will have profound impacts on our future.
