ShopRite is closing 23 pharmacies in New Jersey over the next month. The decision comes just weeks after the Garden State-based grocery chain said dozens of its stores would administer the COVID-19 vaccine.

A spokeswoman for ShopRite didn’t specify which locations would shutter but said affected customers will be notified and their prescription information will be transferred to the nearest CVS.

“The pharmacy industry is highly competitive and we were unable to sustain sufficient sales despite our marketing efforts, which led to the difficult decision to close these store pharmacies,” said Karen O'Shea, a spokeswoman for Wakefern Food Corp, that operates ShopRite-branded supermarkets.

It's not clear how many employees will be laid off, but pharmacists and technicians will have a chance to interview with CVS and support staff will be reassigned elsewhere in the stores, O’Shea said.

The planned closures won't affect the vaccination program that's currently operating in 39 locations. More than 30,000 people have received the vaccine at ShopRite's pharmacies, though no appointments are currently available due to limited supply.
