The Pennsylvania Department of Health announced on Thursday that it did not receive a shipment of the Moderna vaccine on Monday, Tuesday, or Wednesday.

The situation is not much better with Pfizer. Pennsylvania did not receive any vaccines on Monday and then very limited supplies on Tuesday and Wednesday.

“We do understand that these weather delays will impact the ability to get vaccines into arms and we want to remind everyone who has a vaccine appointment scheduled to contact the provider before traveling,” said Lindsey Mauldin from the Pennsylvania Department of Health.
