RICHMOND, Va. (AP) — Virginia is seeing delays in this week’s COVID-19 vaccine shipments because of severe winter weather, the state health department said Thursday.

The Commonwealth will likely see a delay in the delivery of approximately 106,800 doses due to distribution channels in the Midwest and elsewhere that were shut down, the department said in a news release.

The state had been expecting about 120,000 doses this week, according to a department spokesperson.

Multiple vaccination events scheduled in the coming days have already been postponed due to weather conditions in Virginia, parts of which were covered in sleet, ice and snow Thursday. The department said that if additional events are canceled due to weather or shipment delays, providers will contact individuals about updated appointments.

The health department warned additional delays could be possible for vaccine orders placed this week, also due to weather.

“Even if the roads are clear in Virginia, the fulfillment of orders and the movement of these vaccine and ancillary supplies may be delayed in other parts of the country,” the news release said.
