North Carolina public health officials say they're experiencing shipping delays that could cause providers to have to reschedule COVID-19 vaccine appointments. The Department of Health and Human Services says few Pfizer doses have shipped this week. Doses of the Moderna vaccine have yet to arrive. The inclement weather is causing delays across the country as states work to vaccinate people. North Carolina was expected to receive over 163,000 doses of the Moderna vaccine and nearly 127,000 does from Pfizer. People living in rural communities are more likely to get Moderna shots because of shipping and packaging constraints.
