Coronavirus Watch: Storm delays vaccinations in Florida, Texas

Winter storms across the nation Tuesday were slowing traffic and delaying vaccine shipments.

Officials said Florida has been alerted that shipments were being delayed. In Texas, state health officials, due to receive more than 400,000 additional vaccine doses this week, don't expect deliveries until at least Wednesday. And vaccine appointments in Houston and Austin were expected to be canceled.

Meanwhile, San Francisco became the latest California city to temporarily close a mass vaccination site this week because of a lack of vaccine, joining Los Angeles in pausing inoculations amid a national shortage.
