Mississippi saw a steep decline in COVID-19 vaccinations last week as several drive-thru vaccination sites were closed because of freezing temperatures and icy roads. The state Department of Health said Monday that 32,540 vaccinations were given in the state during the week that ended Saturday. That is down from 106,691 the previous week, which was Mississippi’s busiest week for the vaccinations so far. The department said it is automatically rescheduling appointments that had to be canceled at 21 drive-thru sites, and people are being notified by text or email.
