Mayo Clinic prepares for COVID-19 storage

The Pfizer vaccine must be stored at 94 degrees below zero

LA CROSSE, Wis. (WKBT) – Staff at Mayo Clinic are prepare to store the COVID-19 vaccine for when it becomes available.

The Pfizer vaccine must be stored at 94 degrees below zero.

By comparison, that’s 51 degrees colder than La Crosse’s low temperature record.

In order to keep the vaccine cold enough, Mayo Clinic will store it in multiple ultralow temperature freezers.

Thanks to those cold temperatures, it does take about three hours to thaw so it can be used.

That means getting a vaccine, at least initially, will need to be a planned in advance.

“It’s likely that, you know, there will be appointments for individuals to come in and we know when people come in for their vaccine. And we will have the doses of vaccine ready, ready for them,” said Mayo Clinic Health System regional pharmacy director Jenny Tempelis.

Moderna has said that its vaccine needs to be stored at minus 4 degrees.
