Dolly Parton donates $1m to help with Moderna COVID-19 vaccine
Moderna is the second American drugmaker after Pfizer to report exciting vaccine results, raising hopes that the US could have two vaccines authorised for emergency use in December.
But unlike Pfizer’s vaccine - which must be shipped and stored at -70C - Moderna’s shot can be stored at normal fridge temperatures, which should make it easier to distribute.
“We are going to have a vaccine that can stop COVID-19,” Moderna President Stephen Hoge said in a telephone interview.
Moderna’s preliminary analysis was based on 95 infections among trial participants who received the vaccine or a placebo. Only five infections occurred in volunteers who received the vaccine, which is administered in two shots 28 days apart.
