COVID-19: New vaccine shows 95% protection

A new vaccine for coronavirus is nearly 95% effective, data from manufacturer Moderna shows

A new vaccine for coronavirus is nearly 95% effective, data from manufacturer Moderna shows.

An interim analysis released on Monday, and based on 95 patients with confirmed Covid infections, found the candidate vaccine has an efficacy of 94.5%. In the analysis, 90 of the patients received the placebo with the remaining five the vaccine.

‘This is a pivotal moment in the development of our COVID-19 vaccine candidate. Since early January, we have chased this virus with the intent to protect as many people around the world as possible. All along, we have known that each day matters. This positive interim analysis from our Phase 3 study has given us the first clinical validation that our vaccine can prevent COVID-19 disease, including severe disease,” said Stéphane Bancel, Chief Executive Officer of Moderna.

The vaccine potentially has an advantage over the other recently announced vacciner from Pfizer, as it can be stored at much higher temperatures. Moderna's vaccine appears to be easier to store as it remains stable at minus 20C for up to six months and can be kept in a standard fridge for up to a month. Pfizer's vaccine needs ultra-cold storage at around minus 75C, but it can be kept in the fridge for five days.

‘We believe that our investments in mRNA delivery technology and manufacturing process development will allow us to store and ship our COVID-19 vaccine candidate at temperatures commonly found in readily available pharmaceutical freezers and refrigerators,” said Juan Andres, Chief Technical Operations and Quality Officer at Moderna.
