Moderna Vaccine Shown to be More Effective than Pfizer’s


The COVID-19 vaccine being currently developed in the US by Moderna has shown to be 94.5% effective at protecting people from the virus, according to interim reports.

The vaccine, which is being produced in collaboration with the US Government’s ‘Operation Warp Speed’, has also been shown to last for up to 30 days in household fridges and at room temperature for up to 12 hours – which makes it also better to store than Pfizer’s vaccine.



In fact, it also remains stable at -20C, which is equal to most household or medical freezers, for up to six months.

Moderna’s CEO, Stephane Bancel, described this as a ‘pivotal moment’ in the company’s development of the COVID-19 vaccine. He said that since early January, Moderna has ‘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.”
