This is an amazing result, vaccines are rarely this effective. The vaccine should be available to health care workers at the beginning of 2021, or maybe even in December given the lack of serious side effects. This is the one that needs to be stored at -70C (-94F). The two doses are given three weeks apart.
Moderna likely will report similar results in the next three weeks.
Moderna reports COVID-19 vaccine 94.5% effective. “This first interim analysis was based on 95 cases, of which 90 cases of COVID-19 were observed in the placebo group versus 5 cases observed in the mRNA-1273 group, resulting in a point estimate of vaccine efficacy of 94.5% (p <0.0001).”
Moderna announces longer shelf life for its COVID-19 vaccine candidate at refrigerated temperature. “Vaccine candidate now expected to remain stable at standard refrigerator temperatures of 2° to 8°C (36° to 46°F) for 30 days, up from previous estimate of 7 days. Shipping and long-term storage conditions at standard freezer temperatures of -20°C (-4°F) for 6 months.”
