Pharmaceutical company Pfizer revealed a 95% effectiveness rate for their coronavirus vaccine and will be submitting it for FDA authorization within days. CNN's Sanjay Gupta reports.
The company's data is just days away from being submitted to the FDA, where a vaccine advisory committee will decide whether it deserves emergency use authorization. US biotech firm Moderna on Monday announced its experimental vaccine against #Covid-19 was almost 95 percent effective, marking a second major breakthrough in the quest to end the pandemic. Moderna's experimental COVID-19 vaccine is nearly 95% effective, the company announced Monday, citing preliminary results of its ongoing study, which showed that of 95 participants who contracted COVID-19, only 5 had received the vaccine. At least 45 states are reporting an uptick in cases and a week after competitor Pfizer announced its own experimental vaccine is 90% effective. Unlike Pfizer's vaccine, Moderna's does not have to be stored at ultra-low temperatures using special equipment. The results published by Oxford University show 90 percent effectiveness, including participants in age groups most at risk. AstraZeneca's vaccine is also significantly cheaper and is easier to store and transport.
