Ridgewood NJ, previously reported on the Ridgewood blog that AstraZeneca issued a press release regarding preliminary results from the Phase 3 clinical trials of its candidate SARS-CoV-2 vaccine, developed in collaboration with Oxford University (UK). According to Johns Hopkins Center for Health Security ,the press release indicates that the vaccine demonstrated 90% efficacy when administered as an initial half-dose followed by a full dose a month later.
