To combat COVID-19, Moderna launched a Phase 1 study consisting of 45 participants in an effort to create a vaccine on an expedited timeline. March 16th was the start of the Phase 1 testing. The initial group of 45 people were divided into groups of 15 individuals. Each grouping received 2 doses of treatment, but each group received a different dosage of the proposed vaccine (25, 100, or 250 microgram dosages). The subjects who received both doses, showed higher levels of virus-defeating antibodies when compared to individuals who had recovered from the coronavirus. The majority of participants who received both dosages did report adverse reactions, as to be expected during the trials.
