3rd major COVID-19 vaccine shown to be effective and cheaper

Drugmaker AstraZeneca said Monday that late-stage trials showed its COVID-19 vaccine is highly effective, buoying the prospects of a relatively cheap, easy-to-store product that may become the vaccine of choice for the developing world. The results are based on an interim analysis of trials in the U.K. and Brazil of a vaccine developed by Oxford University and manufactured by AstraZeneca. No hospitalizations or severe cases of COVID-19 were reported in those receiving the vaccine.
