AstraZeneca likely to do another study of Covid-19 vaccine after accidental lower dose shows higher efficacy

AstraZeneca and Oxford University on Wednesday acknowledged a manufacturing error that has raised questions about their Covid-19 vaccine after revealing earlier this week it was “highly effective” against the disease. AstraZeneca is likely to conduct an additional global trial to assess the efficacy of its Covid-19 vaccine, according to the company’s CEO.

The vaccine's rollout to the rest of the world likely won't be affected, according to AstraZeneca's CEO, since the studies that have been conducted, including safety data, are already in place from participants around the world outside of the U.S.

While vaccine candidates from Moderna and Pfizer have also shown robust efficacy in early Phase 3 data, hopes are riding high on the AstraZeneca version because it relies on a different technology, can be stored and transported at standard refrigerator temperatures rather than frozen, and costs just a fraction per dose compared to the other two leading vaccines in development.
