Oxford and AstraZeneca’s COVID-19 vaccine candidate shows 90% efficacy in clinical trials.
The late-stage human trials for the COVID-19 vaccine candidate developed by Oxford University and AstraZeneca showed that the vaccine could be up to 90% effective.
The preliminary result showed that a lower dose appeared to be more effective. The volunteers were first given half a dose of the vaccine, followed by a full dose at least one month apart, efficacy was 90%. Whereas, when volunteers were given two full doses at least one month apart, efficacy was at 62%.
The combined analysis from both dosing regimens involving more than 11,000 volunteers resulted in an average efficacy of 70%.
Both companies said that more data will continue to accumulate and additional analysis will be conducted to improve the efficiency reading and establish the duration of immunization.

European Union snags 160 million doses of Moderna’s mRNA-based COVID-19 vaccine.
Moderna and the European Union recently finalized a deal to supply 160 million doses of the mRNA-based COVID-19 shot developed by Moderna. This is estimated to immunize 80 million patients based on Moderna’s two-dose regimen.
The newest supply agreement comes a week after the European Union accepted Moderna’s mRNA-1273 vaccine, for rolling review based on interim results from a phase 3 study showing 95% efficacy.
Moderna also plans to submit the vaccine for the US Food and Drug Administration’s (FDA) emergency use authorization within a few weeks.
