What's going on with the AstraZeneca/Oxford vaccine? - a podcast by ABC News

As the days have passed since the drug company AstraZeneca announced its coronavirus vaccine results, the questions about those results and what they could mean have only grown.

Last week, AstraZeneca reported a 90 percent efficacy rate for its vaccine - but also another lower rate for another part of the trial.

Now questions are emerging around how the trial was run, and if parts of it were accidental or if they were on purpose.

It's all very confusing, so here's today's Coronacast to help sort it out.

Also on today's show:

* Why haven't Pfizer and Moderna been subject to similar criticism as AstraZeneca?

* Is there any logic to forcing international arrivals who may or may not be infected with coronavirus to quarantine in a hotel, yet those who are confirmed to be infected are able to stay at home?

And will Norman back down on his highly inflammatory pineapple pizza comments?
