Stat News: AstraZeneca Covid-19 vaccine study is put on hold
The large, Phase 3 study testing the vaccine has been put on hold due to a suspected serious adverse reaction in a participant in the U.K.
This type of pause is reportedly standard when a serious side effect arises, but it shows why it’s highly unlikely a vaccine will be available by election day.
Astra halt is not doom for the program or for vaccines in general (esp. given how little we know) we're testing new shots on tens of thousands of people and there will be unusual reactions. This is why you run big trials and don't rush the process. https://t.co/TZIfAbLEy9
