Quixplained: Why the Oxford Covid-19 Vaccine Error Matters and the Way Forward

The Oxford vaccine for Covid-19 is AZD1222.

What they did not initially reveal was that these findings were the result of an error.

The revelation added to doubts about how vaccine clinical trials have been handled during the pandemic. Here’s why it’s important and what to do now:
