Low effort content.
There were 5 Covid infections in the vaccinated group and 90 in the placebo group. The efficacy of 94% is simply 1-5/90.
When you have only 5 infections in the vaccinated group, you can have at most 5 minorities represented there. So, if for example you don't have any Native Americans, it will look like the efficacy for Native Americans is 100%.
The better title for MIT's research would be "No statistical difference for the vaccine efficacy across racial groups", but that wouldn't be so exciting, would it?
