This is the mortality rate in the 100 weeks before the vaccine was given:
The y-axis is the MR is the mortality rate in deaths per 100K person years.
The x-axis is the week since the shot was given.
The curves are an average for all doses, and all ages, over all time periods.
It’s tough. Take your time on this one.
P.S. If you answered “They look the same” you can get a job at the CDC or FDA in product safety in a heartbeat. They are looking for people like you!
