Analysis:

There are 29 data points (rows) for the years 1991 to 2019.

Total n values:

Count_Disabled :
n=17,644

Count_Reactions:
n=759,483

The mean and median are very close to each other, indicating the data is not significantly skewed.

Both the mean and median are multiples (about 3.6 times) larger than the standard deviation, indicating that there is little variability.

Post vaccinations, the DISABLEd per year is pretty consistent. About 2.2% of all reactions year after year.

The trend is clear. Both the number of reactions, and the number of people becoming disabled after a vaccination are rising.
