Distribution of vaccination delays

[choisy]

In order to have deeper insights into the distributions of delays, would it be possible to try:

• removing the long right tail that is likely to be errors again;
• also considering actual number of shots instead of frequencies only so that we can make comparisons between months.

As for the month to consider, I find the the month of expected vaccine shot much more meaningful that either the month of birth or the month of actual shot.
