Thanks Reza. I have attached the data in a text file. About the second question, there is no first vaccine is 0. You always have either a first vaccine or missing values.

To count only DISTINCT patients in a given year : proc sql; create table counts as select year_of_vaccine, count (distinct patient_id) as count from have0 group by year_of_vaccine; quit; proc transpose data=counts out=want(drop=_name_); var count; id year_of_vaccine; run;

Realizing this doesn't match your output. You have your lines repeated, I only have the final line so this may not be what you need.
