this line should be indented as now ndoses gets reduced by 1 regardless of what happens in the if

else:
raise OutOfDosesException

I'm not sure what 'raise' does. How is it different from 'print'?

Using raise allows me to do stuff like

try:
   # something
except OutOfDosesException:
   # do something else


N = 100
ndoses = 120
threshold_age = 70
population = generate_random_population(N)
apply_vaccine_to_population(population, ndoses, threshold_age)
# Create a dictionary mapping vaccine name to respectice number of occurence.
# Ex: Counter(["pfizer", "pfizer", "moderna"]) -> {"pfizer": 2, "moderna": 1}
brand_histogram = collections.Counter([lookup_vaccine_name(ind) for ind in population])
