This would be good, but is also not as simple as it sounds to do well. Most of the published vaccine data doesn't state whether the person vaccinated was previously infected with COVID. Additionally, the CDC recommends getting vaccinated even if you were previously infected.

this is true. It is overly simplistic by design and meant to only answer the question "at today's daily average vaccination rate, how long until x-percentage of the population is vaccinated?".

Thanks! This is a good point - the current calculation is a quick and dirty approach to clearly answer the question "at today's rate, how long would it take us to get X-percentage of the population fully vaccinated?". But it may be better to count one dose differently. Or show the current % of population with one dose if that data is available (which it is for some countries)
