**Covid Vaccination - The Numbers**

I like to estimate systems by doing "back of the envelope" calculations.

My latest is on vaccinations.

The US population over 18 years of age is approx 248 million and lets assume 75% get vaccinated (each needs 2 doses) so that's a total of 372 million doses. Now let's suppose the US does this with one giant drive-through with 5,000 lanes!!! It takes 5 mins for one inoculation (including paperwork) and it runs 24/7.

Then it would take about 8 months to complete vaccinations!!!!!
