Global vaccine production in 2019 was about 4 billion doses; Covid-19 is forecast to be 12 billion doses, with as many as 15 billion needed. Using some volume estimates for the vaccines, it appears that final process liquid production of the vaccines is between 9 and 35 million liters per year. (Check out past global fluid estimates.)
A typical US household consumes 300 gallons per day (Source: USGS) – which would be 400,000 litres per year.
Strictly on a volume standpoint, global vaccine production is about equivalent to a small neighborhood (20 – 80 homes).
