If everyone on earth had to be vaccinated at least 3 times, that will be 8 billion people x 3 doses= 24 billion doses. Which means if every manufacturer made a vaccine every second, it would take 32 years to make 1 billion doses and if five companies had five plants making vaccines at 1 per second, it would take 10 years to produce 7.8 billion doses to vaccinate the population. So how was 7.8 billion doses manufactured in a period of 1 year and 11 billion doses manufactured between the period of 2020 and 2022 and administered for a novel virus that had only been around since 2019?
