Not to mention the cholera pandemics, polio and rampant tuberculosis. In
the mid 20th century every large town and city had its TB sanatorium,
polio hospital and isolation hospital. Clean water and good sanitation
ended the cholera problem , vaccination stopped polio and tuberculosis,
not to mention smallpox which is now offically extinct. The first
vaccine for that was developed by Edward Jenner in 1796
By the time the fifth cholera pandemic hit most major British and US
cities had cracked the clean water and sanitation issues so got off
pretty lightly but it killed over 280,000 in Russia and another 120,000
in Spain.
Going back to Covid-19 here in the UK we have around 80% of the adult
population now fully vaccinated so although there are still lots of
cases around the rate of serious illness is low and deaths are running
at around the 0.5 to 1 per 100,000 people in the US,UK and EU. About the
same as common or garden influenza. Its now more of an inconvenience
than a killer thanks to the efforts of the companies such as Pfizer,
Astra Zeneca etc who developed them in record breaking time.
