How many young people under the age of 18 have died while having the Corona Virus in the state of California in the USA with a population of 39.5 million?
CDPH shows 104 as of May 9, 2023. This is 0.0002% of the California population. Have a health problem or over 80, yes it is dangerous but so is the Flu and Pneumonia.
Sweden with 10 million people never had any mask mandate and had the same results as the state of California! - - References: CDPH , Flu and Sweden
