Wild idea. Suppose most teenagers got infected with Corona. Statistics show about 2% of them will die. In a few months, most of them have recovered. Now you've got a section of the population that's immune to Corona, and won't again become carriers.
@tuh It seems they don't really know if you become immune or not. It could be as the flu, you can have flu several times in your life.
@Znaiz Yeah I wasn't sure about that. The body would be immune to the strain that infected it, and not necessarily to others.
