You know, chickenpox is a fairly mild infection. It's not that bad, but super-contagious. Like nobody dies from the thing. All it will usually do to a kid is cause them to have those little pustules all over their body, and if they burst while itching them, because they are horribly itchy, is leave a scar on the skin.
Fast forward some decades later, and they are at high risk to develop shingles. Shingles is 1,000 times worse than chickenpox. It is a devastating disease which can ruin a person's life until the end of their days.
These days, there is a chickenpox vaccine readily available for kids. And once they get that shot, they will no longer be susceptible to getting shingles when they get old.
So...Let's look at this logically.
Get a mild infection of the CPox and risk getting a life-destroying disease later in life, or JUST GET THE DARN CPOX SHOT and have no risk of getting the way-more destructive shingles infection?
Hrmm. The choice seems clear.
It could be the same thing with COVID. I guess it will take a few decades to know the difference between the kids who got the shot before being infected versus those who did not, to figure out if COVID will lead to something similar much later in life. Will COVID lead to the susceptibility of getting something more sinister in the coronavirus family of virii?
