I was never vaccinated against chicken pox. Back then we just got it and we all lived. So why vaccinate against it ?
Because not everyone reacts the same and because you can cause damage to others. A lot people - as children - would have some uncomfortable but non-life threatening symptoms, and that would be that. Some people have it worse and get left with permanent scarring.
The worst though, is the effect on others. Chickenpox is highly contagious. If you got it as an adult, the symptoms and scarring are likely to be far more severe and you run an increased risk of developing varicella pneumonia. If you are a strong, healthy adult then you will probably live through it... but if you are not young, or are a smoker, or are immunocomprimised then your survival rate drops dramtically.
And if you were pregnant?
Unless you were vaccinated and therefore immune your child runs the risk of encephalitis and other brain damage, damage to the eyes, damage to the spinal cord or a raft of other complications. Oh - and that pneumonia, too.
We get vaccinated and practise herd immunity so that those who are at risk from diseases don't have to face that risk.
