Why do all babies get chicken pox? is it bad or good and why?

Not true: Not all babies get chicken pox, especially lately. Due to the advent of the varicella vaccine, fewer kids ever get active chickenpox.

Nothing good: Since the advent of the chicken pox vaccine, most babies no longer get chicken pox. Aside from the severe itching that occurs, the lesions can become infected and toxic shock syndrome can occur. Other conditions that can develop are chicken pox pneumonia, or encephalitis. So, if you havent vaccinated your child do it asap.
