This is absolutely not true. The varicella vaccine was developed in the last 20 years, with widespread vaccination occuring in the last 10 years. The vast majority of patients suffering from shingles are patients over the age of 55. Chickenpox is the acute infection caused by the initial exposure, and shingles occurs as the flareup of the latent virus, caused by the natural weakening of the aging immune system. The pediatric varicella vaccines have significantly decreased mortality rates--by something like 95%, decreased missing days of school, scarring, and secondary infections. The shingles vaccine prevents the debilitating and potentially permanent neuropathy--which requires lifelong treatment with medications to control symptoms. These vaccines have provided an immeasurable benefit to public health, and one which you will eventually gain an appreciation for.
