If you had the chickenpox as a child, you’re at risk for getting shingles as an adult. Nearly 1 in 3 adults in the United States will develop shingles in their lifetime. Shingles is a reactivation of the chickenpox virus that presents as a painful, itchy rash and shooting pain. It can happen without warning and often affects only one side of the body.
Since it is such an unpredictable condition, people often get vaccinated to decrease their chances of getting shingles. There are a few vaccines on the market, the first of which was Zostavax. Zostavax is designed to prevent shingles, but many people who got the vaccine still wound up with the condition or suffered more severe complications. Now, Zostavax manufacturer Merck is facing dozens of lawsuits accusing the company of making a defective product.
