Shingles is painful, energy-draining and can strike without warning if you’ve ever had the chickenpox. After you’ve had chickenpox, the varicella-zoster virus (the virus that causes chicken pox) takes a little nap in the nerve tissue near your spinal cord and brain. If it “wakes up,” it reactivates as shingles, a painful rash with blisters. You may already know that the only way to prevent shingles is with the shingles vaccine. But did you know there’s a new vaccine on the market that, according to research, offers stronger, longer-lasting protection than the previous one?
