We have a vaccine that prevents shingles. We have a vaccine that markedly lowers the risk of dementia. We have a vaccine that might even slow aging itself.
Conveniently, these three vaccines are actually just one: the shingles vaccine.
In 2006, the FDA approved the vaccine Zostavax for adults aged 60 and older. For people previously infected with varicella-zoster virus, which causes chickenpox, the infection actually doesn’t end. The sneaky virus lies dormant in nerve tissue and can subsequently spring to life to cause shingles. Zostavax, and its more effective replacement, Shingrix, train your immune system to fight varicella-zoster in case it emerges from hiding to attempt a bodily coup.
That’s a good thing because you really, really don’t want shingles. About 1 in 3 Americans will get it at some point. Its signature symptoms are a bubbly, blistering rash that traces the infected nerve, coupled with debilitating pain that’s been the subject of many painful-to-read Reddit posts. Sufferers use words and phrases such as “unrelenting,” “white hot,” and “I wish I could rip my arm out!”
So if you’ve had chickenpox in the past, it’s definitely worth your while to get vaccinated. The CDC actually recommends the shot for all adults aged 50 and older and all adults aged 19 and older who have weakened immune systems – because oftentimes you can be infected with varicella-zoster virus even if you’ve never developed chickenpox.
