Jay and I decided to get Shingrix injections. We got the first ones today. The vaccine requires two doses, so we will need to return for our second shots within a two to six month window.Of course, I'd heard about singles before. So it was rather interesting doing research to learn a little more about it.
What is Shingles?
Shingles is caused by the reactivation of the varicella-zoster virus, which is the same virus responsible for chickenpox. After recovering from chickenpox, the virus remains dormant in your nerve tissue. Years later, it can reactivate, often triggered by a weakened immune system due to aging, stress, illness, or certain medications.
The condition typically presents as a painful rash, often in a stripe-like pattern on one side of the body. While shingles itself isn't contagious, the virus can spread to someone who hasn't had chickenpox or the chickenpox vaccine, causing them to develop chickenpox instead.
Effects of Shingles on the Brain
Recent studies have found a link between shingles and an increased risk of cognitive decline. Shingles, caused by the reactivation of the varicella-zoster virus, may contribute to cognitive issues through mechanisms like neuroinflammation or direct neuronal injury.
One study revealed that individuals who have had shingles are about 20% more likely to experience subjective cognitive decline, which refers to self-perceived memory or cognitive issues that aren't detectable through formal testing. Interestingly, the shingles vaccine has been associated with a reduced risk of dementia, highlighting its potential benefits beyond preventing the painful rash.
Effects of Shingles on Cardiovascular Health
In addition, shingles has been linked to an increased risk of cardiovascular issues, including heart attack and stroke. Research suggests that the varicella-zoster virus, which causes shingles, may lead to inflammation in blood vessels and contribute to arterial damage. A study found that individuals who had shingles were about 30% more likely to experience a major cardiovascular event compared to those who hadn't.
These elevated risks can persist for years after the shingles episode, making prevention through vaccination even more important.
Our Conclusion
Jay and I are not covered by any insurance for this vaccine. However, we decided to pay for the protection Shingrix can offer. At our Canadian pharmacy in British Columbia, two doses cost around the equivalent of $US 270. That is a small price to pay after considering what we'd learned about the potential outcomes of not getting it.
