The Case for Vaccination at 80 and Beyond
As we age, our immune systems naturally weaken, a process called immunosenescence. This can allow the varicella-zoster virus, which causes chickenpox, to reactivate from its dormant state and cause shingles. The risk of developing shingles and experiencing severe complications is highest in older adults. The shingles vaccine is designed to bolster the immune system's defense against this reactivation.
Why Shingles Poses a Greater Threat to Older Adults
Shingles can lead to more serious and lasting complications in older adults. Information on specific complications can be found on {Link: NCOA website https://www.ncoa.org/article/how-long-does-the-shingles-vaccine-last/} and {Link: UCHELATH website https://www.uchealth.org/today/shingles-vaccines-prevent-painful-infections-and-cut-the-risk-of-dementia/}.
Shingrix: The Recommended Vaccine for Seniors
The CDC recommends Shingrix for healthy adults aged 50 and older. It is a non-live vaccine that is over 90% effective at preventing shingles in adults 70 and older. Shingrix is given as a two-dose series, with doses separated by 2 to 6 months. The older Zostavax vaccine is no longer available in the U.S..
Effectiveness and Safety at Advanced Ages
Shingrix shows high effectiveness in older adults, offering about 91% protection against shingles and 89% against PHN for those 70 and older. Protection remains high for at least seven years.
Side effects are usually mild and temporary, such as pain at the injection site, fatigue, and headache. These are generally less severe than a shingles infection.
What if the 80-Year-Old Has Other Health Conditions?
Seniors with existing health conditions can often receive the vaccine after consulting with a healthcare provider. Shingrix can be given to many individuals with compromised immune systems, sometimes with an adjusted schedule.
Shingles Vaccine vs. Chickenpox Immunity
Prior chickenpox infection offers some immunity that decreases over time. Vaccination is recommended even for those who had chickenpox.
Important Considerations Before Vaccination
Consulting a doctor is advised, especially if you have an active shingles infection, a history of severe allergic reaction to Shingrix, or are immunocompromised. Check Medicare Part D for coverage.
Shingrix vs. Zostavax: A Quick Comparison
| Feature | Shingrix (Recombinant Vaccine) | Zostavax (Live Attenuated Vaccine - Discontinued in the U.S.) |
|---|---|---|
| Effectiveness (Age 70+) | >90% | <20% |
| Doses Required | 2 doses (2-6 months apart) | 1 dose |
| Virus Type | Non-live (adjuvanted) | Live attenuated |
| Target Population | Adults 50+ and immunocompromised adults 19+ | Adults 60+ (older recommendations) |
| Long-Term Protection | >7 years | Wanes substantially after 5 years |
| Status in U.S. | Recommended and widely available | Discontinued as of November 2020 |
Conclusion: Vaccination is a Wise Choice
Getting the shingles vaccine is a valuable step for an 80-year-old to protect against a painful illness and its potential complications. Shingrix is highly effective and recommended, offering significant protection with manageable side effects. Discussing vaccination with a healthcare provider ensures a personalized approach.
