Understanding RSV and Its Impact on Older Adults
Respiratory syncytial virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms. However, for certain high-risk groups, including older adults, it can lead to serious complications such as pneumonia and bronchiolitis. Each year in the U.S., RSV is responsible for an estimated 110,000–180,000 hospitalizations and 6,000–10,000 deaths among adults aged 65 and older. The risk of severe illness increases with age, making vaccination a critical defense for individuals aged 80 and older.
CDC Recommendations for the RSV Vaccine
As of recent guidelines, the CDC recommends a single dose of an FDA-approved RSV vaccine for all adults aged 75 and older. This specific age recommendation simplifies the decision-making process for those in this age bracket, including 80-year-olds, who do not need to consult a healthcare provider for a risk assessment beforehand. The goal is to provide broad protection to a population proven to be highly vulnerable to the virus.
Who Else is Recommended for the Vaccine?
In addition to the 75+ age group, the CDC also recommends the RSV vaccine for adults aged 50–74 who are at an increased risk of severe RSV disease. For this group, a discussion with a healthcare provider is part of the decision-making process. Risk factors that increase the potential for severe RSV include:
- Chronic heart or lung diseases, such as COPD or heart failure
- Weakened immune systems
- Certain underlying medical conditions like diabetes or chronic kidney disease
- Residency in a nursing home or other long-term care facility
Available RSV Vaccines and Their Benefits
There are currently three FDA-approved RSV vaccines available for older adults, and eligible individuals can receive any of them. These are GSK's Arexvy, Pfizer's Abrysvo, and Moderna's mResvia. All have demonstrated high efficacy in preventing severe RSV outcomes, such as hospitalization, in clinical trials and real-world studies.
Efficacy and Duration of Protection
Clinical trial data and post-licensure studies have shown strong results for RSV vaccines in older adults:
- Real-world effectiveness studies have shown Arexvy and Abrysvo to be approximately 73–83% effective at preventing RSV-associated hospitalizations in adults aged 60 and older during the first season after vaccination.
- A single dose of the RSV vaccine provides protection against severe disease for at least two years. This is different from the annual flu shot, and there is no need for revaccination at this time if a dose has already been received.
Comparing the RSV Vaccines
To help understand the differences between the available options, here is a comparison table based on available information:
| Feature | GSK's Arexvy | Pfizer's Abrysvo | Moderna's mResvia |
|---|---|---|---|
| Mechanism | Protein-based | Protein-based | mRNA-based |
| Primary Age Approval | 60+ (risk-based decision) & 75+ (broad recommendation) | 60+ (risk-based decision) & 75+ (broad recommendation) | 60+ (risk-based decision) & 75+ (broad recommendation) |
| Real-World Efficacy (Hospitalization) | ~83% (for adults 60+) | ~73% (for adults 60+) | Comparable real-world data still being collected. |
| Key Indications | Prevention of LRTD in older adults. | Prevention of LRTD in older adults and infants (via maternal vaccination). | Prevention of LRTD in older adults. |
Preparing for and Receiving the RSV Vaccine
If you or a loved one is 80 or older and has not yet received an RSV vaccine, it is recommended to get it. While vaccination can happen at any time of year, the best time is typically in late summer and early fall, just before the RSV season begins.
Where to Get the Vaccine
The RSV vaccine is widely available at various locations, including:
- Healthcare provider offices
- Local pharmacies, such as Walgreens
- Community health clinics
It is always a good idea to check with the provider or pharmacy beforehand to ensure availability and to confirm coverage with Medicare Part D, which typically covers recommended vaccines.
Potential Side Effects and Considerations
As with any vaccine, mild side effects can occur. These are usually temporary and may include pain, redness, or swelling at the injection site, headache, fatigue, or muscle aches. In rare cases, a small number of older adults in clinical trials experienced serious neurological conditions, including Guillain-Barré syndrome (GBS). Ongoing monitoring by the CDC and FDA supports that the benefits of preventing severe RSV disease outweigh this potential risk, especially for those aged 75 and older.
Staying Protected: More Than Just the Vaccine
While the RSV vaccine offers a robust layer of protection, it is still important for older adults to follow other preventative measures, especially during the RSV season (typically fall and winter). These include:
- Washing hands frequently with soap and water
- Avoiding close contact with sick individuals
- Cleaning and disinfecting frequently touched surfaces

Conclusion: The RSV Vaccine is a Smart Choice for Seniors
For an 80-year-old, getting the RSV vaccine is a medically recommended step toward proactive health management. It offers a high degree of protection against severe illness and can significantly reduce the risk of hospitalization. By staying informed and consulting with healthcare professionals, older adults can take control of their health and minimize the risks associated with respiratory syncytial virus.
