Understanding the Risk of RSV in Older Adults
Respiratory Syncytial Virus (RSV) poses a significant risk to older adults with weakened immune systems. While it may cause mild symptoms in younger people, RSV can lead to severe lower respiratory tract illnesses like pneumonia or bronchiolitis in seniors, potentially resulting in hospitalization or death. The risk is particularly high for those with chronic heart or lung conditions.
Who Is Eligible for the RSV Vaccine?
The Centers for Disease Control and Prevention (CDC) provides recommendations for RSV vaccination based on age and health factors. The CDC advises a single dose of an FDA-licensed RSV vaccine for specific groups:
- Adults aged 75 and older: Vaccination is strongly recommended for this age group due to their higher risk of severe RSV disease.
- Adults aged 50–74 at increased risk: For this group, vaccination is decided in consultation with a healthcare provider based on individual risk factors. Conditions increasing the risk of severe RSV include chronic lung or heart disease, weakened immune systems, certain neurological conditions, severe obesity, and residing in a nursing home.
Timing Is Key: When to Get the Shot
The optimal time for eligible individuals to get the RSV vaccine is typically in late summer or early fall (August–October in most areas of the U.S.), ahead of the RSV season.
A single dose is currently recommended and is expected to provide protection for at least two RSV seasons. If you have received a dose in a previous season, another dose is not needed at this time, though CDC recommendations may be updated as more data becomes available.
The Available RSV Vaccines for Seniors
Several FDA-licensed RSV vaccines are available for adults.
RSV Vaccine Comparison for Adults
Vaccine (Manufacturer) | Vaccine Platform | Notable Details |
---|---|---|
Arexvy (GSK) | Recombinant Protein | Adjuvanted, available since 2023 |
Abrysvo (Pfizer) | Recombinant Protein | Bivalent, protects against RSV A and B |
mResvia (Moderna) | mRNA | Uses mRNA technology, licensed in 2024 |
The CDC does not recommend one vaccine over another, as all three have shown high effectiveness in preventing severe illness. Consult your healthcare provider to determine the appropriate vaccine for you.
Effectiveness and Safety Data
RSV vaccines have demonstrated high effectiveness in older adults. In the 2023–2024 season, Arexvy was approximately 83% effective against RSV-related hospitalizations in adults 60+, while Abrysvo was around 73%. Protection against severe disease has been shown to last for at least two seasons.
Common side effects are generally mild and temporary, including pain at the injection site, fatigue, headache, and muscle or joint pain. Rare neurologic events, such as Guillain-Barré Syndrome (GBS), were noted during clinical trials for some vaccines. However, the CDC and FDA assess that the benefits of vaccination in preventing severe RSV disease for recommended populations outweigh the potential, rare risk of GBS.
Co-administration with Other Vaccines
The RSV vaccine can be administered concurrently with other adult vaccines, such as those for flu and COVID-19. While this might increase the likelihood of common side effects like fever, it can also enhance convenience. Discuss co-administration with your healthcare provider based on your preferences.
Cost and Coverage
For most seniors, the RSV vaccine is covered. Medicare Part D covers all vaccines recommended by the ACIP, including the RSV vaccine, resulting in no typical out-of-pocket costs for individuals with Part D. Most private health insurance plans also provide coverage without cost-sharing. Assistance programs may be available for those without insurance.
Conclusion: Making an Informed Decision
Ultimately, the decision to get the RSV vaccine depends on your age and health profile. The CDC recommends it for all adults 75 and older and for those 50-74 with elevated risk of severe illness. The vaccines are highly effective against severe disease with manageable side effects. With the optimal vaccination period approaching, seniors should talk to their healthcare provider to determine eligibility and make an informed decision for their respiratory health this season.
