RSV Vaccine for Adults: A Complete Guide

Estimated reading time: 8 minutes

The arrival of FDA-approved RSV vaccines represents a significant breakthrough in protecting vulnerable adult populations from the potentially severe consequences of RSV infection. Annually, RSV infections contribute to a substantial number of hospitalizations and deaths among older adults in the U.S. The development and approval of these vaccines offer a crucial tool in mitigating this significant public health concern.

Currently, three RSV vaccines have received FDA approval for use in adults: Arexvy (GSK), mResvia (Moderna), and Abrysvo (Pfizer). These vaccines offer a new level of protection against a virus that has previously been largely overlooked in adult vaccination strategies.

The Centers for Disease Control and Prevention (CDC) provides clear recommendations regarding RSV vaccination for adults:

While the FDA has approved Abrysvo and mResvia for adults aged 18-49 years at increased risk for RSV-Lower Respiratory Tract Disease (LRTD), the Advisory Committee on Immunization Practices (ACIP) awaits further data before issuing broader recommendations for this younger age group. This highlights the ongoing evaluation and refinement of vaccination strategies as more real-world data emerges.

Clinical trials have demonstrated the effectiveness of these vaccines in preventing severe RSV-related illness:

A significant multi-state study further reinforced the efficacy of RSV vaccines, showing a 58% reduction in hospitalization risk across two seasons. However, it also highlighted that effectiveness can vary among high-risk groups, such as those with compromised immune systems. This underscores the importance of individual risk assessments when considering RSV vaccination.

The RSV vaccines have a generally favorable safety profile. The most common side effects are mild and transient, often limited to swelling or pain at the injection site.

A rare potential side effect is Guillain-Barré syndrome (GBS). While this has been observed in a small number of older adults, the FDA and ACIP maintain that the benefits of RSV vaccination far outweigh the extremely low risk of GBS. Continuous monitoring systems track GBS cases to ensure the safety and efficacy of the vaccines remain paramount.

Pfizer’s Abrysvo is also approved for pregnant individuals between 32 and 36 weeks of gestation. This provides passive immunity to infants, protecting them from RSV from birth through 6 months of age – a period of high vulnerability.

The three approved RSV vaccines are covered by Medicare Part D prescription drug plans, improving access for eligible seniors. However, cost and access remain important considerations, particularly for uninsured or underinsured individuals.

Research continues to address several key areas:

These ongoing research efforts are crucial to refining vaccination strategies and optimizing protection against RSV in diverse populations.

The adoption of RSV vaccines is a global effort. Countries like Canada have also implemented recommendations for older adults, tailoring guidelines based on specific age groups and risk factors. This collaborative international approach ensures a coordinated response to address the global burden of RSV disease.
