Who Should Not Receive the RSV Vaccine
The RSV vaccine is contraindicated for persons with a history of severe allergic reaction, such as anaphylaxis, to any component of the vaccine or to a previous dose of any RSV vaccine. 1, 2
Absolute Contraindications
Previous significant hypersensitivity reaction to RSV vaccine components
- Individuals who have experienced anaphylaxis or anaphylactic shock to a previous dose of any RSV vaccine
- Those with severe allergic reactions to any component of the vaccine
Moderate or severe acute illness
- RSV vaccination should be delayed for persons experiencing moderate or severe acute illness with or without fever (precaution) 1
Age-Related Considerations
- Adults younger than 60 years without specific risk factors are not currently recommended to receive RSV vaccination 1
- Adults aged 60-74 years without risk factors for severe RSV disease should not receive the vaccine, as ACIP concluded that the benefits of RSV vaccination did not clearly outweigh the potential harms in this population 1
Special Populations with Precautions
Pregnant Women
- For maternal RSV vaccination (RSVpreF/Abrysvo), vaccination is only recommended between 32-36 weeks' gestation to protect infants 1
- Pregnant women outside this gestational window should not receive the vaccine
Immunocompromised Individuals
- While immunocompromised adults ≥60 years are eligible for vaccination, there may be reduced vaccine effectiveness
- Healthcare providers should consider the potential for inadequate immune response when determining vaccination strategy 1
Patients with Bleeding Disorders
- As with any intramuscular injection, RSV vaccines should be given with caution to individuals with thrombocytopenia or any coagulation disorder 2
- This is a precaution rather than a contraindication, requiring clinical judgment
Risk-Benefit Assessment
For adults aged 60-74 years, vaccination is only recommended for those with specific risk factors for severe RSV disease, including:
- Chronic cardiovascular disease (excluding isolated hypertension)
- Chronic lung or respiratory disease
- End-stage renal disease
- Complicated diabetes mellitus
- Neurologic conditions affecting airway clearance
- Chronic liver disease
- Chronic hematologic conditions
- Severe obesity (BMI ≥40 kg/m²)
- Moderate or severe immune compromise
- Residence in a nursing home
- Frailty or other conditions determined by healthcare providers to increase risk 1
Revaccination Considerations
- Adults who have already received RSV vaccination should not receive another dose, as a single dose provides protection for at least two RSV seasons 1, 3
- The need for additional doses will be evaluated by ACIP in the future
Monitoring and Reporting
Adverse events after vaccination should be reported to the Vaccine Adverse Event Reporting System (VAERS), particularly for:
- Severe allergic reactions
- Guillain-Barré Syndrome (GBS), which has been identified as a potential risk with protein subunit RSV vaccines 1
- Any clinically significant adverse event, even if uncertain whether the vaccine caused it
By carefully screening patients for contraindications and precautions before administering RSV vaccines, healthcare providers can maximize the benefits while minimizing potential risks of vaccination.
