From the Guidelines
Gardasil can be considered as an adjunct therapy in the treatment of Recurrent Respiratory Papillomatosis (RRP), particularly for reducing the severity of the disease, as suggested by limited data. The use of Gardasil in this context is off-label, but it may help in boosting the immune response against HPV types 6 and 11, which are primarily responsible for RRP [ 1 ]. The standard quadrivalent Gardasil vaccine is administered as a series of three intramuscular injections over 6 months, and for RRP patients, it may help reduce the frequency of surgical interventions and slow disease progression by stimulating antibody production against HPV viral proteins [ 1 ]. However, it is crucial to note that results can vary among patients, and Gardasil should be used alongside standard surgical management rather than as a replacement.
Key Considerations
- The primary goal of using Gardasil as an adjunct therapy in RRP is to reduce the severity of the disease and potentially decrease the need for frequent surgical interventions.
- Patients should be informed that this approach is considered off-label and that outcomes can be variable.
- Continued follow-up with an otolaryngologist is essential to monitor disease progression and determine the need for additional interventions.
- The decision to use Gardasil as an adjunct therapy should be made on a case-by-case basis, considering the individual patient's disease course and response to standard treatments.
Treatment Approach
- Gardasil is administered in a series of three intramuscular injections over 6 months.
- It is used in conjunction with standard surgical management of RRP.
- The vaccine's role is to boost the immune response against HPV types 6 and 11, potentially helping to control existing infection and prevent spread to new sites [ 1 ].
From the Research
Gardasil as an Adjunct Therapy in RRP Treatment
- Gardasil, a human papillomavirus (HPV) vaccine, has been explored as a potential adjunct therapy in the treatment of Recurrent Respiratory Papillomatosis (RRP) 2, 3.
- RRP is a rare disease caused by HPV types 6 and 11, characterized by the proliferation of benign squamous cell papillomas within the respiratory-digestive tract, predominantly the larynx 3.
- The use of Gardasil as an adjunct therapy in RRP treatment is based on its ability to induce neutralizing antibodies against capsid antigens of HPV types 6 and 11, which are associated with RRP 3.
Efficacy of Gardasil in RRP Treatment
- Studies have shown that Gardasil vaccination can reduce the frequency of surgical interventions and lessen disease severity in RRP patients 4, 5, 6.
- A retrospective study found that only 15.4% of vaccinated patients developed a recurrence of the disease, compared to 100% of unvaccinated patients 4.
- A systematic review and meta-analysis found that the number of surgical procedures per month was significantly reduced after HPV vaccination compared to before vaccination 5.
- Another study found that the cumulated Derkay score per year decreased after second and third vaccination, indicating a reduction in disease burden 6.
Factors Influencing the Decision to Vaccinate
- The decision to vaccinate RRP patients with Gardasil is influenced by multiple factors, including potential side-effects, sociocultural factors, impact of social media, pre-existing conditions, and the wider context of the recent pandemic 6.
- It is crucial to overcome skepticism towards vaccinations to prevent the development of HPV-associated diseases in the first place 6.

Additional Considerations
- The use of Gardasil as an adjunct therapy in RRP treatment is still being researched, and more studies are needed to fully understand its efficacy and safety 2, 3, 4, 5, 6.
- However, the available evidence suggests that Gardasil may be a useful adjunct therapy in the treatment of RRP, particularly in reducing the frequency of surgical interventions and lessening disease severity 4, 5, 6.
