Vaccines against human papillomaviruses are now commercially available. One of the commercial vaccine contains antigens of both LR HPV types which cause virtually all cases of RRP. Clinical trials have documented the safety and immunogenicity of this vaccine as well as its effectiveness in prevention of incident and persistent infection of the vaccinal types as well as a development of lesions caused by these types. After vaccination the antibodies level increases dramatically and the high levels of antibodies are present in the blood still after 6 years. Furthermore, the neutralization antibodies to the vaccinal antigens have been detected in the cervical mucus of vaccinated women. The preliminary data are now available showing the presence of HPV-specific antibodies in the oral cavity in women after vaccination. The level of antibodies has been dependent on time since vaccination.
