Indications
- Prevention of premalignant anogenital lesions, mainly of the cervix, and of cervical cancer due to certain types of papillomavirus.
- Prevention of anogenital warts due to certain papillomavirus types, particularly 6 and 11, for the quadrivalent vaccine.
Composition, forms, route of administration
- Recombinant bivalent vaccine against HPV types 16 and 18 or quadrivalent vaccine against HPV types 6, 11, 16, and 18.
- Suspension for injection in monodose or multidose vials, only for the bivalent vaccine, for IM injection into the deltoid muscle.
Dose and vaccination schedule
Child from 9 to 14 years
- 2 doses of 0.5 ml at least 6 months apart.
- If the 2 doses are administered less than 5 months apart, a third dose is administered at least 6 months and up to 12 months after the first dose.
Immunocompromised or HIV-infected individuals
- 2 doses of 0.5 ml 1 or 2 months apart then a third dose 6 months after the first dose.
Additional note
- Most vaccination programmes only target young females because they are the group most at risk of papillomavirus complications.
- High vaccination coverage in girls reduces the risk of infection for boys. For vaccination of boys, follow national recommendations.
- In individuals 15 years and over, the vaccine is administered in 3 doses as in immunocompromised individuals.
Contra-indications, adverse effects, precautions
- Do not administer in the event of allergic reactions to a previous dose of papillomavirus vaccine.
- Vaccination should be postponed in the event of severe acute febrile illness; minor infections are not contra-indications.
- May cause mild reactions at the injection site, fever, headache, myalgia, and rarely post-vaccination syncope or anaphylactic reactions.
- If administered simultaneously with other vaccines, use different syringes and injection sites.
- Pregnancy: avoid.
- Breast-feeding: no contra-indication.
- Shake before use to homogenise the vaccine.
