Note: Bivalent HPV vaccine has been discontinued from the US market; other HPV vaccines should be used for immunization. According to ACIP, doses administered ≤4 days before minimum interval or age are considered valid; however, local or state mandates may supersede this timeframe (ACIP [Kroger 2021]).
Primary immunization:
CDC (ACIP) recommendations: In a 2-dose series, the minimum interval between the first and second dose is 5 months. In a 3-dose schedule, minimum interval between first and second doses is 4 weeks; the minimum interval between the second and third dose is 12 weeks; the minimum interval between first and third doses is 5 months (CDC/ACIP [Meites 2016])
Non-immunocompromised patients and certain specified medical conditions: Asplenia, asthma, chronic granulomatous disease, chronic liver disease, chronic lung disease, chronic renal disease, central nervous system anatomic barrier defects (eg, cochlear implant), complement deficiency, diabetes, heart disease, or sickle cell disease:
Children ≥9 years and Adolescents <15 years: Females: 2-dose series: IM: 0.5 mL at 0, and 6 to 12 months. Administer first dose at age 11 to 12 years; for patients with any history of sexual abuse or assault, vaccination should be started at 9 years of age
Adolescents ≥15 years: Females: 3-dose series: IM: 0.5 mL at 0, 1 to 2, and 6 months
Immunocompromised patients including those with immunocompromising conditions that might reduce cell-mediated or humoral immunity, such as B lymphocyte antibody deficiencies, T lymphocyte complete or partial defects, HIV infection, malignant neoplasms, transplantation, autoimmune disease, or immunosuppressive therapy): Children ≥9 years and Adolescents: Females: 3-dose series: IM: 0.5 mL at 0, 1 to 2, and 6 months
Manufacturer's labeling: Females: Children ≥9 years and Adolescents: IM: 0.5 mL per dose for a total of 3 doses. Administer the second and third doses at 1 and 6 months after initial dose.
Catch-up immunization: CDC (ACIP) recommendations (Meites 2016): Note: Do not restart the series. If doses have been given, begin the below schedule at the applicable dose number. Children ≥9 years and Adolescents: IM: 0.5 mL per dose for a total of 2 to 3 doses (See CDC/ACIP recommendations above for 2-dose vs 3-dose schedule criteria):
First dose given on the elected date
Second dose given at least 4 weeks after the first dose (for 3-dose schedule) or 5 months after the first dose (for a 2-dose schedule)
Third dose (for a 3-dose schedule) given at least 12 weeks after the second dose and at least 5 months after the first dose

Injection, suspension [preservative free]:
Cervarix: HPV 16 L1 protein 20 mcg and HPV 18 L1 protein 20 mcg per 0.5 mL (0.5 mL) [contains aluminum, rubber in prefilled syringe; manufactured using Trichoplusia ni (insect cells)]
IM: Shake suspension well prior to use; do not use suspension if it is discolored or contains particulate matter; should be a homogenous, turbid, white suspension. Do not dilute or mix with other vaccines. Administer IM into the deltoid region of the upper arm; not for IV, intradermal, or SubQ administration. Do not mix with other vaccines or injections; separate needles and syringes should be used for each injection (ACIP [Kroger 2021]). To prevent syncope related injuries, adolescents should be vaccinated while seated or lying down (ACIP [Kroger 2021]). US law requires that the date of administration, the vaccine manufacturer, lot number of vaccine, and the administering person’s name, title and address be entered into the patient’s permanent medical record.
For patients at risk of hemorrhage following intramuscular injection, the vaccine should be administered intramuscularly if, in the opinion of the physician familiar with the patient's bleeding risk, the vaccine can be administered by this route with reasonable safety. If the patient receives antihemophilia or other similar therapy, intramuscular vaccination can be scheduled shortly after such therapy is administered. A fine needle (23-gauge or smaller) should be used for the vaccination and firm pressure on the site (without rubbing) for at least 2 minutes. The patient should be instructed concerning the risk of hematoma from the injection. Patients on anticoagulant therapy should be considered to have the same bleeding risks and treated as those with clotting factor disorders (ACIP [Kroger 2021]).
IM: Shake well prior to use. Do not use if discolored or if containing particulate matter, or if syringe is cracked. Inject IM into the deltoid region of the upper arm. Do not administer IV, SubQ, or intradermally. Do not mix with other vaccines or injections; separate needles and syringes should be used for each injection. To prevent syncope related injuries, patients should be vaccinated while seated or lying down. When given with other age appropriate vaccines, human papillomavirus vaccine should be given after other vaccines because it may cause more pain with injection (NACI 2017).
For patients at risk of hemorrhage following intramuscular injection, the vaccine should be administered intramuscularly if, in the opinion of the physician familiar with the patient's bleeding risk, the vaccine can be administered by this route with reasonable safety. If the patient receives antihemophilia or other similar therapy, intramuscular vaccination can be scheduled shortly after such therapy is administered (ACIP [Kroger 2021]). A fine needle (23 gauge or smaller) can be used for the vaccination and firm pressure applied to the site (without rubbing) for 5 to 10 minutes (NACI 2017). The patient should be instructed concerning the risk of hematoma from the injection. Patients on anticoagulant therapy should be considered to have the same bleeding risks and treated as those with clotting factor disorders (ACIP [Kroger 2021]; NACI 2017).
Store under refrigeration at 2°C to 8°C (36°F to 46°F); do not freeze. Store in original package to protect from light. Administer as soon as possible after removing from refrigeration. Stable for up to 3 days when stored between 8°C and 25°C (46°F to 77°F) or for up to 1 day when stored at 25°C to 37°C (77°F to 99°F). Discard if exposed to >37°C (99°F). May develop a fine, white deposit with a clear, colorless supernatant during storage (not a sign of deterioration).
Prevention of cervical cancer and cervical intraepithelial neoplasia with or without cervical adenocarcinoma in situ caused by Human Papillomavirus (HPV) types 16 and 18 (FDA approved in girls ≥9 years and women ≤25 years of age)
The Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination for females 11 to 12 years of age; for patients with any history of sexual abuse or assault, vaccination should be started at 9 years of age. Catch-up vaccination is recommended for females 13 to 26 years of age (CDC/ACIP [Meites 2016]).

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.
>10%:
Central nervous system: Fatigue (55%)
Local: Pain at injection site (92%), erythema at injection site (48%), swelling at injection site (44%)
Neuromuscular & skeletal: Myalgia (49%), arthralgia (21%)
1% to 10%:
Dermatologic: Urticaria (7%), injection site pruritus (1%)
Genitourinary: Vaginal infection (1%)
Infection: Influenza (3%), infection (chlamydia: 2%)
Respiratory: Nasopharyngitis (4%), pharyngolaryngeal pain (3%), pharyngitis (2%)
<1%, postmarketing, and/or case reports: Anaphylactoid reaction, anaphylaxis, angioedema, erythema multiforme, hypersensitivity reaction, induration at injection site, lymphadenopathy, paresthesia (local), syncope (may be associated with tonic-clonic movements), vasodepressor syncope
Hypersensitivity to any component of the formulation
Concerns related to adverse effects:
• Anaphylactoid/hypersensitivity reactions: Immediate treatment (including epinephrine 1 mg/mL) for anaphylactoid and/or hypersensitivity reactions should be available during vaccine use (NACI 2017).
• Shoulder injury related to vaccine administration: Vaccine administration that is too high on the upper arm may cause shoulder injury (eg, shoulder bursitis, tendinitis) resulting in shoulder pain and reduced range of motion following injection. Use proper injection technique for vaccines administered in the deltoid muscle (eg, injecting in the central, thickest part of the muscle) to reduce the risk of shoulder injury related to vaccine administration (Cross 2016; Foster 2013).
• Syncope: Syncope has been reported with use of injectable vaccines and may result in serious secondary injury (eg, skull fracture, cerebral hemorrhage); typically reported in adolescents and young adults and within 15 minutes after vaccination. Procedures should be in place to avoid injuries from falling and to restore cerebral perfusion if syncope occurs (ACIP [Kroger 2021]; NACI 2017).
Disease-related concerns:
• Acute illness: The decision to administer or delay vaccination because of current or recent febrile illness depends on the severity of symptoms and the etiology of the disease. Defer administration in patients with moderate or severe acute illness (with or without fever); vaccination should not be delayed for patients with mild acute illness (with or without fever) (NACI 2017).
• Bleeding disorders: Use with caution in patients with a history of bleeding disorders (including thrombocytopenia); bleeding/hematoma may occur from IM administration; if the patient receives antihemophilia or other similar therapy, IM injection can be scheduled shortly after such therapy is administered (ACIP [Kroger 2021]; NACI 2017).
• Human papillomavirus (HPV) infection: There is no evidence that individuals already exposed to or infected with HPV will be protected; those already infected with 1 or more HPV types were protected from disease in the remaining HPV types. Will not provide therapeutic benefit for active HPV disease or abnormal Pap test; will not protect against diseases not caused by HPV vaccine types 16 and 18.
Concurrent drug therapy issues:
• Anticoagulant therapy: Use with caution in patients receiving anticoagulant therapy; bleeding/hematoma may occur from IM administration (ACIP [Kroger 2021]).
• Vaccines: In order to maximize vaccination rates, simultaneous administration (ie, >1 vaccine on the same day at different anatomic sites) is recommended of all age-appropriate vaccines (live or inactivated) for which a person is eligible at a single clinic visit, unless contraindications exist. The NACI prefers each dose in a HPV vaccine series be the same vaccine when possible; however, if the previous vaccine is not known then any of the HPV vaccines licensed for use in Canada may be used (NACI 2017).
Special populations:
• Altered immunocompetence: Consider deferring immunization during periods of severe immunosuppression (eg, patients receiving chemo/radiation therapy or other immunosuppressive therapy [including high-dose corticosteroids]); may have a reduced response to vaccination (NACI 2017). In general, household and close contacts of persons with altered immunocompetence may receive all age appropriate vaccines. Inactivated vaccines should be administered ≥2 weeks prior to planned immunosuppression when feasible; inactivated vaccines administered during chemotherapy should be readministered after immune competence is regained (ACIP [Kroger 2021]; IDSA [Rubin 2014]; NACI 2017).
• Males: Not approved for use in males.
Other warnings/precautions:
• Effective immunity: Vaccination may not result in effective immunity in all patients. Response depends upon multiple factors (eg, type of vaccine, age of patient) and may be improved by administering the vaccine at the recommended dose, route, and interval. Vaccines may not be effective if administered during periods of altered immune competence (NACI 2017).
None known.
Acetaminophen: May diminish the therapeutic effect of Vaccines. Management: Consider avoiding routine prophylactic use of acetaminophen before or during vaccine administration when possible. Acetaminophen is still recommended to treat fevers and/or pain that occurs after vaccination. Risk D: Consider therapy modification
Corticosteroids (Systemic): May diminish the therapeutic effect of Vaccines (Inactivated). Management: Administer vaccines at least 2 weeks prior to immunosuppressive corticosteroids if possible. If patients are vaccinated less than 14 days prior to or during such therapy, repeat vaccination at least 3 months after therapy if immunocompetence restored. Risk D: Consider therapy modification
Fingolimod: May diminish the therapeutic effect of Vaccines (Inactivated). Management: Vaccine efficacy may be reduced. Complete all age-appropriate vaccinations at least 2 weeks prior to starting fingolimod. If vaccinated during fingolimod therapy, revaccinate 2 to 3 months after fingolimod discontinuation. Risk D: Consider therapy modification
Immunosuppressants (Cytotoxic Chemotherapy): May diminish the therapeutic effect of Vaccines (Inactivated). Management: Give inactivated vaccines at least 2 weeks prior to initiation of chemotherapy when possible. Patients vaccinated less than 14 days before initiating or during chemotherapy should be revaccinated at least 3 months after therapy is complete. Risk D: Consider therapy modification
Immunosuppressants (Miscellaneous Oncologic Agents): May diminish the therapeutic effect of Vaccines (Inactivated). Management: Give inactivated vaccines at least 2 weeks prior to initiation of immunosuppressants when possible. Patients vaccinated less than 14 days before initiating or during therapy should be revaccinated at least 3 after therapy is complete. Risk D: Consider therapy modification
Immunosuppressants (Therapeutic Immunosuppressant Agents): May diminish the therapeutic effect of Vaccines (Inactivated). Management: Give inactivated vaccines at least 2 weeks prior to initiation of immunosuppressants when possible. Patients vaccinated less than 14 days before initiating or during therapy should be revaccinated at least 2 to 3 months after therapy is complete. Risk D: Consider therapy modification
Methotrexate: May diminish the therapeutic effect of Vaccines (Inactivated). Management: Administer vaccines at least 2 weeks prior to methotrexate initiation, if possible. If patients are vaccinated less than 14 days prior to or during methotrexate therapy, repeat vaccination at least 3 months after therapy if immunocompetence restored. Risk D: Consider therapy modification
Propacetamol: May diminish the therapeutic effect of Vaccines. Management: Consider avoiding routine prophylactic use of propacetamol before or during vaccine administration when possible. Propacetamol is still recommended to treat fevers and/or pain that occurs after vaccination. Risk D: Consider therapy modification
RiTUXimab: May diminish the therapeutic effect of Vaccines (Inactivated). Management: Give inactivated vaccines at least 2 weeks prior to initiation of rituximab when possible. Patients vaccinated less than 14 days before initiating or during therapy should be revaccinated at least 6 months after therapy is complete. Risk D: Consider therapy modification
Siponimod: May diminish the therapeutic effect of Vaccines (Inactivated). Management: Avoid administration of vaccines (inactivated) during treatment with siponimod and for 1 month after discontinuation due to potential decreased vaccine efficacy. Risk D: Consider therapy modification
The manufacturer recommends pregnancy be avoided for 2 months following vaccination.
Administration of the human papillomavirus vaccine during pregnancy is not recommended. Although exposure to human papillomavirus vaccine has not been causally associated with adverse pregnancy outcomes, until additional information is available the vaccine series (or completion of the series) should be delayed until pregnancy is completed (NACI 2017).
Exposures to bivalent human papillomavirus vaccine during pregnancy should be reported to the manufacturer (800-387-7374).
Gynecologic screening exam, papillomavirus test as per current guidelines; screening for HPV is not required prior to vaccination and screening for cervical cancer should continue as recommended following vaccination (ACIP [Kroger 2021]). Observe for syncope for 15 minutes following administration. If seizure-like activity associated with syncope occurs, maintain patient in supine or Trendelenburg position to reestablish adequate cerebral perfusion.
Contains inactive human papillomavirus (HPV) proteins HPV 16 L1, and HPV 18 L1 which produce neutralizing antibodies to prevent cervical cancer, cervical adenocarcinoma, and cervical neoplasia cause by HPV.
Efficacy: HPV2 has shown to be 95% to 99% effective against HPV types 16 and 18-related cervical disease in females 15 to 25 years of age. In addition, vaccination against HPV types 16 and 18 may prevent ~70% of anogenital cancers and 60% of high-risk precancerous cervical lesions (NACI 2017).
Onset: Seroconversion was observed at month 7
Duration: Unknown. Clinical studies followed HPV2 vaccinated participants for 10 years and found no evidence of waning protection (NACI 2017).
Comparison of HPV vaccines: Cervarix and Gardasil are both vaccines formulated to protect against infection with the human papillomavirus. Both are inactive vaccines which contain proteins HPV16 L1 and HPV 18 L1, the cause of >70% of invasive cervical cancer. The vaccines differ in that Gardasil also contains HPV 6 L1 and HPV 11 L1 proteins which protect against 75% to 90% of genital warts. The vaccines also differ in their preparation and adjuvants used. The viral proteins in Cervarix are prepared using Trichoplusia ni (insect cells) which are adsorbed onto an aluminum salt which is also combined with a monophosphoryl lipid. The viral proteins in Gardasil are prepared using S. cerevisiae (baker's yeast) which are then adsorbed onto an aluminum salt. Results from a short-term study (measurements obtained 1 month following the third vaccination in the series) have shown that the immune response to HPV 16 and HPV 18 may be greater with Cervarix; although the clinical significance of these differences is not known, local adverse events may also occur more frequently with this preparation. Both vaccines are effective and results from long-term studies are pending (Einstein 2009).
