NOTE: According to U.S. federal laws, the health care provider must record in the patient's permanent record the manufacturer, lot number, administration date, and the name and address of the person administering the vaccine.
Inform the patient, parent, guardian, or responsible adult of the benefits and risks of the vaccine. Provide the Vaccine Information Statements from the manufacturer to the recipient or guardian before each immunization. The action is required by the National Childhood Vaccine Injury Act of 1986.
If a human papillomavirus (HPV) vaccine has been previously given, question the patient, parent, or guardian about any symptoms or signs of an adverse reaction.
Complete a Vaccine Adverse Event Reporting System (VAERS) report form if adverse events have been identified. The reporting of events is required by the National Childhood Vaccine Injury Act of 1986. The toll-free number for VAERS is 1—800—822—7967. Also, report an adverse event to the manufacturer. Depending on the adverse reaction, a subsequent dose may be contraindicated.
Health care professionals administering vaccines should take appropriate precautions to prevent allergic reactions in vaccine recipients. The health care professional should have immediate availability of epinephrine (1:1000) injection and other agents used in the treatment of severe anaphylaxis in the event of a serious allergic reaction.
Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. Following vigorous shaking, the vaccine is a cloudy white suspension. If discoloration or visible particulate matter are present, discard the vaccine dose.
Do not mix with any other vaccine or product in the same syringe.
Use the vaccine as supplied; no dilution or reconstitution is necessary.
Shake well before use. Thorough agitation immediately before administration is necessary to maintain suspension of the vaccine.
Single-dose vial: Using a sterile needle and syringe, withdraw the 0.5 ml dose and administer immediately.
Prefilled syringe: Attach a sterile needle by twisting in a clockwise direction. Administer entire dose contained within the syringe.
Prior to administration, clean skin over the injection site with a suitable cleansing agent.
The preferred injection site is the deltoid region of the upper arm or in the higher anterolateral area of the thigh. Do NOT inject into the gluteal area or other areas where there may be a major nerve trunk.
Carefully observe patients for approximately 15 minutes after administration of the vaccine; syncope may occur.
Storage of unopened vials: Store refrigerated at 2—8 degrees C (36 to 46 degrees F); do not freeze. Administer as soon as possible after being removed from refrigeration. The vaccine can remain outside of refrigeration at temperatures up to 25 degrees C (77 degrees F) for a total cumulative time of not more than 72 hours.

Ocrelizumab: (Moderate) Administer all non-live vaccines at least 2 weeks before ocrelizumab initiation, whenever possible. Ocrelizumab may interfere with the effectiveness of non-live virus vaccines. Attenuated antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide and pneumococcal conjugate vaccines, and seasonal influenza vaccine were observed in patients exposed to ocrelizumab at the time of vaccination during an open-label study. Infants born to mothers exposed to ocrelizumab during pregnancy may receive non-live vaccines as indicated before B-cell recovery; however, consider assessing the immune response to the vaccine. ACIP recommends that patients receiving any vaccination during immunosuppressive therapy or in the 2 weeks prior to starting therapy should be considered unimmunized and should be revaccinated a minimum of 3 months after discontinuation of therapy. Passive immunoprophylaxis with immune globulins may be indicated for immunocompromised persons instead of, or in addition to, vaccination.

Mechanism Of Action
The human papillomavirus (HPV) only infects humans. An infection from this virus can cause squamous cell cervical cancer and cervical adenocarcinoma and their precursor lesions, which are cervical intraepithelial neoplasia (CIN) 1, 2, and 3 and adenocarcinoma in situ (AIS), respectively. HPV also causes anal cancer, vulvar cancer, vaginal cancer, and genital warts (condyloma acuminata), which are growths of the cervicovaginal, vulvar, and the external genitalia that rarely progress to cancer. The HPV 6, 11, 16, and 18 types cause 35—50% of all CIN 1, VIN 1, and VaIN 1 cases and 90% of genital wart cases. Further, the HPV 16 and 18 types cause approximately 70% of cervical cancer, AIS, CIN 3, VIN 2/3, and VaIN 2/3 cases and 50% of CIN 2 cases.
The exact mechanism by which the HPV quadrivalent vaccine protects against type-specific HPV infection and sequela is unknown. Receipt of the HPV quadrivalent vaccine is thought to result in a humoral immune response directed against HPV-L1 capsid proteins. The vaccine contains recombinant L1 protein, which is the major antigenic protein of the capsid of HPV types 6, 11, 16, and 18. These L1 proteins are produced in brewers yeast (i.e., Saccharomyces cerevisiae), purified, and adsorbed on an aluminum-containing adjuvant (amorphous aluminium hydroxyphosphate sulfate or AAHS).
Efficacy of the 3-dose HPV quadrivalent vaccine series was established through 6 clinical studies involving a total of 28,413 vaccine recipients (20,541 females ages 16—26 years; 4055 males ages 16—26; 3817 women ages 25—45 years). The percentage of study participants who were naive to all 4 vaccine HPV types at baseline include 73% of females ages 16—26 years, 83% of males ages 16—26 years, and 67% of women ages 24—45 years. Data from these studies found the vaccine to be more than 93% efficacious in preventing cervical and genital diseases associated with HPV type 6, 11, 16 and 18 in females aged 16—26 years who were HPV naive at baseline. In HPV naive women aged 24—45 years, the vaccine was found to be 80.5% (95% CI: 68.3, 88.6) effective in preventing persistent infection, 85.8% (95% CI: 52.4, 97.3) effective in preventing cervical intraepithelial neoplasia (any grade), and 87.6% (95% CI: 7.3, 99.7) effective in preventing genital warts. The vaccine was also effective in HPV naive males (age 16—26 years) in reducing anal intraepithelial neoplasia related to all 4 HPV types and genital warts related to HPV type 6 and 11. However, evident to suggest vaccine efficacy in individuals previously exposed to HPV type 6, 11, 16 or 18 is not available. In addition, the vaccine was not found to provide cross-protection against HPV types not contained within the vaccine, nor was it found to protect against genital diseases not related to HPV.
The long-term protection of the HPV quadrivalent vaccine continues to be studied. Two extension studies have reported data regarding the long-term protection of the HPV quadrivalent vaccine against HPV-related disease. In a trial including 1902 females 16—23 years of age who completed the 3-dose vaccination series, the median follow-up from initial vaccination was 6.7 years (2.8—8.4 years). No cases of HPV 6-, 11-, 16-, or 18-related CIN, AIS, cervical cancer, vulvar cancer, or vaginal cancer were observed over a total of 5765 person-years at risk. In an extension of a Phase 3 study, including 246 girls and 168 boys who completed the HPV quadrivalent vaccine series, the mean follow-up from the first dose of vaccine was 7.2 years (0.5—8.5 years). No cases of persistent infection of at least 12 months’ duration and no cases of HPV 6-, 11-, 16-, or 18-related CIN, AIS, VIN, VaIN, cervical cancer, vulvar cancer, vaginal cancer, or genital lesions were observed over a total 1105 person-years at risk. There were 4 cases of HPV 6-, 11-, 16-, or 18-related persistent infection of at least 6 months’ duration, including 3 cases related to HPV 16 and 1 case related to HPV 6, none of which persisted to 12 months’ duration.
Inoculation with the HPV quadrivalent vaccine elicited detectable antibody concentrations to HPV type 6, 11, 16, and 18. Most vaccine recipients (> 97%) are seropositive for all 4 HPV types at 1 month after the third dose; however, the minimum anti-HPV titer that confers protective efficacy has not been determined. After the 3-doses vaccine series, geometric mean titers for anti-HPV 6, anti-HPV 11, anti-HPV 16, and anti-HPV 18 peaked at month 7, declined through month 24, and stabilized through month 36 at levels above baseline; titers at month 60 were similar to those observed at month 24 for all 4 HPV types. The interim reports of 2 extension studies included analysis of type-specific anti-HPV antibody titers at 9 years postdose 1 for girls and women 16 through 23 years of age and at 8 years postdose 1 for boys and girls 9 through 15 years of age at enrollment. The proportions of seropositive subjects ranged from 88.4% to 94.4% for anti-HPV 6, from 89.1% to 95.5% for anti-HPV 11, from 96.8% to 99.1% for anti-HPV 16, and from 60.0% to 64.1% for anti-HPV 18.
The human papillomavirus (HPV) quadrivalent vaccine is administered intramuscularly. Vaccination does not ensure immunity. Distrubution, metabolism, and excretion of the vaccine have not been defined.
During clinical trials, immunogenicity of the HPV quadrivalent vaccine was evaluated in 12,634 females (age 9 to 45 years) and 3,109 males (age 9 to 45 years). Immunity was determine by measuring geometric mean titers for each of the 4 HPV type, and determining the percentage of vaccine recipients who were seropositive for antibodies against those HPV types. Overall, a seropositive immune response was observed in more than 99% of females (age 16 to 26 years), more than 97% of women (age 27 to 45 years), and more than 97% of males (age 16 to 26 years). In all three groups, immunity was assessed 1 month after the third vaccine dose. Geometric mean titer peak at month 7, declined through month 24, then stabilize through month 36 at levels above baseline; titers at month 60 are similar to those observed at month 24 for all 4 HPV types. The interim reports of 2 extension studies included analysis of type-specific anti-HPV antibody titers at 9 years post-dose 1 for girls and women 16 through 23 years of age and at 8 years post-dose 1 for boys and girls 9 through 15 years of age at enrollment. The proportions of seropositive subjects ranged from 88.4% to 94.4% for anti-HPV 6, from 89.1% to 95.5% for anti-HPV 11, from 96.8% to 99.1% for anti-HPV 16, and from 60.0% to 64.1% for anti-HPV 18.
Pregnancy And Lactation
The human papillomavirus quadrivalent vaccine is rated FDA pregnancy risk category B. No adequate and well controlled studies have been conducted in pregnant women, and it is unknown whether this vaccine can cause fetal harm or affect reproductive capacity. If a woman is found to be pregnant after initiating the vaccination series, the remainder of the 3-dose regimen should be delayed until after completion of the pregnancy. In clinical trials, women were tested for pregnancy before each dose. Completion of a pregnant woman's vaccination regimen was deferred until pregnancy resolution. Overall 1,973 women were exposed to the vaccine during pregnancy, with 22.6% (n = 446/1,973) experiencing an adverse outcome (i.e., spontaneous abortion, late fetal death, congenital anomaly). This rate was less than in women who received the placebo control 23.1% (n = 460/1,994). For congenital anomalies specifically, 45 cases occurred in recipients of the vaccine compared to 34 cases with the placebo control. The majority of these cases had an onset of greater than 30 days post-dose (40 cases vaccine, 33 cases placebo control). The anomalies that occurred with an estimated onset within 30 days of vaccination (n= 5) included pyloric stenosis, congenital megacolon, congenital hydronephrosis, hip dysplasia, and club foot. The manufacturer recommends administration of the vaccine during pregnancy only if clearly needed. Vaccinees and health care providers are encouraged to report any exposure to the vaccine during pregnancy by calling 1—877—888—4231 or 1—800—822—7967.
Data are limited regarding use of the human papillomavirus quadrivalent vaccine during breast-feeding and its excretion in human milk is unknown. During clinical studies, a total of 582 infants were breast-fed during the period in which their mothers were vaccinated. Of those infants, 4.6% (n = 27) experiencing a serious adverse reactions, with 7 of these reactions (acute respiratory illness) occurring within 30 days of the maternal vaccination. The manufacturer recommends caution when administering to nursing women; however, according the Advisory Committee on Immunization Practices (ACIP), vaccines administered to a lactating woman do not affect the safety of breast-feeding. In addition, breast-feeding does not adversely affect immunization and is not a contraindication for any inactivated recombinant vaccine. In fact, limited data suggest breast-feeding may enhance the immune response to certain antigens. Also, no serious adverse events in a breast-fed infant have been associated with the use of an inactivated recombinant vaccine. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, health care providers are encouraged to report the adverse effect to the FDA.
