It is used for preventing the following diseases caused by oncogenic human papillomavirus (HPV) types 16 and/or 18- Cervical cancer Cervical intraepithelial neoplasia Grade 2 or 3 (CIN2/3) and adenocarcinoma in-situ (AIS) Cervical intraepithelial neoplasia Grade 1 (CIN1) and persistent infections of HPV types 16 and/or 18 The risk of exposure to HPV increases with age, especially with sexual debut. Therefore, it is recommended to vaccinate as early as possible. It would be more beneficial to receive the vaccine at the earlier time between ages 9-45 years.

Each 0.5 ml contains Human Papillomavirus Vaccine (rDNA) BP consisting of- Recombinant human papillomavirus type 16 L1 protein 40 µg Recombinant human papillomavirus type 18 L1 protein 20 µg This is a mixture of two-aluminum hydroxide adjuvant-absorbed recombinant L1 capsid proteins of human papillomavirus (HPV) type-16 and type-18 each self-assembled into virus-like particles (VLPs). The HPV-16 and HPV-18 L1 antigens are expressed in Escherichia coli by recombinant DNA technology.

Vaccines, Anti-sera & Immunoglobulin

Human Papillomavirus (HPV) type 16 and 18 cause about 70% of cervical cancer. HPV bivalent (types 16 and 18) vaccine is a non-infectious vaccine produced by recombinant technology, which contains virus-like particles (VLP) of the major capsid LI protein of oncogenic HPV types 16 and 18. Efficacy of vaccine may be mediated by the production of IgG neutralizing antibodies against the HPV-L1 capsid proteins.

Adult: Females 10-25 yr (or between 10-45 yr in some countries): 3 doses of 0.5 ml each given at 0,1 and 6 mth, preferably administered into deltoid muscle.Child: Not recommended for use in girls beiow 9 yr of age.

It is recommended to receive 3 doses of 0.5-ml each, by intramuscular injection according to the following schedule: 0, 1, and 6 months.  If flexibility in the vaccination schedule is necessary, the second dose can be administered between 1 month and 2 months after the first dose and third dose between 5 and 8 months after the first dose. On the basis of the clinical trial results and refer to the recommendations in Human Papillomavirus Vaccines: WHO Position Paper (2017), female aged 9-14 years can also choose a vaccination schedule of two doses at 0 month and 6 month (0.5-ml per dose, with an interval of not less than 5 months). At present, it has not been determined whether the booster vaccination is required. Immunization consists of 3 doses of 0.5-ml each, by intramuscular injection according to the following schedule: 0, 1, and 6 months. The preferred site of administration is the deltoid region of the upper arm. There has been no data on subcutaneous injection. Intravascular or intradermal injection is prohibited The content of the prefilled syringe should be inspected visually both before and after shaking for any foreign particulate matter and/or abnormal physical appearance prior to administration. In the event of either being observed, discard the vaccine. The vaccine should be shaken well before use, and it should be a white homogeneous suspension after shaking. It should be vaccinated as soon as possible after removal from the refrigeration container. The full-recommended dose of the vaccine should be used. Any prefilled syringe with crack, label unclear or invalid and vaccine with abnormal appearance should not be used.

Co-administration: There are no data to assess the concomitant use of HPV vaccine with other vaccines. Do not mix it with any other vaccine in the same syringe or vial. Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids (used in greater than physiologic doses), may reduce the immune response to Human papillomavirus bivalent (Types 16 and 18) vaccine. The use of immunoglobulin or blood products should be avoided within 3 months prior to the vaccination of HPV vaccine. There has been no clinical evidence available to demonstrate whether the use of hormonal contraceptives will affect the preventive effect of HPV vaccine. Like other vaccines, vaccination of HPV vaccine in immunocompromised people may not induce adequate immune response. Concomitant use with immunosuppressive agents may not induce an optimal active immune response. At present, there has been no clinical data available to support the interchangeable use among HPV vaccines. The injection of HPV vaccine combined with other medicinal products is prohibited.

Immunosuppressive therapies e.g. irradiation, cytotoxic drugs and corticorsteroids may reduce a patient's immune response to the vaccine.

Hypersensitivity to the active substances or to any component of the excipients of vaccine. Individuals who develop symptoms indicative of hypersensitivity after receiving a dose of this vaccine.

Human papillomavirus bivalent (Types 16 and 18) vaccine is generally well tolerated. The most common local adverse reactions were pain, redness, and swelling at the injection site. The most common general adverse events were fatigue, headache, myalgia, gastrointestinal symptoms, and arthralgia.Systemic Adverse Reactions: Very common: Fever (≥37.1°C) Common: Headache, fatigue, cough, muscle pain, nausea, diarrhea, dizziness and vomiting Occasional: Hypersensitivity, allergic dermatitis, rash, dizziness and pruritus. Local Adverse Reactions: Very common: Pain at the injection site Common: Pruritus, induration, swelling and erythema at injection site Occasional: Rash and discomfort at injection site. Most of the above adverse reactions are mild to moderate

Pregnancy Category- B. Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women OR Animal studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.

Vaccination cannot replace the routine cervical cancer screening or other measures to prevent HPV infection and sexually transmitted diseases. Therefore, routine cervical cancer screening remains extremely important as recommended by the relevant health administrative departments.Prior to the vaccination, medical personnel should inquire and review the vaccinee's medical history (especially the prior vaccination history and any prior adverse reaction related to vaccination), and conduct clinical examination to evaluate the benefits and risks of vaccination.It is not recommended for populations other than those described in of the package insert.Like other vaccines for injection, appropriate medical emergency measures and monitoring methods should be prepared to ensure that those who develop allergic reactions after the injectionSyncope (fainting) may occur after any dose of vaccine, leading to falls and injuries, especially in adolescents and young adults. Therefore, it is recommended that the observation on site be conducted for at least 30 minutes after each injection as required in the vaccination procedures.It has been reported that syncope associated with tonic-clonic seizures and other epileptiform seizures may occur after the vaccination with similar products overseas. Syncope associated with tonic-clonic seizures is usually transient, and it can be resolved spontaneously when the vaccinee is placed in a supine or head-down position and the cerebral perfusion is restored. Some vaccinees may experience psychogenic reactions before/after the vaccination, and measures should be taken to avoid injury from the syncope.Like other vaccines, the vaccination should be postponed in vaccinees with acute serious febrile illness. In case of current or recent fever symptoms, whether to postpone the vaccination depends mainly on the severity of the symptoms and their etiology. Low-grade fever and mild upper respiratory tract infection are not absolute contraindications to vaccination.The vaccine should be used with caution in vaccinees with thrombocytopenia or any coagulation disorder.Like any other vaccine, vaccination with HPV vaccine may not ensure the protective effect for all vaccinees.It is only used for preventive purposes, but not indicated for the treatment of existing HPV-related lesions or preventing the progression of lesions.It cannot prevent lesions caused by all high-risk types HPV infections. It has not been proved that it can prevent the lesions caused by the infection of non-vaccine types of HPV as well as the diseases not caused by HPV infection.There has been no data on the use of HPV vaccine in vaccinees with impaired immune system (such as receiving the medication of immunosuppressive agents). Like other vaccines, vaccination in immunocompromised people may not induce adequate immune response.

Keep out of the reach and sight of children. Store at +2ºC to +8ºC. Transportation should also be at +2ºC to +8ºC. Do not freeze. Discard vaccine if frozen. Protect from light.

Vaccines, Anti-sera & Immunoglobulin

Pregnancy: At present, there has been no independent study conducted to systematically evaluate the effect on pregnant women. The very limited data from the clinical trial showed that the accidental vaccination during pregnancy does not cause abnormal pregnancy outcomes and neonatal health conditions, and no adverse effects on pregnancy rate, pregnancy outcomes and neonatal health conditions were observed after the vaccination of HPV vaccine. However, the data are not sufficient to determine whether pregnant women are at risk of adverse pregnancy (including spontaneous abortion) after the vaccination. In animal experiments, no direct or indirect adverse effects on reproduction, pregnancy, embryo/fetus development, parturition or postnatal development are observed after the vaccination. Vaccination should be avoided during pregnancy. If a woman is pregnant or preparing for pregnancy, it is recommended to postpone or interrupt the vaccination procedure, and the vaccination can be conducted after the end of pregnancy.Lactation: There has been no relevant study data to HPV vaccine. As many drugs can be secreted in breast milk, HPV vaccine should be used with caution in lactating women.
