How do you determine a girl’s eligibility for HPV vaccine? 2 What to do when…? 3 What are the precautions and contraindications? 4 Explain to the participants the key issues raised in this module: What is the schedule and dosage for CervarixTM? How do you determine a girl’s eligibility for HPV vaccine? What to do when…? What are the precautions and contraindications?
What is the schedule for CervarixTM, vaccine administration? Example schedule Dose 1 Dose 2 Minimum interval of 6 months HPV vaccine, CervarixTM, is a 2 dose schedule with a minimum interval of 6 months between the first and second dose. Each dose is administered intramuscularly using 0.5ml of liquid suspension The second dose is at least 6 months after the first dose Attention: if second dose is administered too early (prior to 6 month interval) then a third dose will be needed to achieve full protection. The third dose should be given at least 6 months after the first dose
Who should get HPV vaccine? Ask the audience to point to the image of girls who they think should get HPV vaccine. The answer will appear by a mouse click in animations. Pic 1: The target population for HPV vaccination are girls who are 9 – 13 years old Pic 2: The vaccines are not recommended for girls younger than 9 years of age For the HPV vaccine to work best, it is very important for preteens to get all 2 doses (shots) long before any sexual activity with another person begins. It is possible to be infected with HPV the very first time that a person has sexual contact with another person. Also, the vaccine produces higher antibody levels when given at early age compared to older ages
Are there contraindications to HPV vaccination? HPV vaccine is not recommended for: SEVERE FEBRILE ILLNESS Pic 1: HPV vaccines are not recommended for use in people who have experienced severe allergic reactions after a previous vaccine dose, or to a component of the vaccine (for example, yeast in CervarixTM) Pic 2: HPV vaccines are not recommended for use in pregnancy. If a girl becomes pregnant after initiating the vaccination series, the remainder of the 2-dose regime should be delayed until after completion of the pregnancy. In the event that the HPV vaccine is inadvertently administered to a girl who is pregnant, no intervention is necessary. No health problems in mother or child have been observed to date after accidental HPV vaccination during pregnancy Pic 3: Girls with severe febrile illness should not be vaccinated A minor infection such as a cold is not a contraindication
What should you do in this scenario? The girl is pregnant when she returns for second dose of HPV vaccine. In the event that a girl is pregnant after initiating the vaccination series, the remainder of the 2 dose regimen should be delayed until after completion of the pregnancy.
What should you do in this scenario? The girl is immunocompromised due to HIV/AIDS. HPV vaccination is safe and immunogenic and does not cause problems for HIV-infected persons who get the vaccine. HPV vaccine is not contraindicated in HIV-infected girls. However, the immune response and vaccine efficacy might be less than in persons who are immunocompetent. Vaccinate as usual. Therefore, HIV-infected girls should be given 3 doses – following a 0, 1, 6 month schedule
What should you do in this scenario? The girl came in to an immunization session for her second dose. Ten months have passed since she received the first dose. Give the second dose of HPV vaccine.
