  22. 22. ACIP & AAP - 2011 Consider giving HPV4 to MALES age 9 through 26yrs to reduce their likelihood of acquiring genital warts.
  23. 23. IAP & FOGSI • HPV vaccine should be given to females from 9-45 years of age for prevention of cervical cancer.
  24. 24. GARDASIL® indication as per DCGI GARDASIL® is indicated in females aged 9 through 45 years "for prevention of cervical, vulvar, and vaginal cancer, precancerous or dysplastic lesions, genital warts, and infections caused by Human Papillomavirus (HPV) Types 6, 11, 16 and 18 (which are included in the vaccine).“
  25. 25. Clinical Trials Overview
  26. 26. GARDASIL Conclusions (FUTURE Trials) • GARDASIL yields the greatest benefit in adolescent girls prior to exposure to HPV • However, women of all ages remain at risk for HPV- related infection and disease • Data demonstrate that women aged 24-45 benefit from vaccination with GARDASIL – GARDASIL showed a high level of efficacy against disease caused by HPV Types 6/11/16/18 in this age group – GARDASIL significantly reduced abnormal Pap tests caused by vaccine HPV types – Vaccination with GARDASIL may significantly impact the burden of cervical cancer and HPV-related diseases among women aged 24-45
  27. 27. A registry based long term follow up (LTFU) study of the Quadrivalent HPV vaccine in 4 Nordic Countries

  29. 29. GARDASIL® : Nordic Cancer Registry Extension Evaluation of Long-Term Efficacy of Vaccination • Nordic European countries have organized mass screening programs. – Compulsory reporting of Paps, biopsies, CIN/cancer • By enrolling phase III studies in the region, we can evaluate: – Duration of effectiveness – Data for use in assessing interaction of vaccination with cervical screening programs – Long-term safety Denmark Norway Iceland Sweden

  31. 31. Conclusions – Nordic Study • Extensive monitoring of Gardasil is ongoing in Nordic countries as an extension of FUTURE 2 study. • No breakthrough cases of HPV 16/18 related CIN 2 or worse. • GARDASIL shows a trend of continued protection in women who were vaccinated up to 7 years previously. • GARDASIL continues to be generally safe and well tolerated up to 6 years following vaccination.
  32. 32. • Cervical cancer causes significant morbidity/ mortality • HPV vaccine to be offered to all appropriate females who can afford the vaccine • Vaccine should be given prior to sexual debut www.fogsi.org/hpv vaccine
  33. 33. • Age for initiation of vaccination is 10- 12 years. – Catch up vaccination is permitted up to the age of 45 years for both vaccine • 3 doses at 0, 2 and 6 months with quadrivalent vaccine • 3 doses 0, 1 and 6 months with bivalent vaccine www.fogsi.org/hpv vaccine
  34. 34. •At present there is no data to support use of boosters
  35. 35. • Sexually active women and women with previous abnormal cervical cytology can receive the HPV vaccine • Benefits may be limited to the protection against infection of HPV genotypes with which they have not been infected
  36. 36. • The vaccine can be given to patients with previous CIN, but the benefits may be limited to the protection against infection of HPV genotypes (and related CIN) with which they have not been infected • The HPV vaccine is not therapeutic. It does not treat existing HPV infection or cervical intraepithelial neoplasia (cervical pre-cancers) FOGSI Recommendations: Women With Previous CIN
  37. 37. –Not recommended for use in pregnancy –If patient becomes pregnant - Delay remaining doses till delivery –If vaccinated during pregnancy - No intervention (MTP) needed –Lactating women can receive the HPV vaccine (Gardasil) and still continue breastfeeding as it is a vaccine without live viral DNA FOGSI Recommendations: Pregnancy & Lactation
  38. 38. • Vaccinated women should be screened as per the standard guideline • Screen positive women may be vaccinated after counseling • Screening/ HPV test is NOT REQUIRED prior to vaccination FOGSI Recommendations: Vaccination & SCREENING
  39. 39. The WHO’s (World Health Organisation) Global advisory committee on vaccine safety (GACVS), the Vaccine adverse event reporting system (VAERS), the Food & drug administration (FDA) and the Centers for disease control & prevention (CDC) have all confirmed and declared that the HPV vaccination is safe & effective providing protection against HPV 16, 18, 6 & 11 associated cervical, vulvar & vaginal cancer, genital warts and other HPV-related genital diseases in females. Vaccination against HPV is safe & effective
  40. 40. • VACCINATION: One of greatest public health achievements in the world • With the exception of clean drinking water, vaccines are the most effective intervention in reducing and preventing the return of infectious disease1 • 26 diseases are now vaccine preventable2 Let’s add Cervical Cancer to this list! Value of Vaccination Today
  41. 41. Summary  HPV is a necessary cause of cervical cancer – 99.7%  Induction of neutralizing antibodies by vaccination is critical for protection  HPV 16 & 18 cause ~75%* of cervical cancer cases while HPV 6 & 11 cause ~90% genital warts  27% of the world burden of Cervical Cancer is seen in India.  Every 7 minutes a woman dies in India due to cervical cancer  Cervical Cancer is usually diagnosed in late stages in India.  Cervical cancer screening is recommended in women >30yrs  Vaccination between 9-45yrs can be an effective strategy to help reduce this huge disease burden.
