HPV Vaccination Drive: A Major Step in India's Fight Against Cervical Cancer
Why in News?
The Union government is set to launch a nationwide single-dose HPV vaccination drive aimed at 14-year-old girls to combat cervical cancer in India. Cervical cancer ranks as the second most prevalent cancer among Indian women, with nearly 90% of cases linked to persistent human papillomavirus (HPV) infections. Since many HPV-related cancers are preventable through vaccination, a widespread immunization effort can significantly alleviate the disease burden. In addition to cervical cancer, HPV vaccination can also decrease the occurrence of anal, penile, vaginal, vulvar, and throat cancers, making this campaign a critical public health initiative to reduce cancer-related morbidity and mortality across the country.
Key Takeaways
- The HPV vaccination drive targets 14-year-old girls across India.
- Eligible individuals must book appointments via the U-Win digital platform.
- Gardasil will be the vaccine used for this campaign.
- India accounts for nearly 20% of the global cervical cancer burden.
Additional Details
- HPV and Cancer Risk: There are over 14 cancer-causing HPV strains, with types 16 and 18 alone responsible for about 70% of cervical cancer cases worldwide. Vaccines are designed to protect against these high-risk strains.
- Vaccine Being Used: The government will utilize Gardasil, produced by MSD Pharmaceuticals, known for its proven efficacy and safety.
- Indigenous Vaccine Status: India's own vaccine, Cervavac, is not yet in use as it awaits WHO approval and is still under evaluation by the ICMR for effectiveness as a single-dose vaccine. A potential shift to Cervavac is anticipated in about two years.
- Supply Plan: The GAVI Vaccine Alliance will supply 2.6 crore doses for the campaign, with one crore doses already received. Remaining doses will be delivered throughout the year and the next.
- Public Health Gains: The HPV vaccine's effectiveness in reducing cervical cancer incidence has been well-documented. Vaccinating girls can also lead to indirect protection for boys and enhance community immunity.
The upcoming nationwide campaign marks India's first large-scale HPV vaccination initiative, although some states have previously launched targeted programs with notable success. For example, Sikkim achieved over 95% coverage in its 2018 vaccination drive, while Punjab and Delhi have also undertaken efforts with varying levels of success. This ambitious campaign is expected to significantly impact public health by reducing cervical cancer rates and improving healthcare resource allocation.

Why in News?
Zimbabwe has initiated the rollout of Lenacapavir, a long-acting injectable drug designed for HIV prevention. This significant development marks an important step in expanding the options for pre-exposure prophylaxis (PrEP) across Africa, with Zimbabwe being one of the first countries on the continent to introduce this innovative treatment.
Key Takeaways
- Lenacapavir is administered as an injectable drug for HIV prevention, given twice a year.
- This long-acting treatment improves adherence compared to daily oral pills.
- The drug functions by inhibiting the HIV capsid, effectively preventing viral replication.
- The rollout specifically targets high-risk groups, including adolescent girls and young women.
- This initiative aims to reduce the incidence of new HIV infections in a region significantly affected by HIV/AIDS.
- It represents progress towards achieving global goals for HIV prevention and epidemic control.
Additional Details
- HIV (Human Immunodeficiency Virus): HIV is a retrovirus that attacks the body's immune system, specifically targeting CD4 (T-helper) cells. It weakens the immune response, making individuals susceptible to opportunistic infections and certain types of cancer.
- Progression to AIDS: If HIV is not treated, it can advance to AIDS (Acquired Immunodeficiency Syndrome), a critical stage of the infection.
- Transmission: The virus spreads through unprotected sexual contact, transfusion of infected blood, sharing needles, and from mother to child during pregnancy, childbirth, or breastfeeding.
- Treatment: While there is currently no cure for HIV, antiretroviral therapy (ART) enables people living with HIV to lead long and healthy lives.
- Preventive Measures: Effective strategies include safe sex practices, blood screening, needle safety, PrEP, and ART for viral suppression.
The introduction of Lenacapavir in Zimbabwe symbolizes a crucial advancement in the fight against HIV/AIDS, providing hope to vulnerable populations and contributing to the global effort to control the epidemic.
