Nationwide HPV vaccination campaign
One line
The Prime Minister launched a nationwide campaign for human papillomavirus vaccination as part of a cervical cancer prevention effort.
Summary
Persistent infection with high-risk types of human papillomavirus (HPV) is a major cause of cervical cancer. Vaccination works best as prevention before exposure, while screening, diagnosis, treatment, and follow-up remain essential for women who are already at risk.
The launch is a programme milestone. It does not remove the need for informed consent, safe delivery, cold-chain management, and equitable access.
PYQ pattern
UPSC health questions often test the difference between vaccination, screening, treatment, and vector control. Use the official UPSC archive and revise how public-health interventions work across the prevention spectrum.
Core notes
- HPV is a group of viruses transmitted mainly through intimate contact. Many infections clear, but persistent high-risk infection can cause cancer.
- Vaccination and screening are complementary. Neither replaces the other.
- Public campaigns need age-appropriate counselling, reliable safety communication, and systems to track doses and adverse events.
- Cervical cancer prevention also depends on access to primary care, pathology, referral, and treatment.
Prelims lens
- HPV is a virus, not a bacterium.
- HPV vaccination is preventive. It is not a treatment that clears every existing infection.
- Cervical screening remains relevant even where vaccination coverage is high.
MCQ 1
Consider the following statements:
- Persistent infection with some high-risk HPV types can cause cervical cancer.
- HPV vaccination makes cervical screening unnecessary for everyone.
- A. 1 only
- B. 2 only
- C. Both 1 and 2
- D. Neither 1 nor 2
Reveal answerHide answer
A
High-risk HPV infection is a major cause of cervical cancer. Vaccination does not remove the need for screening and follow-up.
MCQ 2
HPV vaccination is best classified as:
- A. primary prevention
- B. a curative cancer surgery
- C. a mosquito-control measure
- D. a food-subsidy instrument
Reveal answerHide answer
A
Vaccination reduces the risk of infection before disease develops. Screening and treatment address later stages of the prevention pathway.
Mains
Question, 10 marks, 150 words: A cervical cancer strategy must combine vaccination with screening and treatment. Explain why a single intervention is insufficient.
Approach:
- Define HPV and the prevention pathway.
- Explain vaccination, screening, early diagnosis, referral, and treatment.
- Discuss hesitancy, access, privacy, cold chain, and rural health gaps.
- Suggest trusted counselling, primary-care integration, registries, and affordable follow-up.
