Nepalese government has launched a vaccination campaign in its Chitwan and Kaski districts to prevent Human Papillomavirus infections (HPVs) among women. HPV, a sexually transmitted virus, causes uterine cancer and has been found among 70 per cent of the total female cancer patients in Nepal. Being the first initiative of its kind, around 30,000 vials of the vaccine will be administered to 14,500 girls twice a year. The vaccine is said to be effective if administered to girls before reaching puberty. The government is going to expand the drive to 75 districts.
