Explanation

Option B is not correct (and the right answer): Hepatitis B DOES have a highly safe, effective preventive vaccine (which is part of the Universal Immunization Programme), whereas Hepatitis C does NOT have an approved vaccine (though curative direct-acting antivirals exist). Statement B presents this inversely.

– Option A is correct: Both Hepatitis B and HIV are transmitted parenterally through infected blood, bodily fluids, unsterilized needles, and mother-to-child transmission during delivery.
– Option C is correct: According to WHO data, several hundred million people live with chronic viral Hepatitis B and C globally, exceeding global HIV prevalence.
– Option D is correct: Chronic hepatitis infections can remain asymptomatic for decades before progressing to cirrhosis or hepatocellular carcinoma.

Hence, the incorrect statement is Option B.
