Which of the following is NOT a strategy for preventing the transmission of hepatitis C in healthcare workers?

The option related to vaccination against HCV is not a strategy for preventing the transmission of hepatitis C in healthcare workers because, as of the current understanding, there is no available vaccine for hepatitis C. While the other strategies listed are effective measures in reducing the risk of transmission of the virus, vaccination is not applicable because immunization options do not exist for this specific virus.

Proper disposal of sharps is essential for minimizing the risk of exposure to bloodborne pathogens, including hepatitis C. Using standard precautions, which involves practices like hand hygiene and the use of personal protective equipment, also plays a critical role in infection control. Isolating patients with hepatitis C may be considered in specific healthcare settings to prevent transmission, particularly in situations where additional measures are required. Thus, the choice concerning vaccination stands out as the only method not available for preventing hepatitis C transmission among healthcare workers.
