Workers exposed to blood or body fluids should be vaccinated with which vaccine?

Vaccination with the Hepatitis B vaccine is essential for workers who are exposed to blood or body fluids because Hepatitis B is a highly infectious virus that can be transmitted through contact with infected blood. Health care professionals, first responders, and others in similar fields are at significant risk of exposure to blood, making this vaccine a critical component of occupational health and safety protocols.

The Hepatitis B vaccine is effective in preventing the infection, which can lead to serious health complications, including chronic liver disease and liver cancer. Administering this vaccine is a standard precaution to protect individuals who might encounter potential bloodborne pathogens in their work environment.

The other vaccines listed, while important in different contexts, do not provide protection against the specific risks associated with exposure to blood or body fluids. For example, the flu vaccine protects against seasonal influenza, MMR relates to measles, mumps, and rubella, and the tetanus vaccine is primarily aimed at preventing tetanus infection through wound contamination. Thus, the Hepatitis B vaccine is the specific vaccine recommended for those at risk of exposure to blood and body fluids.
