How often should people receive the brucellosis vaccine?

Generally, there is no uniform standard for the interval between Brucellosis vaccinations in humans. The schedule mainly depends on the population group and the type of vaccine used. Routine vaccination is not required for the general population, while high-risk groups should receive regular booster doses according to established guidelines. A detailed analysis is as follows:

Brucellosis vaccines are primarily intended for high-risk populations such as those involved in animal husbandry, livestock breeding, slaughter, and processing. After initial immunization with commonly used human brucellosis vaccines, a booster dose is typically recommended every 2–3 years to maintain effective antibody levels. Immunization schedules may vary slightly depending on the specific vaccine; for some vaccines, the interval should be adjusted based on antibody testing results to ensure optimal protection. Since the general population has minimal risk of exposure to Brucella bacteria, vaccination is unnecessary and thus no fixed vaccination interval applies. Before vaccination, individuals in high-risk groups should confirm the absence of contraindications and monitor for mild local reactions such as redness or swelling after vaccination, providing basic care as needed.

In daily life, personal protective measures should be taken. Wear gloves and masks when handling livestock or related products to reduce infection risk, and follow professional guidance to complete booster vaccinations regularly.
