The yellow fever vaccine is a live, attenuated vaccine that provides immunity against the disease. It's administered in one dose, and protection begins to take effect about 10-14 days after vaccination.

The vaccine works by triggering an immune response in your body, which produces antibodies that can neutralize the virus if you're exposed to it. The vaccine is highly effective, with a single dose providing lifelong immunity against yellow fever.

Who Should Get Vaccinated?

The World Health Organization (WHO) recommends that anyone traveling to areas where yellow fever is prevalent should get vaccinated at least 10 days before their trip. This includes:
  • Travelers visiting or working in Africa and South America, particularly during peak transmission seasons.
  • People living in areas where yellow fever is endemic or epidemic.
  • International travelers returning to countries with high levels of yellow fever transmission.

If you're traveling to an area where yellow fever is present but not endemic, it's still a good idea to get vaccinated. Consult your healthcare provider for guidance on whether the vaccine is recommended for your specific travel plans.
