yellow fever vaccine

The yellow fever vaccine is a shot that protects against a viral disease transmitted by infected mosquitoes, primarily in parts of Africa and South America. The vaccine stimulates your immune system to recognize and fight the yellow fever virus if exposed, significantly reducing the risk of illness. It is usually given as a single dose and provides long-lasting protection, often for life. The vaccine is important for travelers to endemic areas and for those at risk of exposure. It is safe and effective, with few side effects, but should be administered by healthcare professionals, especially for individuals with certain health conditions.
