Yellow Fever Vaccine Side Effects
Yellow fever is an acute viral disease caused by yellow fever virus and transmitted through an infected mosquito bite. The disease doesn’t spread through direct contact, but once infected, hospitalization is required. It is prevalent in Africa and South America and is characterized by features like fever and flu-like symptoms, bleeding from multiple sites, Jaundice (yellowish discoloration), multi-organ failure involving kidneys, liver or respiratory system, and even death in about 20%-50% of critical cases.
Yellow Fever Vaccine Side Effects
YF-Vax or yellow fever vaccine is an effective preventive measure taken to prevent the development of the disease in children and adults. For the vaccine to work, children of about 9 months will be exposed to small amounts of the virus, so that the body develops immunity against it. Much like all the other vaccines, this vaccine doesn’t in any way treat the disease, it only prevents it. In case one is travelling to an area where yellow fever is endemic, it is a must to get vaccinated 10 days prior to arrival on the location. Although effective in preventing yellow fever, YF-Vax has its own side effects. You should be well-informed of these side effects in case medical attention is required.
