More about Yellow fever
Yellow fever is a tropical virus found in areas such as South America, Central America, Africa, and the Caribbean.
It affects the liver which causes symptoms such as yellowing of the eyes, skin and fevers. Hence the name “Yellow Fever”.
It is spread from person to person by mosquitoes.
Vaccination is highly recommended, along with other precautions such as mosquito nets and insect repellent. It is also advisable not to travel to areas which have outbreaks.
The vaccination takes ten days after administration before it becomes effective. This means you must have your vaccination 10 days before travel.
Leaving your vaccine too late could result in not being allowed to enter the country you are destined for. It also means you will not be fully covered for Yellow fever.
The Yellow fever vaccine lasts up to ten years, however it is always best to seek advice before travelling even if you feel you are covered against any diseases active in the country you are visiting.
The Yellow fever vaccine is a live vaccine and can not be given to anyone that has already had a live vaccine within a one month period.
Examples of other live vaccines are measles, mumps, rubella and the varicella vaccine.
If you are concerned about any of these vaccines or need advice on when to obtain the Yellow fever vaccine then please get in touch.
