The yellow fever vaccination is mandatory only if you are entering Suriname from a country where yellow fever is present. This disease is found in parts of Africa and South America, including Suriname itself. If you are traveling from the Netherlands to Suriname without passing through a yellow fever-endemic country, the vaccination is not required but is recommended.
