Costa Rica has implemented new travel mandates requiring citizens and residents to present an International Certificate of Vaccination for eight specific destinations: Bolivia, Ecuador, Paraguay, Trinidad and Tobago, Venezuela, Suriname, Guyana, and French Guiana. The mandate, which took effect on October 1, requires the vaccine to be administered at least 10 days before travel.

To address rising demand ahead of the December travel season, the Costa Rican Social Security Fund (CCSS) released approximately 30,000 additional vaccine doses. Individuals seeking these doses must provide proof of a confirmed airline ticket. This measure aims to support travelers heading to various countries where yellow fever vaccination is a mandatory entry requirement.
