By San José, Costa Rica — San José, Costa Rica – In a decisive public health move, the Costa Rican Social Security Fund (CCSS) is preparing to launch a yellow fever vaccination campaign for travelers as early as December. The initiative follows the country’s first confirmed case of the disease, an imported infection in a 29-year-old American woman who had traveled from the Peruvian Amazon.
Health officials have moved quickly to reassure the public, with the Ministry of Health stating that the probability of a local outbreak remains very low. However, the incident has accelerated plans to bolster the nation’s preventative measures for citizens traveling to high-risk regions. The public vaccination program will begin with an initial lot of 15,000 doses donated by the Ministry of Health.
The mandatory yellow fever vaccination for travelers from specific countries raises important legal questions regarding entry requirements, individual rights, and corporate responsibilities for international employees. To delve into these complexities, TicosLand.com consulted with Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the firm Bufete de Costa Rica.
Companies sending employees to at-risk zones must understand that the yellow fever vaccine is not just a recommendation; it’s a critical component of their legal duty of care. Neglecting this can lead to significant liability in cases of illness and may even violate international health and safety regulations, creating both legal and financial exposure for the business.

The legal framework highlighted here is a critical reminder that employee wellness and corporate liability are deeply intertwined. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for his invaluable perspective, which underscores that for companies operating internationally, proactive health measures are not just best practice—they are a fundamental legal and financial imperative.
Mónica Taylor, Executive President of the CCSS, confirmed that the institution is working diligently to have the service operational within the next month. She outlined a cautious but optimistic timeline for the rollout.
We would give a date for December. If it’s sooner, that’s better news, but I don’t dare to tell you that we will be ready by then.
Mónica Taylor, Executive President of the CCSS
Taylor also explained that the CCSS is simultaneously initiating its own procurement process to secure a larger, independent supply of the vaccine. This institutional purchase is a more complex procedure expected to take approximately three months. “The internal protocol and contact with PAHO have already been activated; we will hold meetings with the team to start as soon as possible,” she added, referencing the Pan American Health Organization.
Acting Minister of Health, Mariela Marín, announced that the National Commission for Vaccination and Epidemiology (CNVE) has officially included the yellow fever vaccine in its special scheme for travelers. This designation formalizes its recommendation and availability for those journeying to areas where the virus is endemic. The vaccine will be available through the CCSS for insured individuals, while others will need to seek vaccination through private clinics and pharmacies.
This vaccine will be administered to people traveling to at-risk areas and must be given 10 days before departure.

Currently, Costa Rica only mandates proof of yellow fever vaccination for travelers arriving from or heading to Colombia, a policy reinforced by the presence of both jungle and urban transmission cycles in that country. For other at-risk destinations such as Brazil, Peru, Ecuador, and Venezuela, the requirement has been postponed until February 28, 2026. This extension is largely due to a global supply shortage, as manufacturers prioritize countries experiencing active outbreaks.
While the public sector prepares its rollout, the private market already has doses available. Massimo Manzi, Executive Director of the Costa Rican Chamber of Health, reported that a survey of major pharmacies confirmed an existing stock of approximately 5,000 doses. “They are being sold at an approximate price of ¢70,000, with some variation from pharmacy to pharmacy,” Manzi stated. He also revealed that an additional import of 25,000 doses is anticipated for the first week of November, bolstering the private supply significantly.
Yellow fever is an acute viral disease transmitted by infected mosquitoes in tropical regions of Africa and South America. According to the Pan American Health Organization, symptoms include high fever, headache, muscle pain, and jaundice—a yellowing of the skin and eyes that gives the disease its name. A single dose of the vaccine provides lifelong protection and is recommended at least 10 days before traveling to an endemic zone.
