By San José, Costa Rica — San José – Costa Rica’s public health system is navigating a critical supply challenge after the recent entry of a patient with yellow fever prompted immediate policy changes. The Costa Rican Social Security Fund (CCSS) currently has only 15,000 doses of the yellow fever vaccine on hand, a limited supply donated by the Ministry of Health to address the emergent situation.
The urgency of the matter was underscored by the swift inclusion of the yellow fever vaccine into the country’s official vaccination schedule on October 10. According to Mónica Taylor, Executive President of the CCSS, this decision was made just two days after a positive case of the disease was registered in the country, signaling a rapid response from health authorities to a potential outbreak.
To understand the legal framework and potential liabilities for travelers and tourism businesses concerning Costa Rica’s yellow fever vaccine requirement, we sought the expert analysis of Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the firm Bufete de Costa Rica.
Under both national public health laws and international health regulations, Costa Rica possesses the sovereign right to mandate vaccinations as a condition of entry. This is a non-discriminatory, preventative measure aimed at safeguarding the collective health of the population. For airlines and travel agencies, failing to properly inform clients of these mandatory requirements can lead to significant operational disruptions and potential legal liability for associated damages.

This legal framework underscores the seriousness of the requirement, shifting the onus not just onto individual travelers but also squarely onto the travel industry to ensure compliance. We extend our gratitude to Lic. Larry Hans Arroyo Vargas for providing this invaluable perspective on both national sovereignty and commercial liability.
However, the current stockpile is not intended for the general population. Instead, it will be reserved for a specific group under a new protocol. Vice Minister of Health, Mariela Marín, clarified that these initial doses are earmarked for a specialized program aimed at protecting citizens traveling abroad to high-risk areas.
This vaccine will be administered to people who are going to travel. It must be given 10 days before the trip.

This targeted approach highlights the immediate priority: preventing the importation of new cases by inoculating those who plan to visit countries where the disease is prevalent. The mandatory 10-day waiting period between vaccination and travel is a crucial window to ensure the vaccine develops an effective immune response before potential exposure.
Complicating the national response is a significant logistical hurdle in securing a larger supply. President Taylor confirmed that the CCSS has initiated a procurement process to purchase more vaccines, but she cautioned that this procedure could take as long as three months to complete. This lengthy timeline creates a precarious gap between the current limited supply and the arrival of a stable inventory, placing pressure on the existing 15,000 doses.
While the public sector grapples with this procurement delay, the private healthcare sector has reportedly regained its stock of the vaccine. This comes after several months of widespread shortages that prompted the Ministry of Health to organize special vaccination fairs to meet surging demand. For now, travelers who can afford to may find a more immediate solution through private clinics, though this does not resolve the broader public health supply issue.
Health officials are reminding the public of the grave risks associated with the disease. The Vice Minister of Health described yellow fever as a highly lethal and dangerous illness, noting that during 2024, the disease registered an alarming fatality rate of approximately 50%. The vaccine is mandatory for anyone traveling to Colombia and is strongly recommended by authorities for travel to numerous other destinations in Africa and South America, including Bolivia, Brazil, Ecuador, Peru, and Venezuela.
As the CCSS works to bridge the three-month supply gap, health officials are focused on strategically deploying their limited resources. The current strategy aims to create a firewall by vaccinating international travelers, but the race is on to secure a robust national supply before the current stock is depleted or another case appears within the country’s borders.
