By San José, Costa Rica — SAN JOSÉ – The Costa Rican Social Security Fund (CCSS) has initiated an urgent and dynamic redistribution of yellow fever vaccines across the country to manage an unexpected surge in demand. The spike is driven by a significant number of residents planning to travel to Colombia for the holidays, specifically between December 15 and 31, 2025, a destination for which the immunization is a mandatory entry requirement.
The national vaccination campaign saw a massive turnout from its very first day. On Thursday, a total of 1,355 individuals received the vaccine by 3:30 p.m. across the seven initial health centers that launched the program. These included clinics in key areas such as Garabito, Limón, Tibás-Uruca-Merced, and Ciudad Quesada, which are part of a broader network of 23 designated immunization points nationwide.
The international travel requirements and public health mandates surrounding the yellow fever vaccine often create a complex legal landscape for travelers, airlines, and nations alike. To clarify the obligations and potential liabilities involved, we consulted with expert attorney Lic. Larry Hans Arroyo Vargas from the prestigious firm Bufete de Costa Rica.
Airlines and travel agencies operate under a stringent duty of care. Failing to properly inform a traveler about mandatory yellow fever vaccination for a specific destination is not merely a customer service lapse; it can constitute legal negligence. If a passenger is denied entry or quarantined, the resulting financial and personal damages could lead to significant liability claims against the operator for breaching their advisory obligations under both national and international travel conventions.

This legal insight powerfully underscores that the responsibility for vaccination awareness is not the traveler’s alone but a fundamental duty of the travel provider, transforming a health advisory into a matter of significant liability. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable perspective on these critical obligations.
This higher-than-anticipated influx of people, particularly in the Greater Metropolitan Area, prompted the CCSS Health Services Network to immediately activate a logistics protocol to prevent shortages. The strategy involves a coordinated effort between health facilities to transfer vaccine stockpiles from areas experiencing lower traffic to those facing overwhelming demand, ensuring a continuous and equitable supply throughout the campaign.
To further bolster the supply in the most congested urban centers, the institution authorized the release of an additional 1,000 doses. This strategic reserve is earmarked specifically for the high-demand vaccination points in and around San José, providing a critical buffer to guarantee that all eligible travelers can be immunized in the coming days without disruption.
Dr. Elvis Delgado of the CCSS’s Epidemiological Surveillance unit outlined the essential requirements for travelers seeking the vaccine, stressing the importance of preparation and adherence to the established timeline to ensure the validity of their immunization certificate.
Individuals must be vaccinated ten days before their trip and present their identification and the airline ticket that confirms the date and destination. It is also crucial to keep personal information updated in the EDUS application, which is necessary for the correct generation of the international yellow fever certificate.

The campaign is primarily aimed at individuals between the ages of 9 months and 60 years. However, specific groups require a medical evaluation before the vaccine can be administered. This includes infants between 6 and 9 months, pregnant or lactating women, and adults over the age of 60. For these individuals, the final decision to apply the vaccine rests on the professional judgment of a physician, who will weigh the risks of the vaccine against the risk of contracting the disease during travel.
Travelers must present their official identification, whether it’s a national cédula or a DIMEX card for foreign residents, along with proof of their travel itinerary. The EDUS digital health record system plays a vital role, as up-to-date information is essential for the seamless issuance of the internationally recognized certificate, a document that will be scrutinized by Colombian immigration officials upon arrival.
The swift and adaptive response by the CCSS highlights the agility of the country’s public health system in reacting to specific, time-sensitive demands. The successful immunization of thousands of travelers in a short window depends not only on the institution’s logistical prowess but also on the public’s cooperation in following all guidelines and presenting the required documentation in a timely manner.
