The Future of Yellow Fever Vaccination: Trends and Challenges
Yellow Fever: An Ongoing Threat
Yellow fever, a grave mosquito-borne disease, remains a pressing concern. The virus, transmitted by Aedes aegypti mosquitoes, doesn’t respect borders or timelines. As highlighted by Mary Munive, the vice president and minister of health, the disease is actively spreading in regions like Brazil, Peru, and Colombia. The recent surge in cases—61 recorded throughout 2024 and 16 in January 2025 alone—holders alarm bells, particularly given the virus’s 50% mortality rate.
Highlighting the urgency of the situation, Munive emphasized that the mosquito does not understand "stationery." It doesn’t pause for vaccine extensions or wait for policy changes. This dynamic highlights the need for continuous vigilance and preparedness in affected regions.
The Vaccination Challenge
Costa Rica, like many other countries, faces significant obstacles in maintaining an adequate supply of the yellow fever vaccine. Due to distribution issues from one of the two main producers, the available vaccine stock must be diverted to areas where outbreaks are already active. This shortage has led to the suspension of mass immunization campaigns, which were previously held in December and January.
Mandatory Vaccination for Travelers
Despite the shortfall in vaccine supply, travel restrictions will be enforced. Starting soon, all travelers—including Costa Ricans—visiting Colombia, Brazil, or Peru, must present an immunization certificate against yellow fever. These countries are popular tourist destinations, especially during Holy Week and mid-year vacations. This measure aims to mitigate the spread of the disease across borders.
Key Destinations and Vaccination Requirements
Preventive Measures and Public Awareness
The Ministry of Health, under Munive’s direction, has been relentlessly communicating the risks and necessities of yellow fever prevention. Extensions to vaccine mandatory dates were previously implemented to alleviate public inconvenience and ensure compliance. Munive emphasizes the importance of sustained public engagement and efforts in maintaining vaccination status, vital for protecting against this fatal disease.
