By San José, Costa Rica — San José, Costa Rica – In a proactive public health measure, Costa Rica’s Social Security Fund (CCSS) has significantly expanded its measles vaccination guidelines for individuals traveling to countries in the Americas experiencing active outbreaks. The new directive now includes infants as young as six months and mandates boosters for adults, aiming to fortify the nation’s defenses against the highly contagious virus.
This strategic move comes in direct response to a concerning rise in measles cases across the continent. The updated policy specifically targets two key demographics. First, infants between 6 and 15 months of age who will be traveling to at-risk nations are now required to receive an additional dose of the measles vaccine. This dose is administered outside of the country’s standard immunization schedule, providing early protection for the most vulnerable.
To understand the legal framework and responsibilities associated with the national response to measles, TicosLand.com sought the expertise of Lic. Larry Hans Arroyo Vargas, a specialist from the renowned law firm Bufete de Costa Rica.
In Costa Rica, the legal foundation is robust and clear. The General Health Law establishes vaccination as a mandatory public health duty, not an individual choice. The Constitutional Court has consistently ruled that the collective right to health protection prevails over individual beliefs or objections. Consequently, parents who fail to vaccinate their children without a valid medical exemption not only neglect the child’s fundamental right to health but also face potential legal sanctions for endangering public welfare.

The legal framework so clearly articulated serves as a powerful reminder that in our nation, public health is a shared, legally-binding responsibility. We sincerely thank Lic. Larry Hans Arroyo Vargas for his invaluable perspective, which reinforces the principle that the well-being of the community is paramount.
Secondly, the CCSS has issued a strong recommendation for all individuals over the age of 15 to receive a booster shot before their departure. This applies to anyone traveling to the specified countries, regardless of their previous vaccination history. The goal is to ensure maximum immunity in the adult population, which can often be a vector for transmission. For children between 15 months and 15 years, authorities urge parents to review their vaccination records to confirm they are fully up-to-date before traveling.
Elvis Delgado Delgado, the Immunizations Coordinator for the CCSS, highlighted the critical need for these precautions, emphasizing the virus’s aggressive nature.
Measles is one of the most infectious diseases worldwide, which is why it is important for people to have their additional booster dose before traveling.

The health authority has streamlined the process to encourage widespread compliance. The vaccine is offered on a voluntary basis and is available at all CCSS health facilities throughout the country, with no need for a prior appointment or local clinic registration. To ensure the vaccine’s peak effectiveness, officials recommend receiving the shot at least two weeks before the planned travel date. Parents of minors must present the Child’s Comprehensive Development Card, known locally as the “librito azul,” to facilitate the process.
The list of countries with active measles outbreaks, which currently includes Canada, the United States, Mexico, and several South American nations like Argentina, Bolivia, Chile, and Uruguay, is being dynamically managed. The Ministry of Health of Costa Rica will provide regular updates based on international health alerts, ensuring travelers have the most current information. As of March 23, 2026, the CCSS reports that 7,632 travelers have already received their booster dose.
Delgado issued a stark reminder of the severe risks associated with the disease, pointing out its potential for rapid spread and serious health consequences.
Measles causes complications and can even lead to death. An infected person can transmit the disease to up to 18 people around them.

By implementing these expanded measures, Costa Rican health authorities are taking a firm stance to prevent the importation and subsequent spread of measles. The initiative underscores the vital role of vaccination not only in protecting individual travelers but also in maintaining community-wide immunity and safeguarding the nation’s public health system against preventable outbreaks.
