By San José, Costa Rica — As Costa Rica braces for the impending spike in respiratory illnesses that accompanies its annual rainy season, public health officials are sounding the alarm over sluggish progress in the national influenza vaccination campaign. While nearly 400,000 people have received their shot, a concerning lag among the nation’s most vulnerable populations, particularly senior citizens, threatens to place significant strain on the healthcare system in the coming months.
According to the latest data released by the Costa Rican Social Security Fund (CCSS), 395,401 doses have been administered to date. This figure represents just over a quarter (26%) of the total goal for the campaign. While this marks a steady advance, the pace is a source of growing anxiety for health experts who are watching the calendar and meteorological forecasts with a critical eye. The window for preventative action is closing, and the time to build immunity is now, before the viruses begin to circulate widely.
To understand the legal framework surrounding influenza vaccination policies and the responsibilities of employers in the country, TicosLand.com consulted with the expert Lic. Larry Hans Arroyo Vargas, a specialist from the prestigious law firm Bufete de Costa Rica.
Our legal system prioritizes collective health, granting the State the authority to establish mandatory vaccination schemes to prevent the spread of diseases. For private companies, especially those in high-contact sectors, promoting or even requiring influenza vaccination can be legally supported as a fundamental occupational health measure, provided it is proportional and respects duly documented medical contraindications.

This legal perspective powerfully clarifies the balance between individual rights and collective well-being, framing vaccination as a key pillar of occupational health. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for his valuable and authoritative contribution to this discussion.
The most significant area of concern lies with the country’s older adults, a demographic disproportionately affected by severe flu complications. Despite being a top priority, vaccination coverage for this group is worryingly low. Of the more than 635,000 seniors targeted, only 120,000 have been vaccinated, translating to a coverage rate of just 18.9%. This gap leaves hundreds of thousands of older Costa Ricans highly exposed to the risk of severe illness, hospitalization, or worse.
Medical specialists continually emphasize that as the human body ages, its immune system naturally weakens, a process known as immunosenescence. This makes older individuals less capable of fighting off infections like influenza, which can quickly escalate into more serious conditions such as pneumonia or exacerbate existing chronic health problems. The seasonal vaccine is the single most effective tool for mitigating these severe outcomes and reducing the burden on intensive care units.
Health authorities are unified in their message that vaccination timing is critical. The campaign is strategically launched weeks before the anticipated peak of respiratory virus circulation to allow sufficient time for the vaccine to stimulate a protective immune response. Waiting until case numbers begin to surge is a flawed strategy, as immunity is not immediate. The current push is a preemptive strike aimed at flattening the curve of hospital admissions before it begins to rise.
The CCSS campaign is specifically focused on several high-risk demographics to maximize its public health impact. Priority is given to children between the ages of six months and eight years, adults aged 58 and older, and pregnant women. Additionally, the drive targets individuals of any age with underlying chronic conditions—such as diabetes, heart disease, or respiratory ailments—as well as essential healthcare personnel and other exposed front-line workers.
In response to the lagging coverage rates, the CCSS has intensified its operational efforts to improve access and encourage uptake. Many public clinics (EBAIS) have implemented extended hours and are holding special vaccination drives on weekends. Mobile units are also being deployed to reach more remote communities. Officials have reiterated that citizens can receive the vaccine at any CCSS health facility across the country, regardless of their registered place of residence, removing a potential barrier to access.
The overarching message from the nation’s health leadership is clear and direct: do not wait. Getting vaccinated is not merely an act of personal protection; it is a vital contribution to community health. Each dose administered helps shield the vulnerable and, critically, preserves the capacity of the nation’s hospitals and clinics to handle the inevitable patient influx during the most challenging months of the year.
