Health officials reported that 93 percent of the people who died from influenza last year were not vaccinated, despite the fact that because all were members of high-risk groups, they were eligible to receive the vaccination for free.
Only 30 percent of the health care workers at the Costa Rican hospital with the largest concentration of deaths linked to H1N1 this season were vaccinated.
This year the Caja will use the vaccine produced for the southern hemisphere, rather than the one produced for the northern hemisphere. Authorities hope the change will protect more Costa Ricans against getting the flu.
