Vaccination against influenza in seniors significantly reduces the risk of death. However, only 20% of them are protected


Czech Republic – More than 2 million people over 65 live in the Czech Republic.1 Everyone is entitled to free flu vaccination. The seniors belong to the so-called risky population because they are at risk of serious illness and other complications.2 People over the age of 65 are up to 60 times more likely to die and generally constitute the category most influenced by the flu.3a Vaccination is the only prevention that effectively protects the flu, mitigates the disease and can prevent fatal consequences. Nevertheless, only about 20% of older people are 65+ in the Czech Republic.4a

The problem is diabetes, which affects up to 20% of the elderly. its
The danger in older years lies in the fact that it can manifest itself
atypical and non-specific symptoms.7 Age is a risk factor
even in the case of pneumonia (pneumonia), whose presence through influence
decreasing immune response increases especially after 65 years.5b

Influenza in Chronic Nurses – Double Pistol

"Cooling of flu in chronically ill patients is double. Individual chronic
Diseases increase the risk of flu, flu also contributes significantly

two strains B) and provide even greater protection.

Health and medicine

The benefits of vaccination are confirmed by a number of scientific studies. It follows that in addition to direct effect, vaccination also plays a secondary role in the prevention of complications, hospitalizations and deaths. In the case of seniors, the elderly living outside the health centers contribute to a 30-70% reduction in hospital stays due to pneumonia and flu. For seniors living in care facilities, vaccination reaches 50-60% of the effectiveness in preventing hospitalization or pneumonia and up to 80% of the effect on the prevention of deaths.8 In practice, this means that the vaccinated senior may get sick, but the disease progression is mild and unexplained, significantly less exposed to life.
