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 has the right to vaccinate against free flu. Seniors belong to the so-called risky group of the population because they are at risk of serious illness and other complications.2 People aged over 65 are up to 60 times more likely to die and generally form the category most affected by influenza.3a Vaccination is the only prevention that effectively protects the flu, attenuates disease progression and can prevent fatal consequences. However, only about 20% of the elderly are in the Czech Republic over 65 years of age.4a

Total 75-90% of people
over 65 for the consequences of the death of the flu.3b, 5a"The cause of death is not just the illness itself, but other health problems
the complications the flu can cause. Age is associated
– physiological changes – in addition to metabolism, mass or muscle function;
The morphology of the tissues also changes the immune system, which in turn leads to a reduction
resistance to various infections, including flu,
he says MD. Zdeněk Jágrvá, director
Antiepidemic Hygiene Center of Prague Capital.

Danger of disease
influenza is increasing in the elderly in connection with chronic diseases, which
the elderly are often found. Experts say one or more diseases at the same time
suffer from over 90% of people over the age of 70. Statistics show up to 3/4 people
in the 65+ age group, face heart disease and vessels, half grew
blood pressure, 37% ischemic heart disease.6 Another frequent
the problem is diabetes, affecting up to 20% of seniors. They
the danger of past years is that it can be manifested
atypical and nonspecific.7 Age is a risk factor
also in connection with pneumonia (pneumonia), whose presence through influence
the decrease in immune defense increases especially after 65 years.5b

Influenza in patients with chronic diseases – double weapon

Chillingness of influenza in chronic patients is double. Individual Chronicle
diseases increase the risk of influenza, influenza also contributes significantly to
aggravation of the current state of health. However, it is considerably underestimated, not only
among the elderly population, but in the Czech Republic in general, "
warn MD. Zdeněk Jágrvá. Czech Republic
is only at the level of 5-6%3c, between seniors, then about 20%4b.
Both the World Health Organization and the European institutions recommend vaccination
seniors at a level of at least 75%.3d Seniors are in Czech
The Republic as a risk group is entitled to vaccinate against free flu. completely
the four-valent Vaxigrip Tetra vaccine this year is also covered
of the last season on the Czech market. Compared to the previous three-sided wall
Vaccines act against four flu viruses (two strains A and B)
two strains B) and provides greater protection.


The benefits of vaccination are confirmed by a series of scientific studies. It follows that, in addition to the direct effect, vaccination also plays a secondary role in preventing complications, hospitalizations and deaths. For the elderly, elderly people living outside care centers contribute to a 30-70% reduction in hospitalizations due to pneumonia and influenza. For elderly people living in care centers, vaccination reaches 50-60% of the prevention of hospitalization or pneumonia and up to 80% of the efficacy in preventing death.8 In practice, this means that the vaccinated senior may be ill, but the course of the disease is mild and, innocently, is significantly less vulnerable to life.
