Influenza Facts - Seasonal influenza vaccine provides safe and effective protection
Seasonal influenza vaccine provides safe and effective protection against influenza. Extensive vaccination prevents the spread of influenza and complications, as well as protects risk groups.
Winter is the time of the year when influenza wave is to be expected at workplaces, schools and homes. Vaccination is the safest way to prevent seasonal influenza illness. Vaccination also prevents the spread of the disease. There are, however, many inaccurate or even false presumptions and statements about seasonal influenza and vaccination against it.
What is the difference between flu and seasonal influenza?
Typical symptoms of flu and influenza are quite similar, but in influenza the symptoms are usually more intense. Especially fever and muscle pain are more severe in influenza than in flu.
Similarly, the risk of bacteria caused complications such as pneumonia and ear infections are greater in influenza. The flu is caused by several viruses, and there is no vaccine against it.
What are the complications of influenza, where do they come from and what are their risks?
Typical complications of influenza include pneumonia and ear infections that may occur when the influenza virus has broken respiratory mucous membranes. From mucous membranes the bacteria can reach respiratory tract and bloodstream.
Elderly, small children, pregnant and people with multiple chronic illnesses it may lead to hospitalization and even to death.
How does seasonal influenza vaccine work?
Season influenza vaccine contains an inactivated part of the influenza virus, i.e. viral antigen. Once the vaccine is administered, the human body's immune system will begin to produce antiviral antigens initiated by the viral antigen.
Why should the seasonal influenza vaccine be taken annually?
Influenza virus constantly changes its surface structures to avoid body defense mechanisms. Therefore, the epidemic viruses are transformed annually and are distinct in different influenza periods.
Vaccines are therefore periodically tailored against influenza viruses. Vaccine viruses are re-evaluated every year.
Should a healthy working-age adult take influenza vaccination?
It is a good idea to take vaccination, especially if in the family there is a person with a high risk of becoming seriously ill. For example, elderly people, pregnant women, children under six months of age and people with long-term illnesses will benefit from the additional protection provided by the vaccine.
Why is the vaccination of risk groups particularly important?
Risk Groups include many chronic illnesses. For example, chronic heart diseases, lung diseases and metabolic diseases. Many diseases and their treatments weaken resistance, and patients also belong to the risk groups. These include, for example, many cancer and rheumatoid arthritis patients.
Influenza vaccinations can reduce 40 to 70 percent of hospitalizations caused by influenza-related illnesses. Early deaths from influenza can be reduced by 50 to 70 percent.
Vaccination reduces not only the risk of getting sick but also the risk of severe influenza. Similarly, vaccination helps alleviate and reduce complications. When a chronically ill person gets a vaccine, he also prevents the underlying disease itself from getting worse.
Is it advisable to get the maximum vaccine coverage and why?
Yes. When the vaccine coverage is sufficiently high, it means stopping the virus cycle and thus creating a so-called flock protector. It means that a person who is unvaccinated or a person with deficient responsive to vaccination indirectly gets additional protection when the virus no longer spreads from one person to another.
Is it better to have an influenza in a "natural way" than having a vaccine?
If you get ill with a disease, immunity or resistance generally lasts longer than the influence of the vaccination. This also applies to influenza. In that sense, there is something true in the claim.
However, decisive in the whole picture is the benefit obtained by vaccination at the level of both the population and the individuals.
Influence can at worst also cause death. When we have a safe and good vaccine that on most people effectively prevent seasonal influenza, so why not use it?
Conventional influenza vaccines can not cause influenza. They do not contain whole, living viruses, but only small influenza virus particles, called viral fragments.
If you get sick with influenza:
Stay home and get rest. Remember to drink plenty of fluids.
If an influenza strikes, its symptoms can be alleviated by the use of self-medication. A healthy adult flu patient can treat the influenza mainly symptomatically. Rest, sufficient fluid intake and fever and pain medication are key ways.
If necessary, you can use a Rhino Horn, or as well as nasal sprays for the nose. If the cough is dry and disturbing, you may stop the irritation with the cough medication.
Additionally, it is important to take care of a good hand hygiene, which includes both careful and sufficiently frequent washing of hands and the use of hand sanitizer.
Taking care of hygiene is important in order not to infect others. To avoid droplet infection, proper coughing technique is essential: it is important to use some kind of cover when coughing, for example a clean handkerchief. It is good to go see a doctor if there is a feeling of pressure in the sinuses or if you feel intense pain in the forehead or pain in the throat. In addition, a suspicion of pneumonia is a reason to contact a doctor.
In children, complication of an influenza can result in a sudden ear inflammation, often requiring antibiotic treatment.
When symptoms are strong, it is good to contact your doctor. The alarming symptoms are high fever, clearly and significantly deteriorating general feeling and changes in symptoms during illness days.
Healthy adults recover from influenza usually within 1-2 weeks.
Disinfection of various surfaces and hands during influenza is an important part of the prevention of influenza in homes, for example. When treating a family member who has already become sick, you should ensure that the risk of infection is as small as possible.
