An autumn time is coming and we are most prone to catch a cold and different virus diseases which affect mainly the respiratory tract what makes our everyday life very unpleasant. We feel quite tired, inefficient, we are forced to clean our nose all the time and the cough does not allow us to have a rest even during our night sleep. It is a time of influenza.
Influenza is an acute virus disease which spreads quickly from man to man through air way. It belongs to serious health problems which can cause difficult health states even death by high risk groups. According to World Health Organization about 1 billion people have got an influenza yearly, from them 3 to 5 millions have a serious course of disease. The risk of origin of serious complications is the highest by little children, seniors and by people with serious chronic diseases of the respiratory tract, cardio-vascular system, metabolic, nephric and immune disorders.
Who should get vaccinated?
Vaccination should be first and foremost aimed at people by who the probability of complications is the highest or at those who are most exposed to risk of infection. The high probability of complication is by persons with other, mainly chronic disease, by persons with weakened immune systems and by persons older than 65 years as well.
The vaccination is equally effective by healthy people, morbidity is reduced in 70 to 90%. Vaccination against influenza is recommended to all children from 6 months to 3 years. Protected by vaccination should be also sportsmen and travellers to foreign countries in time of assumed flu epidemic.
Who should not get vaccineted?
The vaccination should be put off by patients with feverous disease or acute infection. Persons allergic to hen eggs should not be vaccineted. However, today vaccinations for allergic people are available by production of which the virus is reproduced on other cells than hen origin. Vaccination is generally not recommended to women in first trimester of pregnancy and to children younger than 6 months of age.
Why is the annual vaccination recommended?
The level of antibodies which is developed by vaccination declines over time and it can be too low for providing protection for the next year too. Influenzal viruses are also constantly subjected to genetic changes and the immunity gained after previous influenzal infection or after vaccination in previous year does not have to protect against changed influenzal viruses. As the influenzal virus is changing, the inoculator has to be updated every year to contain the most up-to-date strains of influenza virus.
How does the inoculator protect you?
Following the vaccination an immune system starts to produce antibodies against virus proteins of vaccination species. If the human is infected by real virus, these antibodies are linked to virus particles which invaded to organism and they are done away sooner than they damage tissue, so the result is, that people will not get ill or the disease pass only gently. The sufficient protective level of antibodies is developed in 10 to 14 days after vaccination.
When is the most appropriate time to get vaccinated?
In the southern hemisphere is the most appropriate time to be vaccinated from half September to the end of November. If you are vaccinated later it can happen that the inoculator does not have an sufficient time to secure an immune answer. Your general practitioner who will realize the vaccination will provide you more informations.
How effective is the inoculator against influenza?
An effectivity of vaccination is in prevention or reduction of the process of disease. An effectivity of inoculator against influenza depends on immune system of certain person, on age of vaccinated person, level of similarity of vaccinated virus and virus circulating in population, (sub)type of virus and on legth of time between vaccination and exposure to influenzal virus. These factors cause that it is difficult to say with certainity, how effective is the influenzal vaccination. Generally we can say, the vaccination will prevent from disease by 80% of young adults and is little bit less effective by older people.
Can you get flu even though you were vaccinated?
Yes, you can, especially by older adults if they were infected short after the vaccination. However, by those persons who were infected after vaccination it is probable that the disease will pass gentlier, without complications and it is less probable that it will require hospitalization or it will end by death.
If you want to support your organism immunity and avoid virus diseases we reccomend you also the application of high-dose vitamin C (7,5 g) which is applied in repeated small short-term infusions to the vein. Before its application it is needed to inform by your doctor, if its application is not improper for you. For example patients with an inclination to uratoma creating can not use this treatment, eventually they need som extra examinations before its application.
In the end it is needed to remind the travellers who will decide to visit exotic countries during autumn and winter, that they should not forget the vaccination against infections which could make their stay in the country unpleasant.
If you will think of your health and its prevention an autumn will be beautiful also for you and it will be full of fresh colours which you can enjoy even with the coming of this year’s Indian summer.
