Do I need a vaccination against influenza
Flu season in the bow, how to protect themselves from the virus? Especially when all around sneeze, cough and blow your nose. In the last few years a great popularity began to use the flu vaccine. However, opponents of these vaccinations today is not less than supporters.
What is influenza
Flu - is a virus that spreads rapidly and with a high probability of causing serious complications. The flu can mutate and acquire various new modifications, which leads to uncontrolled proliferation of the infection (epidemic, pandemic). The main difference between the flu and other respiratory infections (ARI) is its ability to change quickly and accumulate mutations, circulating naturally in animals and birds. His new subtypes may elude the defensive reaction of our immune system that causes the development of a large number of complications from influenza.
The most common seasonal flu, but there are flu viruses that can cause a pandemic (an epidemic), and they differ from each other. Seasonal flu viruses tipiruyut, and they create a vaccine based on the most likely strains in a certain season. Primarily, this fall and winter, but occasionally observed flu and other seasons. In some tropical countries, influenza viruses circulate throughout the year, reaching one or two peaks during rainy seasons. But the influenza virus that causes a pandemic, to create a vaccine impossible. This is due to the fact that, circulating in nature among animals and birds, influenza virus mutates.
The risk group includes those who are in contact with more people: nurses, workers of transport services, reporters, military, as well as children in preschool, school children, students and seniors older than 60-65 years. Influenza viruses can accumulate different mutations to mutate, change their properties and cause complications in the event of illness. But this issue has not yet been well studied. There is a perception of the possible places the reservation of influenza viruses. We are talking about people with special, gipoergicheskim immune response - when the aggression on the part of the patient's immune system stronger microorganisms. That is the person, such as the flu, recovered, and in the body of the virus was not completely defeated. The body inhibits the flu virus, the person is no longer sick, but the minimum activity of the virus remains. Therefore, the virus can persist in the body for a long time, thus being able to mutate. Subsequently mutated virus can be spread when a person contacts the carrier.
Mass vaccination campaigns are carried out against seasonal flu strain and, unfortunately, does not protect against the strain causing the pandemic. Currently, foreign vaccines available "VAXIGRIP", and from domestic - "Grippol plus" and "Ultriks". For the patient, the cardinal differences between the vaccines there, but "Grippol plus" contains smaller amounts of antigen, which is recommended by WHO. Also it includes polyoxidonium, which, according to the manufacturer, makes up for the number of antigens, but studies proving its effectiveness, it is currently absent. If we approach the issue carefully vaccination, the complications are minimized. Preferably instilled in medical facilities where there may be provided an ambulance in the case of, for example, allergic reactions.
Main contraindication - allergic reaction to chicken protein, and aminoglycoside antibiotics and polymixin (for vaccines containing them). Also vaccination is contraindicated in SARS or exacerbation of chronic process, in the case of heavy reaction or complications of the previous administration of the vaccine. One can not be instilled in systemic connective tissue diseases, adrenal disease and hereditary degenerative diseases of the nervous system. With regard to vaccinations for children - the rules prohibited to vaccinate children under the age of 6 months, and in the period from six months to two years, vaccination takes place in two stages in order to create immunity tension.
In addition to good preventive vaccination is early hardening of the body, and timely treatment of chronic diseases, particularly upper respiratory tract and bronchial-pulmonary system. And conventional wisdom such preventive measures as an additional intake of vitamins and homeopathic remedies will not have a significant preventive effect.
