This is because the antibodies are fully formed only after 2-3 weeks after vaccination. Currently, however, Ukraine imported very few flu vaccines, why vaccinated can be one. Doctors say that it makes sense to get vaccinated throughout the epidemiological season, i.e. from October to may, because the access to vaccines, and immunity is formed of 6-12 months. It is advisable to get vaccinated after you this season’s already had the flu, because you may be ill again, but by a different strain of the virus.
Why the vaccine protects from these strains of influenza and not on other? Annually, the world health organization explores which types of flu will be prevalent in a particular region of this epidemiological season. On the basis of these studies recommendations are developed and manufactured vaccines that allows to speak about actual and efficient protection. Therefore, to get vaccinated against influenza each year, as relevant for the region the strains change each season.

Vaccination does not give absolute guarantee that people will not fall ill to this virus, however, guarantees that the disease would be mild and without complications. If a person fell ill immediately after vaccination, it means that she was already ill at the time of inoculation, and the symptoms manifested in a day or two, as is often the case with SARS and influenza.
Who needs to get vaccinated against the flu in the first place? It is recommended to be vaccinated against influenza to everyone, but there are people who are at risk and need to be vaccinated in the first place. It is health care workers, pregnant women, children, the elderly, patients with chronic illnesses. These categories of persons a high probability to meet with the flu and get his dangerous complications.
