Influenza vaccine, recognize the benefits of side effects

Influenza vaccine is the best protection against influenza, especially during the transition season, which can cause influenza. Although it sounds like a mild illness, the flu can actually cause serious problems for some people.
Influenza is an acute and contagious viral infection that attacks the airways. There are two subtypes of influenza virus, namely subtype A and B. This virus spreads through the air and physical contact, for example by shaking hands with the person being captured. If left untreated, this disease can trigger a recurrence of accompanying diseases such as asthma or secondary infections due to bacteria. Influenza complications are more at risk for the elderly, pregnant women, children aged 6 months to 5 years, medical staff and people suffering from certain diseases, such as HIV / AIDS, chronic heart or lung disease and asthma.
