Flu is a viral disease which can easily spread like an epidemic as it is infectious and the virus can spread in any form of contact with the infected person especially in crowded areas.


It is more dangerous because the infected person is liable to pass on the virus to other people even after being cured, because they carry the virus for three to four days and can unknowingly pass it on to healthy people who come in contact with them.

Flu or influenza is a seasonal disease which mostly falls in the winter season so taking the vaccine can protect you from the disease.


As the outbreak occurs every season it is better to take protection against the onslaught of the virus than to suffer from the pains of flu every year. Vaccines have been developed for protecting people against influenza and its after effects and also to stop the spread of flu.


The vaccine has to be taken every year as the strains of the viruses keep on changing so the scientists develop the flu vaccine according to the present strains of virus and expected strains of virus in the future. The vaccines are easily available from the doctor’s clinic, drug stores, any local clinic or at the supermarket.


Types of Flu Vaccine
There are two types of flu vaccines available which can be used by healthy people who are between the age group of five years to forty nine years. One type of vaccine is the injection or the flu shot and the other one is the nasal spray which is called the flu mist.


The vaccine should not be given to children who are six months or below that age. A nasal spray should not be used by people who are suffering from diabetes, asthma, have low immunity due to the use of drugs or immunodeficiency disease. Even pregnant women should not use the nasal spray.


The flu vaccine should be taken at least 2 to 3 months before the season starts, and this will provide enough protection as the effect will continue for at least a year. The vaccine should be taken every year as the previous year virus will easily develop immunity and mutate to form other strains for survival.
