According to experts, it is the right time when one should get vaccinated for this year's flu. The fall is just around the corner, and the flu season will also begin in very less time. This year's flu outbreak can happen as early as October and can last as late as May.

This year's shots are under produced, and shipments are already arriving at doctor's offices, pharmacies and hospitals. There were concerns last years that the flu shot was not as effective against the strains that were floating around.

The Centers for Disease Control and prevention (CDC) has even listed some vaccines that it recommends should not be used during this flu season.

The reason for which researchers are asking to get flu shots early is that it can reduce the days lost from work because of the virus. They also said that if a person will be vaccinated in advance, he or she will have a lesser risk of getting infected.

As per CDC estimates, healthy adults may be able to infect other people the first day they are infected and before symptoms develop. Flu can also spread to other standing at a distance of as much as six feet away from the infected person.

The virus, which infects the cell of the nose, throat and lings, ether the body by the inhaling of infected droplets or by the touching of one's face after touching the contaminated surfaces. The virus is said to survive on a contaminated surface for nearly 24 hours, said experts.
