Nobody likes to get sick with flu, and the world community is concerned about the possibility of an epidemic, since the risk of catching flu still remains. This is because the flu virus constantly changes its formula, and flu vaccines can protect a person from only two, maximum three strains of flu - type A and B. Now doctors have invented a new vaccine that will protect people from four strains of flu. This is a real revolution in health care.

A useful invention for all mankind
The quadrivalent vaccine, developed this year, protects against two strains of influenza A and two strains of influenza B, and is intended for adults and children ages 2 to 49, the U.S. Food and Drug Administration (FDA) said. It is a new nasal spray vaccine that provides weakened strains of the virus in the body.
Previously, all flu vaccines contained two strains of influenza A and one strain of influenza B, which were chosen annually by medical experts based on the virus's potential to spread worldwide. By adding an extra strain of influenza B, the vaccine is more likely to protect against disease, FDA officials say.
Flu vaccine will protect children and pregnant women
"Influenza B virus illnesses affect children, especially young children and school-aged children, more than anyone else," said Dr. Karen Midthun, director of the FDA's Center for Biologics. The vaccine will protect them from the flu if they get vaccinated on time. Vaccination season is in full swing right now, with October and November being the best months to get vaccinated.
The severity of illness and death from influenza varies widely from season to season, so vaccination is the best way to protect against influenza. Between 1976 and 2007, influenza-related deaths ranged from a low of about 3,000 to a high of about 49,000, the FDA notes. That's why it's important to get a protective flu shot every year.
Does the new vaccine have any side effects?
The FDA says side effects from this vaccine may be similar to those from previous vaccines. They include runny or stuffy nose, headaches, or sore throats. But compared to the damage caused by the flu, these are not that bad.

How to protect yourself from the flu other than vaccination?
In addition to getting vaccinated, normal daily activities combined with vaccination can significantly reduce the risk of contracting the flu. What can you do to reduce your risk of contracting the flu? First of all, washing your hands with soap and water will help. And before you wash your hands, you should avoid touching your eyes, nose, and mouth (to prevent the spread of germs that like to live on mucous membranes). You should also avoid close contact with sick people.
If you are already infected with the flu virus, stay home for 24 hours after the illness has passed to avoid infecting others.
The flu vaccine is a good way to reduce your health risks, especially considering that pregnant women and children who haven't been vaccinated are five times more likely to get the flu than other people.
