2014-2015 flu season: What you should know

ATLANTA — The new flu season could pick up in just a matter of weeks. The Centers for Disease Control says new strains of the flu are always a possibility and can target all ages. That's why the CDC is encouraging everyone to get vaccinated -- not just young children and the elderly. Here are some frequently asked questions to help you stay healthy all year.

What sort of flu season is expected this year?

It's not possible to predict what this flu season will be like. Flu seasons are unpredictable in a number of ways. While flu spreads every year, the timing, severity, and length of the season usually varies from one season to another.


When will flu activity begin and when will it peak?

The timing of flu is very unpredictable and can vary from season to season. Flu activity most commonly peaks in the U.S. between December and February. However, seasonal flu activity can begin as early as October and continue to occur as late as May.


What should I do to prepare for this flu season?

CDC recommends a yearly flu vaccine for everyone 6 months of age and older as the first and most important step in protecting against this serious disease. While there are many different flu viruses, the seasonal flu vaccine is designed to protect against the main flu viruses that research suggests will cause the most illness during the upcoming flu season. People should begin getting vaccinated soon after flu vaccine becomes available, ideally by October, to ensure that as many people as possible are protected before flu season begins.

In addition to getting vaccinated, you can take everyday preventive actions like staying away from sick people and washing your hands to reduce the spread of germs. If you are sick with flu, stay home from work or school to prevent spreading flu to others.


When should I get vaccinated?

CDC recommends that people get vaccinated against flu soon after vaccine becomes available, preferably by October.

It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu.

Doctors and nurses are encouraged to begin vaccinating their patients soon after vaccine becomes available, preferably by October so as not to miss out on opportunities to vaccinate. Those children 6 months through 8 years of age who need two doses of vaccine should receive the first dose as soon as possible to allow time to get the second dose before the start of flu season. The two doses should be given at least 4 weeks apart.


How much flu vaccine will be available this season?

Flu vaccine is produced by private manufacturers, so supply depends on manufacturers. For this season, manufacturers have projected they will provide between 151-159 million doses of vaccine for the U.S. market.


When will flu vaccine become available?

Flu vaccine is produced by private manufacturers, so the timing of vaccine availability depends on when production is completed. If everything goes as indicated by manufacturers, shipments may begin as early as July or August and continue throughout September and October until all of the vaccine is distributed.


Where can I get a flu vaccine?

Flu vaccines are offered by many doctor's offices, clinics, health departments, pharmacies and college health centers, as well as by many employers, and even by some schools.

Even if you don't have a regular doctor or nurse, you can get a flu vaccine somewhere else, like a health department, pharmacy, urgent care clinic, and often your school, college health center, or work.


How long does a flu vaccine protect me from getting the flu?

Multiple studies conducted over different seasons and across vaccine types and influenza virus subtypes have shown that the body's immunity to influenza viruses (acquired either through natural infection or vaccination) declines over time. The decline in antibodies is influenced by several factors, including the antigen used in the vaccine, the age of the person being vaccinated, and the person's general health (for example, certain chronic health conditions may have an impact on immunity). When most healthy people with regular immune systems are vaccinated, their bodies produce antibodies and they are protected throughout the flu season, even as antibody levels decline over time. Older people and others with weakened immune systems may not generate the same amount of antibodies after vaccination; further, their antibody levels may drop more quickly when compared to young, healthy people.

For everyone, getting vaccinated each year provides the best protection against influenza throughout flu season. It's important to get a flu vaccine every season, even if you got vaccinated the season before and the viruses in the vaccine have not changed for the current season.


Can I get vaccinated and still get the flu?

Yes. It's possible to get sick with the flu even if you have been vaccinated (although you won't know for sure unless you get a flu test). This is possible for the following reasons:

You may be exposed to a flu virus shortly before getting vaccinated or during the period that it takes the body to gain protection after getting vaccinated. This exposure may result in you becoming ill with flu before the vaccine begins to protect you. (About 2 weeks after vaccination, antibodies that provide protection develop in the body.)

You may be exposed to a flu virus that is not included in the seasonal flu vaccine. There are many different flu viruses that circulate every year. The flu vaccine is made to protect against the three or four flu viruses that research suggests will be most common.

Unfortunately, some people can become infected with a flu virus the flu vaccine is designed to protect against, despite getting vaccinated. Protection provided by flu vaccination can vary widely, based in part on health and age factors of the person getting vaccinated. In general, the flu vaccine works best among healthy younger adults and older children. Some older people and people with certain chronic illnesses may develop less immunity after vaccination. Flu vaccination is not a perfect tool, but it is the best way to protect against flu infection.


Is there treatment for the flu?

Yes. If you get sick, there are drugs that can treat flu illness. They are called antiviral drugs and they can make your illness milder and make you feel better faster. They also can prevent serious flu-related complications, like pneumonia.
