Give Yourself Immunity

This year, the 2009 H1N1 flu (aka, the Swine Flu) is grabbing all the headlines. But that doesn't mean you should ignore the less newsworthy seasonal flu. According to the Centers for Disease Control and Prevention (CDC), about 200,000 hospitalizations and 36,000 deaths result each year from seasonal flu alone. Yet over 50 percent of people surveyed in the 2009 CVS Caremark Health IQ study reported that they didn't get a flu shot last year. "A flu shot can save hundreds, if not thousands, of dollars in medical care costs and prevents the aches, chills, fever and more serious complications of flu." said Troyen A. Brennan, M.D., Chief Medical Officer for CVS Caremark. The bottom line: "Flu shots save lives and they prevent the illness that flu brings to millions of us every year." Here's what the CDC recommends:
Does everyone need to get a flu shot, or just those at high risk for seasonal flu?
In general, anyone who wants to reduce the chance of getting the flu can get vaccinated. The Centers for Disease Control (CDC) lists the following criteria for people they consider at high risk for complications from the flu or they live or care for someone who's at high risk.
Children aged 6 months to 19
Pregnant women
People 50 years of age and older
People of any age with certain chronic medical conditions
People who live in nursing homes and other long-term care facilities
People who live with or care for those at high risk for complications from flu, including:
- Health care workers
- Household contacts of persons at high risk for complications from the flu
- Household contacts and out of home caregivers of children less than 6 months of age (these children are too young to be vaccinated)
I got one last year, do I need a shot this year?
Flu viruses change from year to year, which means two things. First,you can get the flu more than once during your lifetime. The immunity that is built up from having the flu caused by one flu virus straindoesn't always provide protection against newer strains of the flu.Second, a seasonal flu vaccine made against flu viruses going aroundlast year may not protect against the newer viruses. That.s why the fluvaccine is updated every year.
Will the seasonal flu vaccine protect me against the H1N1 flu and other viruses?
The seasonal flu vaccine is your best protection against seasonal flu viruses. However, the 2009 H1N1 flu is a new and very different flu virus spreading worldwide. The seasonal flu vaccine will not provide protection against it. A 2009 H1N1 vaccine is currently in production, but it is not intended to replace the seasonal flu vaccine - it is intended to be used along-side seasonal flu vaccine.
Does the seasonal flu vaccine work the same for everyone?
The seasonal flu vaccine is the single best way to prevent seasonal flu, and vaccination is the main tool used to protect people from seasonal influenza. A number of studies have shown that the seasonal flu vaccine works, but how well the vaccine works can change from year to year and vary among different groups of people. The ability of the seasonal flu vaccine to protect a person depends on at least two things: 1) the age and health of the person getting the vaccine, and 2) the similarity or "match" between the virus strains in the vaccine and those being spread in the community.
