This is a type of influenza A. The strain that we're most concerned about right now is a strain that's slightly different from the strain that is in the vaccine. This is what is known as the "drift" strain.
This year's influenza vaccine for the northern hemisphere contains material that will protect against three strains of flu, H3N2 Panama, H1N1 New Caledonia, and Influenza B Hong Kong.
The strain that we're most concerned about, that is a drift version of H3N2 is called the Fujian strain. It's very similar, it's just drifted a little bit from the Panama strain, and our animal studies suggest that the vaccine will provide cross-protection against this strain. In the past this has happened. It's a very common thing. As flu strains gradually evolve in people, we don't always have exactly have the same strain as a vaccine that is circulating in the community and our experience so far, historically, has been that whatever the drift is, that the vaccine will still provide some cross-protection.
So we're optimistic that would be the case this year but of course we'll be watching that very carefully and we'll know more as the flu season evolves.
The point is that people need to get their flu shot. This is the time for Americans to really step up to the plate and get vaccinated against influenza, especially because this could be a worse-than-usual flu season and especially because we have this particular strain circulating and in some previous situations H3N2 strains have been associated with perhaps more severe disease. "Week 46 - Week Ending November 15Week 47 - Week Ending November 22Should You Get the First Flu Shot Available?http://www.cdc.gov/nip/flu/high_priority.htmAt a glance: Almost everyone can benefit from a flu shot. But some people have a greater need to be protected, and they should make a special effort to get this protection each year, early in the flu season (October or November). Check the high-priority groups described on this page, and find out if you are one of these people. High risk of severe illnessAdults 65 years old or older. Even if you are in excellent health, you have a greater risk of complications if you get the flu. To keep your good health, get your shot in November or December!
Children 6-23 months old. Young children are among the most likely to be hospitalized for influenza. Even if your child is in excellent health, be sure to get this protection to keep the good health!
Adults and children with chronic (on-going) health problems, including:
asthma or other on-going lung problems
kidney disease
heart disease
diabetes
Adults and children with an illness (such as HIV/AIDS) or who are taking medical treatment (such as chemotherapy) that can lower the immune system.
Children and teenagers between 6 months and 18 years old who are receiving long-term aspirin therapy have a risk of getting Reye syndrome if they get the flu; they should also get a flu shot early in the flu season.
Women who will be at least 3 months pregnant during the flu season need an early flu shot.
Can give flu to those at high riskContacts for those at high risk. Adults and children who are household contacts or care-givers for others at high risk of severe illness from flu should get flu shots as soon as possible, to protect those they are caring for.
Healthcare workers. Your daily exposure to sick people makes you far more likely to get (and give) the flu. Remember, your patients depend on you to stay healthy so you can help them stay healthy.
Household contacts or care-givers for children under 2 years old. Infants younger than 6 months old cannot take a flu shot, but they can get the flu. This illness can be dangerous for a very young child. Their best protection is non-exposure; if those around them do not get the flu, they cannot give it to the children they are caring for.
Anyone who lives in a nursing home or chronic-care facility for people (of any age) with chronic medical conditions should also be one of the first to get a flu shot.
Your child's very first flu shot Children 6 months-8 years old who are getting their first flu shot ever need a booster shot one month after the first dose of vaccine. For best protection, be sure your child gets the first shot as early as possible; the first dose should be administered in October.
People 50-64 years old, a special groupBased on your age alone, you are not at high risk of flu-related complications yet. However, approximately 10-13 million adults (24%-32%) in your age group have one or more high-risk medical conditions. Even if you are in excellent health, you should be sure to get a flu shot in to avoid missing work because of the flu and to prevent additional medical visits and medication. The flu shot is among the preventative measures people over 50 need to take to stay healthy.
