Influenza: Get the (Antigenic) Drift
Have you ever wondered why you need a flu vaccination each year? The National Institute of Allergy and Infectious Diseases explains the ever-changing nature of influenza viruses.

The animation here is really impressive. Bravo, NIAID.
Hi! I am in a medical program and I am graduating from it next saturday. We have to do a presentation about a virus and I chose Influenza. I was wondering if I can use this video to show in my presentation?
this is golden!
Such a good video!
The amount of mercury in the flu vaccine is not enough to be worried about. Far more people have died as a result of not getting the flu vaccine than by mercury poisoning in general, much less the mercury specifically in the flu vaccine. It does imply that you can still get the flu even if you do get the vaccine by addressing the way it mutates from person to person. It's a lot of guesswork to determine which vaccine will be effective against a particular strain, but we do a pretty good job at predicting. The flu vaccine has helped save millions of lives and is very safe.

Seriously?One vaccine maybe not,BUT every year or more??!! PLUS standard vaccines for new born and small children,PLUS the new ones like against cervical cancer for teenage girls PLUS when you travel and many more... And people are wondering WHY so many children have AUTISM this days. And now ,they vaccinating EVEN PREGNANT women with LITTLE,TINY fetus inside ,for which it CAN be TO MUCH,think about that . WOW

+Tyler H Thank you! Besides, ethyl and methyl mercury are totally different.

+Horses4life1001 The mercury in vaccines is ETHYL mercury, not METHYL mercury which is the toxic one. Ethyl mercury does not bio-accumulate, so it doesn't matter if you get a vaccine every year, your kidneys excrete it in matter of days. Who says vaccines cause autism? You have a source for that?

Fermin, you swallowed the company line haven't you? It doesn't take long to find studies on the toxicity of ethyl mercury. Just google it. I'm not going to do your homework for you. You give the impression ethyl mercury is not toxic at all. Comparing ethyl mercury to methyl mercury is like comparing an atomic bomb to a hydrogen bomb. They both can destroy a good part of our world and kill many people.

A single drop of murcury can contaminate an entire river. No thanks.
If antigenic shift and drift happens among two people , wouldn’t that mean a different species of influenza in each person ?

The shift is minuscule from person to person, it doesn't become unrecognizable by immune systems until it has greatly shifted, meaning through many many people over time.

In general the vaccine is very safe and very effective, so I think the message below does not help people understand the usefulness of the flu vaccine. Millions of persons are vaccinated yearly, the efficacy of the vaccine is high in persons with normal immune systems, and the cost is low. Many reasons to get vaccinated; one is to protect yourself, another is to protect your family and loved ones. If you get vaccinated, you don't transmit the virus to your family, children, infants, and elderly.
