Influenza Vaccine Facts

The influenza shot is an inactivated or killed vaccine and is usually changed each year to keep up with the most common strains of the influenza virus that are circulating and most likely to cause infections.

The influenza vaccine is available for children over the age of six months. To produce a good response, the first year that they get it, children under nine years of age need two doses of the vaccine given at least one month apart. Children over nine years and younger children who have previously had a flu shot only need a single injection each year.

Flu shot reactions or side effects are usually mild, and may include soreness, redness or swelling where the shot was given, fever, and/or aches, and usually only last for 1-2 days. Children under 3 years should receive a 0.25ml dose of inactivated flu vaccine. Children over 3 years and adults should receive a dose of 0.5ml.

More serious side effects can rarely include a life-threatening allergic reaction.

Should You Fear H1N1 Swine Flu?

With increasing numbers of deaths in Mexico, and more incidents of possible swine flu being identified across the world, we seem to have little control over this advancing disease, possibly pandemic, giving us reason to fear it. But should we really fear the swine flu?

No. Fear is unnecessary. But a healthy respect is definitely called for.

A "Public Health Emergency"

It does sound frightening -- those words -- "Public Health Emergency." And calling swine flu a public health emergency most definitely gets our attention.

Behind those words, though, is the fact that the actual declaration is really a vehicle for making money available and suggesting that local governments begin using their predetermined plans for managing public health problems. It doesn't mean there is a crisis.

Let those words remind you to take precautions yourself. But don't be afraid of them.


Flu is Flu

H1N1 swine flu is one more strain of flu. It sounds really scary because it originally came from pigs, and that creates some mystery around it. It also sounds scary because we don't have any vaccine to protect those who are most vulnerable.

But it behaves like other flus. We catch it the same way, and we can protect ourselves the same ways. We can make choices to protect ourselves and our families.

Do you fear the seasonal flu? Probably not. And this flu is really no more frightening than seasonal flu. Seasonal flu takes tens of thousands of lives each year. Deaths from H1N1 swine flu have not approached those of seasonal flu.


Pandemic Describes Geography Only

We hear the word "pandemic" used by the media and that reminds us of history class in high school. It sounds like it means millions of people might die. But that's not what it means at all!

Pandemic simply means it is found large groups of people in many countries around the world. Pan comes from Latin and Greek meaning across or around. Demos means populations or people. Pan-demic. Geography and demographics. Not deaths.

What About Those Face Masks?

When I see those masks on the people on TV, it reminds me of SARS and bird flu in China a few years ago. Again, that was scary because so many of the people who contracted those diseases did die.

Masks just keep the wearers from inhaling the water droplets that might be breathed out by someone who has the flu bug. Or when worn by someone who has any upper respiratory disease, they may contain some of the spread of that illness. They aren't a bad idea, but they don't indicate that the flu is any more dangerous than any normal flu.

Thousands of people die of seasonal flu each year, but we don't all wear masks.

Why Does It Seem Like We are Unprepared?

Another reason some fear the swine flu is because, unlike seasonal flu, we don't have vaccines available, people are still traveling, and we seem unprepared to stop it.

Again, this fear is unwarranted. Thousands of strains of viruses could potentially cause flu. We have no way of creating vaccines for all of them, nor would anyone ever be willing to be vaccinated against them all.

We do have two drugs available to help with symptoms, which the CDC tells us is in plentiful supply. Relenza and Tamiflu, both of which are used during seasonal flu seasons each year, are also useful for helping swine flu patients, too.
