Overview: Fluzone Influenza Vaccine by Sanofi


Strains A And B

There are a number of influenza strains, but they’re primarily categorized between “A” and “B”. Fluzone by Sanofi has produced vaccines for both strains. They are administered to individuals who are at least six months old, and under sixty-five. For adults of sixty-five and over, a high-dose vaccine is administered. Between eighteen and sixty-four, an intradermal vaccine is administered.

A high dose vaccine is exactly what it sounds like: a higher amount of the antigens (read: inert influenza virus) is administered, which triggers a stronger response. Intradermal just means the skin is penetrated. This is a shot, or a prick that has been dipped in a solution of the vaccine. With Sanofi’s Fluzone influenza vaccine, intradermal means “shot”. The intradermal vaccine contains three strains of influenza, and as a result there is a more red, swollen firmness surrounding the site of injection than is seen with the Fluzone version.

What Makes Up A Flu Vaccine?

Vaccines work by introducing the immune system to what are called antigens. This’s a fancy word for describing inert portions of the influenza virus that are oftentimes restrained chemically. Because of the way in which antigens are contained–keeping them from being full-blown viral entities–there can be allergic reaction to administration of influenza inoculations. Any known allergic tendencies should be reported to a medical authority long before vaccines are administered. In any event, should a vaccine be administered in the normal way, without allergic reactions to confuse things, then the body’s immune system will encounter the antigens, latch onto them, and learn how to fight against them. This makes it so that when the non-restrained viral antigens are encountered after the flu shot has been taken, the body already knows how to ward them off. White blood cells are the body’s bouncer, and antigens are that guy who shouldn’t be in the club. Vaccines are a tip-off to the bouncer not to let that guy in before he shows up. But sometimes that unsavory character shows up with a group of friends, and things get interesting. That’s kind of a good equivalent metaphor to what’s going on in the vaccine world right now, because influenza virus is constantly shifting, constantly changing, and constantly spreading. There has been no diminishing of mortality-rates which have a root related to influenza. The flu just keeps marching on. Protecting yourself as best you can is wise.

When To Get Vaccinated

Sanofi’s Fluzone vaccine will always come with some measure of side effects, because the antigens administered trigger that aforementioned immune system response. You’ll get a tiny version of the sickness you’re preventing against with any vaccine, and influenza is no difference. Severity of infection is where things are separate. The sickness you get from the vaccine prevents you from a worse infection than you would have without said inoculation. But this means you must be in good health when you get the vaccine. Summertime is ideal, because schedules are more relaxed, the sun is constantly administering Vitamin-D in levels which are received more often by people because days are longer and outdoor activities increase. Immune systems are generally at their peak operational ability in the summertime. This means vaccinating at this apex is definitely to be recommended. Additionally, most people tend to put off getting the flu vaccine until flu season actually starts, meaning availability drops. If you get your Sanofi Fluzone vaccine in the Summer, it’s more likely there will be available quantities, and that your body will be healthy enough to properly receive it. The one thing you don’t want to do is nothing.
