It's fairly common knowledge that it's important to get your flu vaccine in time for flu season to keep yourself and those around you healthy. But what happens once you've gotten a vaccine? How does your body process a flu vaccine? Read on to learn more about how flu vaccines work to keep you healthy.

The Basics Of Flu Vaccines

Flu vaccines, just like any other drug, go through a particular set of processes once in the human body. Four processes take place once a drug has been administered: absorption, distribution, metabolism, and excretion. A person's genetics can determine how their body functions during these processes, but most will function basically in the same way.


Absorption: Absorption method depends on the drug type and delivery method, but ultimately allows the drug -- in this case, a flu vaccine -- to enter into the bloodstream.


Distribution: Once the drug is in the bloodstream, it is then delivered to the various areas of the body where it is needed.


Metabolism: Metabolism refers to the process that the body uses to break down and process the drug within the body. For flu vaccines, this results in the creation of materials within the body to help fight flu infection.


Excretion: Eventually, the body will fully process the drug through a process known as excretion. This fully removes the drug from the body over a period of time via natural processes.

Each step in this process is essential to gaining the benefits of an effective flu vaccine. These four processes allow flu vaccines and other drugs to take effect, helping protect the health of the patient and those around the patient as well.

Tips For Purchasing Pre-Filled Syringes

Make sure that you order branded flu vaccines from authorized distributors; for example, order Seqirus flu vaccines from an authorized distributor of Seqirus vaccines. This makes sure that the pre-filled flu vaccine syringes you're receiving are ones that will actually help your patients.
