Influenza spreads quickly and easily through communities around the globe. Whether you’re in a well developed urban area or plan to travel to a rural region of a foreign country, there is a risk. The CDC, WHO and other health organizations strongly recommend everyone receive an annual flu shot.
What is a Quadrivalent Flu Vaccine?
A quadrivalent flu vaccine is the most common immunization given. Most of the time, if someone has received the flu vaccine, this is the one they were given.
The vaccine is called quadrivalent because it protects against four different strains of influenza. Each year, the make-up of the disease types the vaccine protects against change to match the strains most commonly spreading. Annual vaccination ensure that you and your community are protected against the virus that will most likely be spreading globally.
How is a Quadrivalent Vaccine Different from a Standard Flu Vaccine?
Today, most flu vaccines are quadrivalent, or protect against four strains. Previous immunizations were often trivalent, or protected against three strains.
The CDC does not recommend any one flu immunization over another as individual needs may vary. An annual flu shot is strongly recommended for almost everyone. Some individuals, like those with immunocompromising conditions, may not be able to receive the flu shot. This is why vaccinating as many people in our communities as possible is important for overall health and safety.
Types of Quadrivalent Flu Vaccines
There are different types of quadrivalent flu shots that a person can receive. As different individuals have different needs, these types exist to help various members of our communities stay healthy.
Standard-Dose Quadrivalent Flu Vaccine
The standard-dose quadrivalent flu vaccine protects against four flu strains. It is generally recommended for anyone who is four-years-old or older. Multiple studies conducted globally show this vaccine to be safe for use.
Preservative-free Flu Vaccine
Different people may be allergic to different things or have different needs. The preservative-free flu vaccine protects those who may be allergic to some of the ingredients in the standard immunization.
High-Dose Flu Vaccine
As we age, our bodies change. The high-dose flu vaccine is specifically designed for individuals over the age of 65 to better protect them from the virus.
Is the Quadrivalent Flu Vaccine Safe?
Yes, all flu vaccines are safe to receive. The CDC and FDA regularly monitor flu vaccinations to make sure they are as safe as possible for everyone who receives them.
Some individuals may be allergic to flu shot ingredients, like eggs. Be sure to check with your vaccine provider at the time of immunization if you have any serious allergies.
Does the Quadrivalent Flu Vaccine Have Side Effects?
As with any medication, quadrivalent flu vaccines may have mild side effects. These can include injection site pain, headache or fatigue. More serious side effects are rare.
Multiple studies show contracting influenza from a flu shot is not possible.
