Intradermal flu shot like other flu vaccines, is injected into the skin instead of the muscles. Medics usually use a smaller needle when administering the intradermal flu shot. As well, it does not require as much antigen to be effective as the regular flu shots. An antigen is that part of the vaccine which assists your body to come up with protection against the flu virus.
Comparing flu intradermal flu vaccine to other flu vaccines
There is no difference between the safety profile of the intradermal vaccine and the regular flu vaccines when it comes to their safety profiles. It is developed to protect an individual against four influenza viruses just all the quadrivalent flu vaccines. Also, the mechanism in which it works in the body is similar to that of a regular flu shot.
The size of the needle used for this vaccine is nearly 90% smaller than the needles which are used for the regular shots. This comes in handy for those who freak out in the presence of needles. Besides the size of the needle, a noteworthy feature of the intradermal vaccine is that it requires about 40% less antigen than the rest of the flu vaccines. The advantage of this is that the rest of the antigens can be used to make other vaccines.
Who can receive the intradermal flu vaccine?
The Fluzone intradermal trivalent flu shot is meant for administration in the population aged 19 to 64. The dermis of the skin where it is administered through is rich in dendritic cells. The dendritic cells are handy in assisting the body to build a strong immune response. The shot is free from preservatives. The immune response of the intradermal flu vaccine is similar to that of the regular shot despite the disparity in the number of antigens.
Risks associated with intradermal flu vaccines
The side effects from the intradermal flu shot are similar to the ones experienced when an individual receives the traditional flu shot. However, certain side effects have been more common because of the way it is administered. These are some of the effects you will see on the injection site on your skin after receiving the shot:
The risk of the intradermal flu shot causing serious health problems is something that is not often witnessed. It is extremely rare to record serious health implications brought about by the administration of the flu shot yearly. That is enough reason to say that it is safe and recommended for persons. Sometimes, and just as in any other medicine, vaccines can lead to some severe allergic responses. It is, however, noteworthy that these cases are extremely rare. The mild symptoms usually disappear within a short time like in about three to seven days.
Even as you may not experience severe complications in many instances, you must provide your doctor with the information of your past medical history. For instance, if you have had an allergic reaction to a flu vaccine, you should let the physician know so that they can advise accordingly. Again if you have had the Guillain Bare syndrome, then you should let out that information to the doctor for appropriate advice.
Where to get the vaccine
Influenza vaccines are always available throughout the year and most especially during the seasons when the flu vaccines are most prevalent. You can check with your local passport health clinic to find out whether they have the shot. If they have it, ensure that it is administered to you, so you are not vulnerable to flu infection.
