Intradermal flu vaccines belong to a new wave of vaccinations which, when it comes to the annual ritual of choosing a flu shot, have greatly broadened the array of options open to consumers. You can prevent having flu with vaccination that is why a team of home doctors in Perth advise to get vaccinated.
What Sets an Intradermal Shot Apart?
Where the majority of vaccinations are delivered deep into a patient’s muscles via an intramuscular injection, intradermal shots are instead injected into the skin. In turn, this defining characteristic has a direct influence on needle length.
Since intradermal needles need only penetrate the topmost layers of skin, they are 90% smaller than their intramuscular equivalents. In concrete terms, this translates into a needle length of only 1.5 millimeters.
Antigen efficiency is another feature of intradermal shots. Antigens are a vital component of vaccines as they actively stimulate the body to protect itself against viruses. It’s no exaggeration to say that, in comparison with regular shots, intradermal vaccines make much more efficient use of their constituent antigens. Indeed, all in all, the antigen levels of intradermal shots are typically 40% lower than those of regular shots. Rest assured, this disparity comes at no cost to overall efficacy.
Intradermal shots are what are called quadrivalent vaccines. Effectively, this means that they protect against four different strands of the flu virus. The decision over which specific strands to include is informed by predictions concerning the prevalence of flu viruses. This predictive input helps best ensure that the resultant vaccine is ideally formulated to deal with an upcoming winter’s most widespread flu viruses.
Does it Work?
Intradermal vaccines are approved for use among people aged 18-64. Studies show that for this population intradermal vaccines are just as effective at stimulating an immune response as more traditional intramuscular alternatives.
Are There Any Serious Risks?
In general, the risk of a serious complication resulting from an intradermal shot is extremely small. Having said that, as with any medicine, the possibility cannot be entirely ruled out.
Additionally, anyone concerned that the shot could actually cause flu can rest easy. Intradermal shots are in fact classified as inactivated vaccines since the constituent flu virus is actually already dead.
Potential Side Effects
The most common side effects occur in and around the injection site. Indeed, in this area, it’s not unusual to see signs of redness or swelling, to experience pain or itching, or to find toughened skin.
Nearly all of these side effects are more common following an intradermal as opposed to regular shot. The exception, however, relates to the lower levels of pain experienced by recipients of intradermal shots.
Additionally, patients may also experience headaches, muscle aches, or tiredness. On the plus side, such symptoms are typically short-lived and tend to clear up within 3-7 days.
When actively considering intradermal flu vaccines as an option, it can be important to consult with medical professionals before making a final decision. This is particularly true in cases where a patient happens to be allergic to the flu vaccine or its constituent ingredients. Or moreover, if they have previously suffered from Guillain-Barr Syndrome.
