The flu season of 2017 is almost here and people are on their way to get their annual flu shots. From year to year, the flu virus can change. It can grow stronger and become more resistant to the effect of certain types of vaccines. That’s why there have been a few changes compared to the vaccinations that were given in the past.
Here are the latest recommendations for flu vaccines:
Avoiding the use of the nasal spray vaccine due to its ineffectiveness over the past three to five years.
Most doctors are recommending only the injectable form of the vaccines because they seem to be more effective and it ensures each patient receives the proper dosage with each delivery.
Trivalent vaccines have been modified to include both H1N1 and H3N2 forms of the flu shot that were used last year. These variations are better able to deal with exposure to strains of the flu that have evolved or progressed and subsequently increased in strength.
Quadrivalent vaccines include those in the trivalent form as well as both B/Victoria and B/Yamagata antibodies. A quadrivalent vaccine covers a wider range of viruses than trivalent forms.
The formula for each vaccine has been updated compared to the formulation that was used during the 2016-2017 flu season. The upgrades include new antibodies to help protect individuals from the new variations that are being found in older strains. As a strain evolves gradually, the vaccines used to protect against them must constantly be evaluated to ensure the patient receives the highest level of protection possible.
Small children and the elderly are the most likely to have adverse effects after contracting the flu virus. It’s important that all of the options be discussed with your primary care physician, so that the right flu vaccine can be chosen for you and your family’s particular needs.
