Medical experts: Flu season may be a bad one

Posted December 01, 2017

There are new concerns about this year's flu vaccine.

Doctors at Piedmont Medical Center say they are treating cases of the flu every day.

There was a similar issue three years ago when the vaccine was just 13% effective. Flu viruses typically circulate widely into the spring months, and it isn't clear if the early start will mean an early end or a long season.

One rationale for the arduous flu season may be that this year's presently developed vaccine may have disparate to the flu drain may have wound up propagating creating the vaccinations unproductive at intercepting the outbreak.

The trouble is, the makeup of the viruses can change in the blink of the eye, because virus strains constantly mutate Although researchers have clues about what a virus did previously, they're usually guessing what specific changes will happen next. The vaccine stimulates the body's immune system to make antibodies, which can recognize and attack that specific strain of virus inside the body. Usually, these mutations don't affect the vaccine later on. "I know that in the past, they haven't exactly been as effective, either".

According to an article in the New England Journal of Medicine, the flu vaccine used in Australia, that's pretty much the same as the one in the USA, was only ten percent effective. Australia had a really bad flu season, Fauci said, and they used a similar vaccine to what has been released in the United States this flu season. Eggs are not used in universal flu vaccines.

H3N2 is also a particularly nasty strain, Fauci said.

"The vaccine is still the best bet we have, the best tool we have", Poursina says. This year, H3N2 sickened over 215,000 Australians.

The single best way to prevent seasonal flu is to get vaccinated each year, but good health habits like covering your cough and washing your hands often can help stop the spread of germs and prevent respiratory illnesses like the flu.
