With flu season approaching, it's time for vaccination

Health Officials Flu Shot May Only Be 10% Effective This Season

The costs of flu vaccines vary on insurance plans, but many planes cover the vaccines at no cost, according to Crow. Complications of the flu include bacterial pneumonia, ear infections, sinus infections, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes, according to the Centers for Disease Control and Prevention (CDC).

Flu does constantly evolve, forcing new vaccine to be brewed each year to match the strains specialists expect to cause most illness.

Widespread flu activity is now in four states where past year there were none at this time, according to the Centers for Disease Control and Prevention.

This year, however, the virus appears to have mutated rendering the vaccine only about 10% effective.

'That's what happened in Australia and it is likely that that's what we're going to see here, ' he added.

"The very process of how we make the vaccine creates an unanticipated, nearly accidental mismatch, which is what happened in Australia this year", Fauci said in an interview.

The figure below shows peak flu activity for the United States by month for the 1982-1983 through 2015-2016 flu seasons.

The high prevalence of influenza A viruses in recent years is a particular problem for the current generation of vaccines, Fauci and his colleagues wrote.

"Preventing the flu in as many people as possible is our first priority", says Dr. Crosby.

The vaccine now being administered to Americans uses the same formulation.

Getting vaccinated later; however, can still be beneficial and vaccination should continue to be offered throughout the flu season, even into January or later. And it states getting the flu vaccination is the single best way to protect yourself from the flu and its consequences.

The production of universal vaccines entails no such risk. But time is running out for you to get inoculated and have that two-week period of building up a resistance to the flu.
