9 fast facts on the new flu vaccines

Posted February 20, 2018

Nonetheless, the CDC still encourages residents to be vaccinated, as even if it does not stop the transmission of the flu, it can still reduce the acuteness and duration if one does indeed become ill.

This year's vaccine is less effective against the strain of virus making the rounds. Pre-veterinarian and biology sophomore Ciara Kibby said that she knows at least ten people who have gotten the flu, including two of her professors.

"This is a direct response to last year's horrific flu season, which had a devastating impact around the world, and aimed squarely at saving lives", Mr Hunt said in a statement. Sharing is caring, but the flu virus is contagious for 24 hours before symptoms appear, so you're better safe than sorry.

Australia was hit hard by the flu in 2017, with a high number of deaths and hospitalizations.

Preliminary results from the Centers for Disease Control and Prevention show what everyone had suspected, this year's flu vaccine isn't very effective.

What was clear, as early as June, was that we would be in for a nasty flu season in the Northern Hemisphere. That season, public health officials believed that adaptations in egg-grown vaccines were the problem.

So far, Sanofi has made about $617 million in profits since flu season began, and GSK's vaccine business grew by about 76 percent. On Thursday, they also announced the flu shot was about 36-percent effective at preventing flu symptoms this year.

Both vaccines will be available through the National Immunisation Program Immunisation Program following a recommendation from the Pharmaceutical Benefits Advisory Committee.

The FDA is involved in many critical steps in the annual production of influenza vaccines.

Instead, the vaccine may falter over a phenomenon called the 'original antigenic sin'. The FDA is also responsible for ensuring that released lots of influenza vaccines meet appropriate standards. That's because the vaccine has protective qualities irrespective of strain.

These vaccines grew in cells, not eggs.

Hygiene: A number of common actions - coughing, sneezing, touching your nose, mouth, or eyes, and even talking - are some of the most rampant ways of spreading the flu. However, the reality of such a vaccine is likely to still be several years away. The manufacturers are working to try to make better influenza vaccines step-by-step. But this season, new questions arose about the widely adopted egg-based vaccine production process, which was suspected to have reduced the shots' effectiveness, according to a recent New England Journal of Medicine commentary. It could have the potential to allow manufacturers to increase production quickly, if necessary.
