Older Australians will be given two free, stronger flu vaccinations in a bid by the government to prevent another deadly influenza outbreak which past year killed more than 1000 people.
In 2012-13, the H3N2 component of the flu vaccine was effective in just 39 percent of people.
The CDC found that children fared better - the shot was 59 percent effective against H3N2 for them - but kids are also more susceptible to infection in the first place.
More than 1100 people across Australia died from the flu a year ago, with a lot of them over 65.
Health Minister Greg Hunt said these new vaccines have been specifically designed for those over 65, as their immune systems respond less effectively to the generic vaccines. One of the flu strains spreading this season, H3-N2 is affecting children more than most. "However, the virus has mutated between the time they picked the strain, and the time they manufactured the vaccine".
The effectiveness of the vaccine depends on what strains of the flu are circulating, how virulent they are, how well the vaccine matches to the circulating strains and, finally, how much protection it provides against those strains.
Unlike in other areas of the country, there have, fortunately, been no pediatric flu deaths this season.
The flu is a contagious respiratory illness caused by the influenza virus, according to Brunader. The FDA is committed to working together with the scientific and medical communities to better protect the public against the flu and apply lessons learned to next season's flu vaccines.
"Clearly we need either better vaccines or better use of current vaccines, choosing those products that might work better", he said.
Shivering chills, body aches, fever, fatigue - it's flu season in Shelby County and across the nation.
The flu is the culprit behind 67.9 out of every 100,000 hospitalizations as of this week, surpassing rates from the 2014-2015 flu season.
Once the strains are selected, the FDA produces materials in our laboratories that are critical for making the vaccine.
Three of four children who died had not received the flu shot, the CDC's acting director said.
While most flu-seasons last about 16 weeks, some have gone as long as 20 weeks. These include providing some manufacturers with the seed viruses used for further vaccine manufacture and the critical potency reagents needed to ensure that influenza vaccines made by one manufacturer are similar to those made by another.
Of course, the Holy Grail would be the so-called "universal influenza vaccine", at least universal across all those influenza A strains.
These vaccines grew in cells, not eggs. 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.
