In Australia this past flu season, the problem did not appear to be a mismatch between the flu strains that were circulating and those that the available vaccine protected against, Fauci said. This seems to be the case with the batch of flu vaccines given out this year, Anthony Fauci, the director of the National Institutes of Health's National Institute of Allergy and Infectious Diseases, told a local Washington DC radio station. The peak of flu season has occurred anywhere from late November through March.
The Louisiana Department of Health says flu activity is picking up significantly across the state. The vaccine that the Australians received was only 10 percent effective.
Researchers discovered an overlooked mutation in two of the viral strains used in the vaccine. "There should be a flu vaccine out there that is suitable for everybody in that age range". Even worse, almost three-quarters of the 1,544 laboratory-confirmed cases of flu seen in the US since October 1 were of the H3N2 variety, according to the Centers for Disease Control and Prevention. The influenza A virus was the most common flu strain.
The annual flu vaccine development process begins several months before each flu season.
For many, the flu vaccine is covered under some form of insurance or through Medicare Part B - and often with no out-of-pocket cost. There are clinical trials being conducted.

Myth 1. The flu shot gives you the flu. "We're not saying it's a great vaccine", Bregier said.
Though researchers are working hard behind the scenes to develop more effective vaccines, you should still aim to be proactive about your health. That could eliminate the need for people to get new flu shots each year. "However imperfect, current influenza vaccines remain a valuable public health tool, and it is always better to get vaccinated than not to get vaccinated", wrote the authors of the perspective. They could be several flu seasons off, but Fauci said he has "made this a high priority" in a budget that the Trump administration has targeted for 21 percent budget cut.
