The authors want that however imperfect, though, current influenza vaccines remain a valuable public health tool, and it is always better to get vaccinated than not to get vaccinated. This year, there are concerns that the shot is not very effective, but experts are still encouraging people to get it.
Public Health Nurse Brett Goudreau says "the implications of Influenza A (H3N2) for North America are not yet clear".
The paper says the implications for the Northern Hemisphere are not clear but states that since most of the USA influenza-vaccine supply is now produced in eggs and the composition of the 2017-2018 Northern Hemisphere vaccine is identical to that used in Australia, it is possible that we will experience low vaccine effectiveness against influenza A (H3N2) viruses and a relatively severe influenza season if they predominate.
The centers' disease monitoring statistics showed a total of 53,815 reported cases of flu-like illness last week, including eight people with serious flu complications, six of whom had not received flu vaccinations.
Goudreau says "the relatively low percentage of effectiveness in Australia is due to many factors, including the shifting and changing of the flu virus each season".
Goudreau agrees with the authors' suggestion that research should continue to develop a better and more effective universal flu vaccine created to decrease illness and death.
