In fact, when they looked at influences on the day of vaccination itself, mood was found to have an even greater impact - accounting for between 8% and 14% of the variability in antibody levels. For adults, vaccination rates increased about 1 percent, from 46 percent in 2015-2016 to 47 percent in 2016-2017.

The group recommended a new influenza A H3N2 strain, and swapped out the Victoria-lineage B strain with a Yamagata-lineage virus that had been recommended past year as the second B strain in quadrivalent vaccine formulations.

In a new study, European scientists found evidence that being in a positive mood on the day of a flu vaccination can increase its protective effect. Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. That's because data for the US shows sprays aren't as reliable as vaccines administered with needles (sorry, kids).

The investigative team measured negative mood, positive mood, physical activity, diet and sleep three times a week over a 6-week period in a group of 138 older people due to have their flu shot.

Flu viruses are constantly changing, thus the flu strains in the vaccine is reviewed each year and updated as needed based on which flu viruses are circulating, making people sick, and how well the flu strains in the previous season's vaccine protects against those viruses.

For this year's flu season, about 166 million doses of vaccine will be available, Price said.

The hospitalization rate last season for influenza was almost double that of the 2015-2016 season, officials said. "This is particularly true for certain groups: older adults, pregnant women, people with some long-term medical conditions and young children", he explained.

Although the vaccination rate among health care workers seems high, it ranged from 92 percent of those who worked in hospitals, to 68 percent of those working in nursing homes and to 76 percent in clinics. The study examined data from four flu seasons between 2010 and 2014.

"This is the first year that pharmacists across Australia have been able to administer flu vaccinations in community pharmacies and a survey of patients earlier in the year suggested showed more than seven million Australians aged 18 to 64 years were planning to have a flu shot this year", says the Guild newsletter. "Influenza is an unpredictable infectious disease".

Although not a substitute for getting an annual flu vaccine, health officials also stressed the importance of everyday preventive actions to decrease the spread of flu and the appropriate use of influenza antiviral drugs to treat influenza as part of the CDC "Take 3" approach to fight the flu.

Flu season is fast approaching, and USA health officials are anxious that this season could be a bad one.
