The ineffectiveness of this year's current flu vaccine was evident when Australia, whose flu season runs from May through October, resulted in more than two-and-a-half times the number of laboratory confirmed notifications of influenza reported to the National Notifiable Diseases Surveillance System (NNDSS) this year when compared with the same period last year.
Another illness that some people may not know isn't related to the influenza virus is the stomach flu.
Although the flu vaccine is not ideal and some people who get vaccinated may still get the flu, it's possible that the vaccination may make symptoms milder. However, Weaver said his study is the first to report the use of multiple centralized HA genes, identified using protein sequence analysis programs, to provide the greatest level of cross-protective immunity possible.
The more people that are immunized, the harder it is for flu to circulate in the community, the department stated in its release.
A new flu vaccine that can protect against many different strains of the flu shows promise in early animal tests, according to a study. "The 2017 vaccine that people are getting now has the same H3N2 strain as the 2016 vaccine", noted Scott Hensley, Ph.D., an associate professor of microbiology at the Perelman School of Medicine at the University of Pennsylvania. You need a flu vaccination every year for two reasons.
Excuse #2: I'm scared of needles. Flu shots can not give you flu illness.
Influenza is a highly contagious respiratory virus that can cause fever, cough, muscle aches and fatigue. At some point during the development of last year's vaccine, the egg-grown protein acquired a mutation that reduced its effectiveness in warding off the live virus.
Excuse #4: I hear the flu vaccine can be risky for children. Any flu infection can carry a risk of serious complications, hospitalization, or death, even among otherwise healthy children and adults. The flu shot is available at the flu clinics, physicians' offices, as well as at pharmacies.
Seqirus, the second-largest flu vaccine company, over the summer touted its industry-leading capacity for large-scale production of cell-based shots.
