The flu shot is available at the flu clinics, physicians' offices, as well as at pharmacies.

Meanwhile, 69 per cent of health-care workers in 28 public long-term care facilities in the region got flu shots during the same time. The conventional influenza vaccine platform uses weakened or dead versions of the influenza virus to stimulate immunity against hemagglutinin (HA), a spike-shaped protein that extends from the surface of the virus and attacks cells.

Flu vaccines that are recommended for this season are either made with inactivated (killed) flu viruses or without flu viruses at all.

Colorado entered Sunday 8-5-0 after finishing with just 48 points last season, the fewest by a non-expansion team since 1998-99. Girard, 19, was a 2016 second round pick of the Predators and made his National Hockey League debut this season.

Current vaccines provide protection against only three or four strains of the flu and are not always correct in predicting what strains will be worst that year. They are antigenically similar to the strain of vaccine. Some people have a presumption that the flu vaccines is not effective. Those that received higher doses of the vaccine didn't even get sick.

"Our experiments suggest that antigens of the influenza virus grown in systems other than eggs are probably more likely to trigger an immune response by producing neutralizing antibodies to the H3N2 viruses in circulation", said professor Hensley. The mice protected with the new vaccine survived exposure to "lethal doses of seven of nine widely divergent influenza viruses".

The vaccine is different each year because the virus changes frequently - so it's important to get it every fall. "During the 2014-2015 influenza season, clade 3C.2a H3N2 viruses possessing a new predicted glycosylation site in antigenic site B of HA emerged, and these viruses remain prevalent today", wrote the article's authors. The vaccine is made from an inactivated virus that can not transmit infection.

An FDA laboratory worker injects an influenza virus into an egg, where it will grow before being harvested-one of the many complex steps involved in creating a traditional flu vaccine. "Our data suggest that we should invest in new technologies to significantly increase the production of influenza vaccines that do not depend on eggs", he argued.
