Protect yourself from the flu

"Be sure to get your flu shot early because it can take up to two weeks to take effect".

In contrast, all of the mice that were given traditional flu shots got sick and died when exposed to the same lethal doses of flu. The 2016-2017 seasonal flu vaccine was updated to include the new version of this protein; however, Hensley's lab found that the egg-grown version of this protein acquired a new mutation.

After vaccinating the mice, the researchers infected them with nine strains of the flu - including strains of H1N1, H3N1, H3N2 and H5N1- at a dose that typically kills mice.

Vaccine producers have made flu shots with eggs for decades, but a new study says the manufacturing process curbed the efficacy of last year's shot and warns that the problem could repeat this year.

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.


The Centers for Disease Control and Prevention (CDC) estimates that previous year influenza vaccination prevented approximately 5.1 million influenza illnesses, 2.5 million influenza-associated medical visits and 71,000 influenza-associated hospitalizations.

A group of researchers at the Nebraska Center for Virology may have succeeded in developing a flu vaccine that would provide lifelong protection against the pesky winter bug.

The goal is to combine the desired HA and NA antigens from the target strain (flu strain 1) with genes from a harmless strain that grows well in an egg (flu strain 2). A unit of Australia's CSL, the company is using a massive former Novartis plant in North Carolina for its cell-based flu vaccine production. For example they may have got a food vaccine and got sick anyway.

It's best to get vaccinated before flu viruses start to spread in your community. These statistics demonstrate "that there is a need for more effective vaccine technologies", Weaver argues.

Flu vaccines aim to protect us by priming our immune systems.
