To get the flu shot or to not get the flu shot...The yearly dilemma of whether to inoculate yourself against (what scientists think might be) the annual flu strain is about to surface soon enough. But according to new research, finding out if you’re at higher risk of having an adverse reaction to the flu could be determined by a genetic test.


About one in 400 people carries a variant of a gene called IFITM3, which causes them to have more severe cases of the flu virus because the variant is unable to encode a protein that helps the body resist viral infection. The benefit of a genetic test is that if there is a patient with IFITM3 “You can then start to stratify people ahead of time and prioritize them for vaccination,” said Paul Kellam, an expert in virus genomics at the Wellcome Trust Sanger Institute.

Regardless of what you decide to do, some preventative methods include increasing your intake of vitamin C, zinc and Echinacea as well as ensuring you’re getting seven to nine hours of sleep daily. In what ways do you protect yourself against the virus?
