Universal Flu Vaccine

Question 1

Antigenetic shift

Answer 1

Sudden changes of the surface antigens of a virus leading to very different recognition sites

Question 2

Immunisation

Answer 2

Introduction of a dead or deactivated form of a virus to encourage the production of antibodies by the immune system to protect against actual infection

Question 3

Hemaglutinin

Answer 3

A flu virus glycoprotein that binds to the host cell

Question 4

Neuraminidase

Answer 4

An enzyme which helps the virus to breach cell walls

Question 5

Antigenetic drift

Answer 5

Small changes in the gene of a virus that happen over time as the virus replicates, creating viruses that are slightly different to each other

Question 6

Team 1

Answer 6

Applied mutations that realigned the subunits of the stem at the top, this allowed for a functional structure for the vaccine

Question 7

Team 2

Answer 7

Pulled the subunits of the protein together by binding a bacteria-derived mani particle to the stem
