From: "Towards a universal flu vaccine" Each year, the flu vaccine includes antigens from two strains of Influenza A and two strains of Influenza B. These antigens are from the head of the H spikes an area that sticks out from the virus and so, is very easy for human immune cells to detect. However, the problem with using the head of the H spike as an antigen is... O The H spike head mutates very rapidly, so quickly changes to forms not recognized by human immune cells. O The H spike head is exposed on the surface of the virus for only a short period of time. Viruses quickly pull the H spikes back inside the virus, shiclding them from human immune cells. O The H spike head is often too big for the human immune cells to attack. O The H spike head is often too small for the human immune cells to bind to.
