The virus is able to 5) __________ rapidly to avoid 6) __________ by the immune system, and is also covered in sugary molecules which block access by antibodies. 7) __________, certain parts of the virus must remain 8) __________ unchanged so that it can catch hold of and enter human cells. One protein that sticks out from the surface of the virus and binds to receptors on host cells is one such region, which makes it a target for vaccine development.
Previous analyses of the 9) __________ of people that have been able to keep HIV from developing into AIDS for long periods of time 10) __________ revealed a 11) __________ group of antibodies - including b12 - that seem to fight HIV with some degree of 12) __________.
