Do you mean the question that said 'describe how a vaccine causes the production of antibodies?'

I just put that vaccines contain antigens, which stimulate helper T cells which stimulate B cells to divide by clonal selection into plasma cells. Plasma cells produce many antibodies rapidly

i thought it said how does giving a vaccine make some one immune not production of antibodys

No it definitely was in relation to the production of antibodies rather than becoming immune, but i'm sure that if you wrote about how someone becomes immune you will have mentioned the same points just a bit extra then required

Sorry I only have the AS but if you visit their website: Tailored Tutors I think you will be able to get A2 resources but you have to pay for it.

Does anyone have the actual question papers and mark schemes for set 2 specimen papers? My teacher hasn't given me access to them :frown:

Nah I specifically remember the word antibodies! I remember writing about the Plasma cells producing them... Writing about someone becoming immune would probably get you the marks though as that entails the production of antibodies!
