The exam!

[Gazillionaire]

For the virus question, i wrote that there was a new strand of the bacteria so the antibodies didnt recognise the shape of the new antigen so an immune response couldnt be triggered. is this correct?

Is it possible to get an above 40 SS with a high A on the first exam?

I wrote that by adulthood, the memory cells may have started to decline and therefore adults started getting affected.

I then said a possible fix is to have vaccinations in adulthood to produce more memory cells.

pretty much the same as me, but the mutation sounds more correct.. haha

[InsaneMcFries]

Why would they specifically refer to the adults? I'd assume if they were giving vaccines to children for a mutated bacterium that they would inform the damn adults about the mutation? :S

[MagicGecko]

hahaha yeah i wrote that the active site or something along those lines of the bacteria must have mutated, therefore the adults that had been vaccinated when they were little were vaccinated for the old bacteria. i guess this would also explain why the questions asked specifically for adults since the children would be vaccinated with the new one already.
.......argggg im not sure anymore!!!!!!!!!! (><)

this does sound good, maybe a question they might take 2 answers for?

Both of them are valid and Reasonable answers, any of them will get the marks.

[G-lain]

There were multiple answers, I'm assuming as long as you justify your answer then it's all good.
Off the top of my head, a few explanations could have been.

• The immigration of a large population which hasn't been vaccinated against the bacteria
• The bacteria mutating resulting in antibodies that no longer match the antigen
• Memory cells expiring, resulting in adults losing their immunity

I think out of those only 2 and 3 would of been accepted.

[InsaneMcFries]

Holy crap! Immigration is a pretty cool idea but it is so unlikely.

[G-lain]

Yeah I doubt anyone would have written that, but I'm not sure if they could really argue against it if someone did choose to write it.

There was a question which was something along the lines of "What steps would you take if someone who wasn't vaccinated against a certain disease returned to their country after visiting a disease-ridden country"

I wonder if it's okay if I wrote "Test his blood for pathogens, if it's positive, kill him and then burn his corpse".

Yes it was the 4 month old baby.
