Is there any evidence that vitamin B12 is helpful for prevention of mosquito bites?

I've heard lots of times that vitamin B12 (or indeed garlic) is helpful for the prevention of malaria, but as I understand it, this isn't true. I'm trying to get a definitive answer. Is there any evidence that this does help reduce the chance of getting a mosquito bite?

How does a patent Foramen Ovale increase the risk of stroke?

I heard yesterday that a patent Foramen Ovale (PFO) increases the risk of stroke - why would it? Is it that the turbulence from the PFO or possible damage on the endocardium causes small emboli to come off from here or is it that clots pass through the PFO. Also, I hadn't heard this before so is it actually true and / or a risk factor. Any help would be great.
