Oliver had practically moved into his potions lab at Hogwarts and had gotten very little sleep since he had started to recover from the illness, which he had just earlier that day learned was a modified form of dragon pox.
He took the parchment from the squawking owl - clearly irate from having to fly all the way into the dungeons. He didn't know much about Goldstein and was wary of trusting anyone new these days. Still, Goldstein was right - the fastest way to a vaccine was working together.

Yes, this is amenable. You say you didn't fall ill, eh? A good place to begin is with a sample of your blood to compare it to my own. Also, if you could procure a sample of blood of someone who has yet to build up antibodies to the virus, that would also help. I trust you can procure that.
