[ Smart thinking, he thinks but doesn't say. ]

In hypothetical world where I did have samples, I would not inject anyone to begin with. The decima virus needs to be carefully treated, with regular check-ups to maintain stability. I would not just jab someone and watch what happens—completely irresponsible.

So considering that there is very little chance I would be able to run those tests and check-ups in first place, you have nothing to worry about.
