No, Antiserum Injectors are not mandatory. Not bringing them causes your Armor to degrade when outside of the vaporizer bubbles, which essentially means you take more damage (again, outside of the bubbles) - but with a good squad you can keep each vaporizer console at 100% efficiency, which means their bubbles almost overlap.

Actually getting the Nidus pieces can be a bit time-consuming (I was grinding this mission with friends pretty much all day yesterday), as there is no way to guarantee Rotation C drops. What I recommend is keeping an eye on the rewards table - if you receive a reward from Rotation A, keep going and you should get a B next (or another A then B), then a C. This means you may have to get four rewards before you can get a Nidus piece; plus there is a chance that he won't drop on Rotation C at all.
