Stuck in Cisterns Control Room

[JimmyVolatile]

I am up to the Morgue and found a copper tube. Where's the vaccine?

Combine the copper tube with the hollow needle to form an extraction device. Drill a hole in the skull of the day-old corpse on the table and the put the copper tube inside. Finally, vaccinate yourself with the blood that pours out of the hollow needle by impaling yourself on it. Loooovely..
