Resident Evil 3 vaccine puzzle: find the antigen and adjutant samples
In order to make the Resident Evil 3 vaccine at all you'll need to find two different samples and mix them together, an antigen and adjuvant.
You find the antigen sample in the 2F lab:
To get it look for a row of three yellow robot arms in glass cabinets and interact with the console in the middle. One of the arms should then fetch the sample for you.
The adjuvant sample lives in the 2F Incubation Lab:
The sample will be in a cabinet of glass fronted draws with one green light in a line of red ones. Interact with the draw to get the sample
Resident Evil 3 vaccine puzzle temperature solution
Once you've combined the antigen and adjuvant sample insert them in to the macine you'll find in the main 2F room, here:
You'll then need to set three different temperature controls between low, mid and high so that all three are green. The solution for that is as show below: Mid - High - Low.
Once that's done the vaccine will be mixed and you'll be able to continue on with saving Raccoon City. Well trying at least. We all know how this ends.
