This mod adds separate vaccines for the flu, malaria, plague and sleeping sickness.
The vaccines are probably OP for the game but vaccines are kind of OP in real life. The plague, malaria and sleeping sickness vaccines are all effective for about 20 years. The flu vaccine is effective for about one year. I tried to make the requirements for making the vaccines high to somewhat counter the OP-ness of them. They also must be kept frozen or they will spoil in one day.
Each vaccine must be researched separately and then they can be crafted at the drug lab.
This is my first mod so I probably messed up some parts of it. Please tell me if you find something wrong with it.
Per request I tried making a vaccine for the other diseases like gut worms and blood rot but I wasn't able to. This mod makes the colonists have immunity to the diseases before they catch them instead of having to gain immunity before the disease wins. Colonists don't build immunity to the other diseases, they just have to wait it out, so I do not know how to make them immune to the other diseases.
