What is the combination for making Vaccine in Doodle God?

To create a Vaccine in Doodle God, you need to combine two specific elements: Bacteria and Medicine. HereÔÇÖs how you can achieve this step by step. First, you need to unlock the Bacteria element. Bacteria can be created by combining Swamp and Life. Swamp is made by combining Earth and Water, while Life is created by combining Energy and Swamp. Once you have Bacteria, you need to unlock Medicine. Medicine is created by combining Human and Grass. Human is made by combining Life and Clay, and Grass is created by combining Earth and Plant. Plant is made by combining Life and Swamp. Once you have both Bacteria and Medicine, combine them to create the Vaccine. This combination follows a logical progression, as vaccines are typically developed using bacteria or viruses and medical treatments. Experimenting with these combinations will help you progress further in the game and unlock more advanced elements.
