A vaccine is a substance of already killed or neutralised pathogens which are entered into the Blood stream and are used, to our immune system, as "Targets" or "Practice". Vaccinations are a great start to get our immune system active for when we actually catch the disease, Our white bloood cells will know exactly what to do when confronting a real pathogen because of when they fought off the already dead or neutralised pathogens via a vaccination we took a few days before the attack.
