What happens in a population if no one is vaccinated?

What if we are all vaccinated?

Vaczine can answer those questions without having to experience it firsthand, and in just a few minutes.

Why does Vaczine exist?

This program was created for educational purposes in order to illustrate the effect of vaccination in the prevention of infectious contagious diseases at the population level.

How does it work?

Vaczine works under the following rules:

1) The program creates a population of people that includes infants, children, youth, adults, and the elderly.
2) Each person moves freely on the screen interacting with the others.
3) Each person can be in five different states: healthy without vaccination, healthy vaccinated, sick, cured and dead.
4) A sick person can infect another (not immunized) by contact.
5) Vaccinated people are immune to contagion.
6) After a while, sick people are cured or die.
7) People who are cured are also immune to disease.
8) Parameters such as percentage of vaccinated people (coverage), infectivity and mortality of the disease can be configured. Before each simulation.

This program is based on the engine of a previous program called Evoluzion® which is a genetics and evolution simulator.
