Zombies have always been popular, but with the smash hit The Walking Dead on the air they’re even more popular. Now a company called Titlfactor is using their zombie game, ZombiePox, to help figure out better ways to education people about vaccinations. The game revolves around making sure the right people in the population to stem the spread of the zombie infection.

The game is a rethemeing off Pox, a game originally developed to help inform the public about the misinformation about vaccines. They’ve found that high schoolers were more interested, and retained more information off the zombie version of the game, which is pretty awesome. Followup studies are being done to further understand data originally collected.
