Spring is here, and with it comes pollen allergies. This ad for Apoteket, the Swedish pharmacy chain, reflects just how miserable you can feel with hay fever by imagining an outbreak as a zombie apocalypse. In the spot, by Forsman & Bodenfors, people stumble around like zombies in a city with red eyes and pained expressions, causing chaos and destruction in the well-known style of a zombie horror flick. The ad was made following predictions that the pollen season in Sweden is predicted to be the worst one since records started 45 years ago.
