Pharma advertising has made viruses feel predictable: CGI blobs, glowing throats, and AI-generated animations that blur together across the category.
But a sore throat feels more personal than that. It creeps into your day, stays with you, and becomes impossible to ignore.
Bactidol needed to make that early throat threat feel just as present, while helping the brand stand out in a category full of generic digital visuals

This is Kasabayrus (Viruses that tag along with you), a cast of 100% handmade virus mascots brought to life through practical effects.
Designed from scratch and built as foam suits, the viruses were performed by actors who followed our protagonist everywhere in our online film, turning a common symptom into a constant, visible presence.

As a spin-off of Kasabayrus, another film was developed for people who frequently experience sore throats from excessive talking, particularly those whose jobs require them to speak all day. We brought to life the burden of dealing with a sore throat when the day is far from over.
