SisPro is a system created for a B2B vaccination company. It was used to deliver 100k shots of influenza vaccine in 2025, in over 200 companies across Brazil.

This company sells vaccination campaigns to other businesses in Brazil, mostly multinationals (Volkswagen, Saint-Gobain, Mondelez…)

The admin platform is built on Bubble, used to track the different vaccination campaigns, clients, surveys, and other aspects.

There are multiple types of users in the platform: Procat, which is the responsible company, with its admins and team members; the customers (other companies), with also admin members and team members; and the people that can buy vaccines for themselves and their families, that can make the purchases self-service.

It also has a mobile platform for the nurses, built in Flutterflow, so they can mark the vaccinations as completed, and the system updates the admin platform in realtime. The reason it was needed to be built in Flutterflow was due to having to be used offline.

Some of these companies opt for conducting surveys on their employee base to see if they will have the vaccination, we had over 12k respondents.
