Dasa, Brazil’s leading diagnostics company, launched an e-commerce platform to sell vaccines during the COVID-19 pandemic. A key differentiator: nurses would deliver and administer vaccines at the customer’s home.

The challenge

How can we optimize this unconventional e-commerce experience and support Dasa’s goal of becoming Brazil’s leading online vaccine provider?

• Analyzed user behavior to inform prioritization of improvements.

 

Key Outcomes
