Gap: Pfizer has been using data science and machine learning to streamline clinical trials, supply chain and manufacturing, and drug development. However, there is a lack of focus on the accessibility and affordability of their medicines for low-income countries and marginalized communities.

Solution: Pfizer can collaborate with non-profit organizations and governments to provide affordable and accessible medicines to low-income countries and marginalized communities. They can also invest in research and development of medicines for neglected diseases that affect these communities. Additionally, they can implement transparent pricing strategies and reduce the cost of their medicines to make them more accessible.

Summary: While Pfizer has been using data science and machine learning to improve their operations, there is a need to address the accessibility and affordability of their medicines for low-income countries and marginalized communities. Collaborating with non-profit organizations and governments, investing in research and development of medicines for neglected diseases, and implementing transparent pricing strategies can help address this gap.
