As countries around the world prepare to vaccinate people against the coronavirus, tech companies are rushing to demonstrate their willingness to help fight the deadly virus. China’s ride-hailing leader Didi Chuxing is pledging a $10 million fund to support COVID-19 vaccination efforts in 13 markets outside its home country China, the company said on Friday. The multi-purpose fund will be used to reduce fees for passengers going to vaccination appointments and frontline healthcare workers traveling to vaccination locations.
