To build public trust, Pfizer shared details of their trials: who was tested, the race and ethnicity of participants, how they were monitored, how to measure success and funding sources.

One immunization expert says the Biden team should be talking to state leaders about what they'll need to roll out vaccines.

Markets were already sharply higher when Pfizer said that data shows vaccine shots may be 90% effective at preventing COVID-19.

The manufacturing can't happen until suppliers know exactly which vaccine candidates they're working with.

The retailer plans to hire 15,000 additional staff, mostly pharmacy technicians.

Katja Busch says efficient vaccine distribution is most dependent on coordinated efforts between the involved parties.

Health departments will need trained personnel and equipment like syringes and vials. And states want special funding.

Julian Sutch, head of Emirates SkyCargo's pharmaceutical division, believes carriers like his are up to the task of global vaccine distribution, but acknowledge there are plenty of challenges to overcome.
