Vaccine infrastructure

Pharmacies like CVS and Walgreens have to consider storage requirements, more staffing and store layout for vaccine distribution.

Employer-sponsored programs make vaccinations convenient and help to normalize the idea of getting one.

The list includes funding, a plan for communicating with the public, medical personnel training and storage capabilities.

That would be an advantage particularly for getting a COVID-19 vaccine to developing countries.

"There will be consequences, always, from these choices," says former WHO chair David Salisbury. "But we try to make them with the best interests of the most people at heart."

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.
