Vaccines like to be kept cool, none more so than the Pfizer candidate for Covid-19, which has to be deep-frozen. And that's going to be an issue for developing countries -- and for rural areas in the developed world. The "cold chain" is just one of the challenges in distributing vaccines worldwide. There are plenty of others: decisions about priority populations and databases to keep track of who's received what vaccine, where and when. Additionally, different vaccines may have more or less efficacy with different population groups; and governments will need PR campaigns to persuade people that vaccines are safe.

We are nine months into the covid-19 pandemic, with many succumbing to face covering and physical distancing fatigue, and pockets of pervasive skepticism about the virus threat and its risk.

A Food and Drug Administration advisory committee was meeting Thursday to discuss whether the agency should grant emergency use authorization for Pfizer Inc.'s coronavirus vaccine candidate.

The nation’s first COVID-19 vaccine stands on the verge of approval, yet the complex distribution of the product — and the risk along the way — is keeping some logistics and public health professionals up at night. The stakes could not be higher. This vaccine represents what one freight industry executive has termed “the biggest product launch in history.” Within 24 hours of emergency authorization from the Food and Drug Administration, the vaccine maker Pfizer plans to move the product to patients nationwide.
