As the first doses of the COVID-19 vaccine began rolling out Monday, healthcare experts warn to not allow the vaccine’s arrival to create a false sense of security especially during the holidays. Dr. Sudha Nagalingam, the Medical Director of El Rio’s HIV Infectious Disease Clinic, said Arizona’s recent spike in cases likely tracks back to Thanksgiving when people loosened restrictions and met with family and friends.

The initial rollout of Pfizer’s COVID-19 vaccine has begun, and vaccines are shipping across the U.S. Demand for COVID-19 vaccines will outpace supply for the foreseeable future. Yet experts have warned that a substantial proportion of these highly perishable vaccines could go to waste if they are not being used before they expire.

Countless people across the country are desperate to get their hands on the coronavirus vaccine. But the same could be said for another icy treat with some surprising similarities: Dippin’ Dots. Invented by a microbiologist in 1988, Dippin’ Dots’ self-proclaimed “Ice Cream of the Future” maintains its characteristic beaded form only if stored at -49 degrees Fahrenheit. Slipping even a few degrees in the wrong direction can jeopardize the quality of a batch.

When the first doses of Pfizer's (PFE) coronavirus vaccine were packed with dry ice in Michigan and shipped across the U.S. this weekend, it set into motion a sprawling distribution infrastructure that will face its biggest test in modern history — and highlighted some surprising vaccine stock plays.

t's one of the biggest logistical challenges in modern history: How will millions of Covid-19 vaccine doses that must be kept at incredibly cold temperatures be quickly shipped across continents and oceans? One company is using its experience with tuna as a guide. Thermo King — which revolutionized the transportation of food through advances in temperature-controlled shipping before World War II — is working with pharmaceutical companies, governments and logistics firms to ensure vaccines are preserved as they travel to clinics and hospitals. To make this happen, they've reworked containers typically used to transport fresh tuna to Japan, which requires similar frigid conditions.
