Winter Storm Uri Throws US Vaccine Rollout Into Chaos

The massive sprawl of winter storm Uri put COVID-19 vaccinations on hold in nearly half of US states this week.  
At least 22 had to delay or cancel vaccination appointments, Oregon health officials are quietly shuttling doses from storage facility to another and Kentucky paired each COVID-19 vaccine storage site with a generator. 
And Harris County, Texas, ran into the nightmare scenario: the power went out at a hospital storing some 8,000 doses of Moderna’s vaccine. 
Doses had to be quickly redistributed to nearby hospitals, universities and a prison before they spoiled. 
Most of the precious shots were salvaged, but neither the storm nor the power outages are over for Texas and other states – and officials don’t even know how long the outages will continue. 
With another storm rolling across the country hot on Uri’s heels, the weather threatens to ruin precious doses of vaccine and delay the rollout intended to finally bring the pandemic to an end.
