Just 4.66 million COVID-19 vaccines have been administered across the US in the last three weeks despite federal officials having distributed 15.4 million doses to the states. It means more than two-thirds of the vaccines shipped within the US have gone unused and just 1.4 percent of the population has been vaccinated as cases, deaths and hospitalizations continue to surge across the US. Surgeon General Jerome Adams on Tuesday admitted that the largest vaccination campaign in US history, which has been in the works for months amid the pandemic, has been a 'little bit messy'. He called on governors across the country to speed up the process by moving to the next priority groups if demand wasn't being met. California Gov Gavin Newsom said on Monday that his state has only vaccinated 1 percent of the population. The governors of New York and Florida have vowed to penalize hospitals that fail to dispense shots quickly.
