No Vaccine is written on a sign at the Lincoln Park Covid-19 vaccination site on February 19, 2021 in Los Angeles, California where more than 12,000 vaccine appointments have been delayed due to weather-related shipping delays of the vaccines. – At least two major shipments totalling more than 60,000 doses are being held up in other states amid icy roads and grounded flights from a massive winter storm affecting large portions of the country.
