The US vaccination program aims to reach 100 million people by April.
New York nurse Sandra Lindsay was among the first in the country to receive a coronavirus vaccine when the Pfizer rollout began.
Footage of her being vaccinated was streamed on the Twitter feed of New York Governor Andrew Cuomo, whose state was the epicenter of the US epidemic in the first wave earlier this year.
Lindsay said, “I hope this marks the beginning of the end of a very painful time in our history. I want to instill public confidence that the vaccine is safe. We’re in a pandemic and so we all need to do our part.”
Centers for Disease Control and Prevention guidelines submitted to US states say healthcare workers should be prioritized first, as well Americans living in long-term care homes.
Essential workers are expected to be next in line for the jab, but it will be up to states to decide which industries to prioritize. The young and healthy are said to be at the back of the queue.
