A retired British shop clerk received the first shot in the country’s COVID-19 vaccination program Tuesday, signaling the start of a global immunization effort intended to offer a route out of a pandemic that has killed 1.5 million.

The Berkshire Eagle reports Margaret Keenan, who turns 91 next week, got the shot at 6:31 a.m. on what public health officials have dubbed “V-Day.” She was first in line at University Hospital Coventry, one of several hospitals around the country that are handling the initial phase of the United Kingdom’s program. As luck would have it, the second injection went to a man named William Shakespeare, an 81-year-old who hails from Warwickshire, the county where the bard was born.

“I feel so privileged to be the first person vaccinated against COVID-19,” said Keenan, who wore a surgical mask and a blue Merry Christmas T-shirt decorated with a cartoon penguin wearing a Santa hat. “It’s the best early birthday present I could wish for because it means I can finally look forward to spending time with my family and friends in the New Year after being on my own for most of the year.”
