Prince William sets royal fan's pulses racing with new picture

This week, Prince William received his first Covid-19 vaccine ... but despite the serious nature of the vaccination, it wasn't him getting the injection that people couldn't stop talking about. 

Taking to social media, the Duke of Cambridge shared a picture of himself being administered the vaccine.

Alongside the image, he wrote: "On Tuesday I received my first dose of the COVID-19 vaccine. To all those working on the vaccine rollout - thank you for everything you’ve done and continue to do."

In the picture, the father-of-three can be seen lifting the arm of his jumper up in order receive the vaccination – and at the same time showing off a very toned arm.

Royal fans were quick to comment on the 38-year-old's impressive bicep, with many labelling him a "hottie."

William joined his father, Prince Charles, as well as his grandmother, Queen Elizabeth II, in having the Covid-19 vaccine.

His grandparents, the Queen and the late Prince Philip, received their first vaccinations in January. Charles and stepmother Camilla, Duchess of Cornwall, had theirs in February.
