The Queen and the Duke of Edinburgh have received their COVID-19 vaccinations, Buckingham Palace has said.
A royal source confirmed the injections were administered at Windsor Castle by a household doctor.
It is understood the Queen decided the information should be made public to stop further speculation and prevent inaccuracies.
Buckingham Palace rarely comments on the private health matters of the 94-year-old monarch and Prince Phillip, 99.
The pair have been spending the lockdown shielding at Windsor Castle, following their decision to forgo the Royal Family gathering at Sandringham and have a quiet Christmas.
So far, more than a million people have been given the jab.
Last month, Chelsea Pensioners thanked the NHS for an "early Christmas gift" as they were vaccinated against COVID-19.
Veterans in Warwickshire have also been vaccinated against coronavirus after 50 residents of a care home in Solihull, with some from a military background, received the jab.
Earlier this week, the Defence Secretary Ben Wallace told Forces News that he expects the military to be "doing injections" by February, with 111 personnel already involved in the planning.
Three coronavirus vaccines have now been approved for use in the UK, with the jab from US biotech firm Moderna being approved, joining the vaccines from Pfizer/BionTech and Oxford/AstraZeneca.
