Queen and Duke of Edinburgh receive coronavirus vaccinations
In an unusual move Buckingham Palace, which rarely comments on the private health matters of the monarch and duke, announced that the 94-year-old head of state and her consort, 99, had been given the injection.
It is understood that the Queen had decided the information should be made public in order to prevent inaccuracies and further speculation.
A Buckingham Palace spokesman said: "The Queen and the Duke of Edinburgh have today received Covid-19 vaccinations."
A royal source confirmed that the injections were administered by a royal household doctor at Windsor Castle.
The Queen and Philip have been spending the lockdown in England sheltering at their Windsor Castle home after deciding to have a quiet Christmas at their Berkshire residence, and forgo the traditional royal family gathering at Sandringham.
