Prince Philip, the 99-year-old husband to Queen Elizabeth II, was admitted to the hospital Tuesday evening after feeling unwell, Buckingham Palace confirmed Wednesday.
The palace called his admittance to London’s King Edward VII Hospital a precautionary measure and noted he is expected to remain in the hospital for a few days of observation and rest.
The Duke of Edinburgh, the oldest and longest-serving royal consort in British history, celebrated his 99th birthday in June without much of a fuss at Windsor Castle, where both he and the queen have been self-isolating since mid-March amid the coronavirus pandemic.
Queen Elizabeth, 94, and Philip have received their COVID-19 vaccinations, the palace said last month.
The queen wanted to go public with news of their vaccinations to dispel further speculation or inaccuracies about whether they received it. A household doctor at Windsor Castle administered the vaccines.
The royal couple has been married since 1947. Philip is the longest-serving royal consort in British history. He and the queen have four children, eight grandchildren and nine great-grandchildren.
He was born June 10, 1921, on the Greek island of Corfu, son of a prince of the Greek and Danish royal families. A former naval officer and keen polo player, Philip enjoyed robust health well into old age but has had a number of health issues in recent years.
In 2011, he was rushed to a hospital by helicopter after suffering chest pains and treated for a blocked coronary artery. In 2017, he spent two nights in the King Edward VII hospital and was hospitalized for 10 days in 2018 for a hip replacement.

Philip was last hospitalized in December 2019, spending four nights in the King Edward VII Hospital for what the palace said was planned treatment of a pre-existing condition.
He was forced to give up driving at the age of 97, after smashing into a car while driving a Land Rover near Sandringham estate in January 2019. Philip needed help to get out of the Land Rover but wasn’t injured. A woman in the other vehicle suffered a broken wrist.
Philip has carried out thousands of public engagements over the decades, until he retired from public life in 2017. Until the pandemic struck, he had been living at Wood Farm, a modest cottage on the edge of Sandringham, the sprawling royal estate in Norfolk where the royal family typically spends Christmas holidays.
