According to Buckingham Palace, Queen Elizabeth II tested positive for COVID-19 on Sunday and is suffering mild, cold-like symptoms.
The 95-year-old British queen will continue to do limited responsibilities at Windsor Castle this week, according to the palace.
In a statement, the palace added, “She will continue to receive medical treatment and will follow all proper guidelines.”
The coronavirus vaccination was given to the queen three times.
COVID-19 has lately infected both her eldest son Prince Charles and her daughter-in-law Camilla, Duchess of Cornwall. Since then, Charles has returned to work.
On Feb. 6, the queen, Britain’s longest-reigning monarch, celebrated her 70th year on the throne.
