Prince Edward says Prince Philip is "a lot better".
Dr. Emily Lawson, who leads the effort on behalf of the National Health Service (NHS) England, told the Queen how healthcare workers, government officials, volunteers and the Armed Forces have worked together across all four nations to deliver the vaccine to every community in the United Kingdom. "It was very quick, and I've had lots of letters from people who have been very surprised at how easy it was to get the vaccine", Elizabeth added.
The monarch said she understood getting a jab could be a "difficult" experience for some people but urged everyone to "think about other people rather than themselves".
She added: "I think it is remarkable how quickly the whole thing has been done and so many people have had the vaccine already".
The 94-year-old is mourning the deaths of her close friend Lord Samuel Vestey and first cousin Lady Mary Colman and is likely to be anxious for her husband Prince Philip, who has been in hospital for nine days, fighting an infection.
St John Ambulance said it was "delighted" to welcome the countess to its team of more than 10,000 trained volunteers in vaccine centres across England.
The head of state chuckled as she replied: "Well, as far as I can make out it was quite harmless".

This week's video call marked the first time Queen Elizabeth has discussed the issue of the COVID-19 vaccination publicly.
They estimate that around 15 per cent of the population will not take up the offer of a jab, with scepticism highest among the young and minority ethnic groups.
The Queen spoke with four health officials over Zoom.
After the call Dr Lawson described the Queen's comments about her vaccine experience as an "incredibly important vote of confidence in the programme". They are reminiscent of her decision in 1957, to let it be known that Prince Charles and Princess Anne had been given the polio vaccine in order to counter public fears.
On December 8, Britain became the world's first country to begin a mass vaccination drive against the coronavirus.
Meanwhile, the Queen is yet to visit her husband in hospital.
It comes days after the Palace confirmed Philip was "responding" to treatment.
It is understood it is a non-coronavirus health matter.
Other members of the royal family, including heir-to-the-throne Prince Charles and his son Prince William, have been visiting vaccination centres over the last fortnight to thank staff and volunteers for their work. The UK now ranks fifth in the world for having the highest COVID-19 case count and death toll, according to Worldometer.
The Queen called the disease a "plague".
A senior royal source said: 'It is a passionately held belief that people need to get out there [and get vaccinated] - this is important'.
