The Prince of Wales has praised staff at slotxo a vaccine factory for their part in the battle against Covid-19. Prince Charles and the Duchess of Cornwall visited the Wrexham plant at the start of their 16th annual visit to Wales. Wockhardt carries out the "fill and finish" stage of the AstraZeneca vaccine manufacturing process. The couple also visited the headquarters of supermarket Iceland, in Flintshire. During a tour of the Wockhardt factory, which employs more than 500 people, the prince donned protective gear to visit the firm's quality control laboratory, where 300 million doses of the AstraZeneca vaccine are currently being produced. Quality control analyst Maggie Mutete talked Charles through the process of ensuring the vaccines were suitable for use. She said: "He was very lovely and it was a nice surprise. It's great to work on the vaccine, it keeps us on our toes. "We know that we are saving the world really. It's quite nice to be a part of and it's not something you can say every day."
