The coronavirus vaccination centre opened at Asda in Watford on Thursday A couple cooped up in their home for the best part of a year could not hide their delight and relief after being given the first dose of their coronavirus vaccine. Maria Waller and her husband Phil were among the first people people to pass through the doors at new Covid vaccination centre at Asda in Watford. The couple had travelled from Berkhamsted for the vaccine after Mr Waller received an invitation letter from the NHS. And as they sat in the observation room for 15 minutes after their jabs on Thursday, the couple, who were among two million people told to shield during the first lockdown, seemed over the moon not only by receiving the jab but also their experience in getting it.
