I thank my noble friend for this question. The ONS has provided this information and made it available for research purposes to make absolutely sure that we get to the bottom of this issue. For the understanding of noble Lords, every medical vaccine has side-effects, but the MHRA has investigated this, and the side-effect that people are worried about is heart inflammation. One to two people per 100,000 who have had a vaccine experienced side-effects, but, for people who have had Covid, it is 150 per 100,000. Having these vaccines is a much safer route to go.
