I'm not saying they haven't been, but, based on the Delta variant, it's not as simple as it was made to sound early in the year. Around this time last year, news broke that the Pfizer vaccine had been approved and I can remembered a virologist being interviewed on the day saying that things should be back to normal in the summer. Many people will say that they are, but how is it normal when, at current rates, there are a thousand people a week dying of Covid in the UK and the new cases figures are heading up again? I can remember 20,000 people dying in a year with flu and that was considered to be a very bad epidemic. Despite vaccines being available for nearly a year now, Covid will kill more than double that number if current rates are maintained and yet people some people talk of the pandemic in the past tense!
