Last night I had a look at a short video on YouTube from Sky News which was about the current Covid situation here in the UK vs mainland Europe, and the 'conundrum' that cases aren't currently skyrocketing in the UK, unlike certain mainland European nations such as Austria, Germany, etc, where daily cases have reached all-time pandemic highs.
In addition to greater numbers of vaccinated in the UK, the fact that we reopened much earlier than most of mainland Europe and even our immediate neighbours the Republic of Ireland, is most ironically believed to have provided many of us Brits with greater herd immunity, plus the vast majority of cases since 'Freedom Day' reportedly being in the younger generations, of whom are usually more resilient and less likely to be hospitalised and/or die of Covid. Dr JC also mentioned this the other day in one of his videos.
BTW, I shall be getting my third booster jab this afternoon, so that will be my entire family done at least for this season.
