It is a bit concerning that the Kent variant has developed some of the mutation that allows the SA and MBrazil/Manaus variant to partially evade immune systems. Clearly the government want to keep a lid on it which is why they are surge testing as they already have in other areas where it has been found like Southport etc
Clearly there is not yet iron cast evidence of its ability to evade vaccines etc as it hasn't spread very much and most people haven't been vaccinated so has no advantage over the ordinary Kent strain yet but this will change as more and more people are vaccinated so it needs to be contained until booster jabs against it are developed for the autumn.
Not sure why people dismiss the pp as scaremongering because we don't want people in those areas to be reluctant to take tests or dismiss the need for them as just scaremongering
