It was probably Delta as 99% of cases in UK are. I know of quite a few vaccinated friends who&amp;#x27;ve caught it recently too. Mainly AZ I think but one was Pfizer (single jabbed).&lt;p&gt;Anyway, none of us had severe illness although I felt pretty rough for a few days like I had a really bad cold and smell went for a week completely. I was basically fine though and everyone else I know is too who got it recently. The point is that it does seem like this Delta variant breaks through regularly and it does seem (again, purely anecdotal) like it&amp;#x27;s v infectious. Of course the thing to emphasise is that, whilst it might break through, the vaccine still stops serious illness to a high degree. It does highlight however the need to not be complacent. Vaccines don&amp;#x27;t seem to be stopping the spread right now as much as you might think, and the high number of cases combined with high vaccination rates is an obvious selection pressure.  More variants are inevitably coming and it does seem like this virus is bucking the trend and not necessarily becoming less potent despite increased tranmissability in some variants&lt;p&gt;My conclusion is that, whilst I welcome the UK being sort of &amp;quot;back to normal&amp;quot;, let&amp;#x27;s keep up the mask wearing, hygiene standards and so on. It&amp;#x27;s a balance but I sense things are getting a bit too lax. I&amp;#x27;m not overly anxious but let&amp;#x27;s stick to the precautionary principle a bit more.</text></comment>

To be honest, I stopped following news since being fully vaccinated some time ago, so I am kind of ignorant here.&lt;p&gt;Is the main problem, the unvaccinated, or that the Delta (and co.) variants are still, too dangerous for vaccinated people? Or is it the fear, that they will get more dangerous?</text></comment>
