Thank you for posting this, it has received some news interest but doesn't tell us anything new in my opinion.

Paraphrasing, a non-peer reviewed preprint reports 34 young people (<30 years old) were paid £4565 to be deliberately exposed to Covid. Around half were not infected after the exposure and those that were infected had mild symptoms. Some of those who were infected were asymptomatic but were still shedding lots of virus.

I fail to see the point of this study which does not tell us anything we don't know already about the effects of Covid on young people. The numbers are far too small for the authors to be claiming any differences in findings from those seen in field studies

Perhaps...

...but it got them a paper in Nature, though!

It shows something, though I doubt they selected anyone for the trial who was considered in any way vulnerable. In that sense it was evidence of what they already knew. They're drilling down to a deeper level in order to find what it might have been that caused such discrepancies as there were.

Fairy Nuff!

There seems to be a deafening silence from Prof. Chris Whitty & Sir Patrick Vallance over Boris Johnson's plan to abolish all Covid regulations in England in two weeks' time.

Well, if Boris is out on foreign self-aggrandisement, he need not worry too much about what happens to his voters at home in UK?

Yes indeed. Either they agree with Johnson's actions or they don't. If the latter is the case, then they should speak out or resign.

Our family timeline has been extremely strange, so I'll share.
Day 1 - daughter well, told she was exposed at school
2 - daughter sick...vomiting and fever. Tests positive
3 - wife low grade fever (felt ill)..tested negative
4 - daughter feels 100% better
Day 5-6 - everyone fine
7 - wife vomiting uncontrollable
8 - wife tests positive...still vomiting.

My other daughter (special needs, numerous health issues) has been vomiting but has tested negative twice (pcr and antigen tests)

No cold symptoms for anyone. Just stomach issues and fever.

I'm completely fine. Weird

Sorry to hear about your family illnesses - but as you say - weird.

I hope you get through it all soon.

In the meantime it does suggest that there may be problems for all of us for some while - but they may not be at a level to attract much medical attention.

To think that they came through the bad bits and now are struggling (to put it mildly) with what is seen in many parts of the world as the better bit, as in not such a serious infection as the previous versions. As in this country now though the decision about what action to take seems to be political rather than pragmatic/science based.
