They find that fewer than 1 in 5 students (17.8%) had antibodies at the end of the Autumn term (which imples that more than 80% were susceptible to Covid).
"SARS-CoV-2 seroprevalence in 2,905 university students was 17.8% (95%CI, 16.5-19.3) ..."
"... ranging between 7.6%-29.7% across the five universities" (the universities are not named - 'University A' to 'University E')
"Seropositivity was associated with being younger likely to represent first year undergraduates (aOR 3.2, 95% CI 2.0-4.9), living in halls of residence (aOR 2.1, 95% CI 1.7-2.7) and sharing a kitchen with an increasing number of students ...
"(shared with 4-7 individuals, aOR 1.43, 95%CI 1.12-1.82; shared with 8 or more individuals, aOR 1.53, 95% CI 1.04-2.24). Seropositivity was 49% in students living in halls of residence that reported high SARS-CoV-2 infection rates (>8%) during the autumn term.
This highlights that nearly half of students living in halls of residence had Covid antibodies.

The Government's roadmap for reopening has been published.
I will add commentary as I read through.
From first glance, there are no numbers for thresholds, which does in some way question the notion of 'data not dates'.
There are however a lot of dates in the document.
The roadmap itself is only 15 pages long.
It sets out 'principles'
- whole of England rather than regional response
- "led by data not dates" (see above)
- five weeks between steps - 'no earlier than'
- face-to-face education a priority
On the face of it, this does seem to be more weighted to dates rather than data.
It will be interesting to see if *any* quantitative thresholds for cases, hospitalizations, or pressure on hospitals are set out on Monday, or whether the only thing that are set are dates.
It is obviously a risk, I'd reports are correct, to send all school children back on the same date. One critical thing missing is the ability to adapt. If R exceeds 1 and hospitalizations increase as a result of this, all that can be done is to close face to face...
schooling with the effect this will have on children's continuity of education. It would be prudent to send *some* children back and see the effect before committing all children.
Remember, it is not just the interactions between children (which *could* be mitigated...
