I think Guy is right to point out that it is normal for vaccine tests to be paused, and that the emergence of unexpected symptoms is helpful in the learning which has to take place.
It is, however, not a short process to develop a vaccine - for obvious reasons - and expectations that we may have one this year are optimistic to say the least, when usually it is a 2 year (or more) process.
I think the schools opening and forthcoming university openings are something to be concerned about, and a working Test and Trace system is essential. Not to have one fully operative at this stage is very worrying.
Instructions that suggest it's fine to go back to work (why aren't you back already all you people who've been 'idle' at home - when many have been working throughout, I certainly have),
and safe to go back to school/university,
as well as to support restaurants and encourage dining out with discounts,
whilst it's apparently 'not safe' to have meetings of more than six people,
are hugely confusing.
And when it's confusing, then people don't know what to do, and are more likely to either do nothing or - inadvertently - the wrong thing.
