Question: How long should people in vulnerable groups continue to shield?

Answer passage (source: UK):
page_title: Guidance Guidance on shielding and protecting people who are clinically extremely vulnerable from COVID-19
section_headers: Staying at home and shielding
section_content: If you’re clinically extremely vulnerable, you’re strongly advised to stay at
home at all times and avoid any face-to-face contact to protect yourself.
This is called ‘shielding’ and the advice is:

Do not leave your house.
Do not attend any gatherings, including gatherings of friends and families in private spaces, for example, family homes, weddings and religious services.
Strictly avoid contact with someone who is displaying symptoms of coronavirus (COVID-19).

The Government is currently advising people to shield until 30 June 2020 and
is regularly monitoring this position.

Reviewer feedback on this answer:
This information gives good advice on shielding, but the question isn't directly answered.  It doesn't state how long the people should shield.
This is an excellent answer because it gives an exact date as to how long people need to be 'shielding'. It also gives more clarification as to what shielding is, and how to do it.

Answer passage (source: UK):
page_title: Guidance Staying alert and safe (social distancing)
section_headers: Protecting different groups of people
section_content: This guidance is for the general public who are fit and well. There is
separate, specific guidance on isolation for households with a possible
coronavirus infection.
Some people, including those aged 70 and over, those with specific chronic
pre-existing conditions and pregnant women, are clinically vulnerable, meaning
they are at higher risk of severe illness from coronavirus’. As we begin to
ease restrictions, this group who are clinically vulnerable – see section 8 –
should continue to take particular care to minimise contact with others
outside their household.
There is a further group of people who are defined, also on medical grounds,
as clinically extremely vulnerable to coronavirus – that is, people with
specific serious health conditions. They are advised to continue
shielding measures to keep
themselves safe by staying at home and avoiding all contact with others,
except for essential medical treatment or support.

Reviewer feedback on this answer:
There is little mention specifically to shielding here.  The question isn't directly answered.  It doesn't state when people should shield until.
This answer is bad because it provides no date or time frame as to how long people need to be shielding. Therefore, it does not answer the question.

How long will shielding be in place?
section_content: We’ve advised individuals with very specific medical conditions to shield
until the end of June and to do everything they can to stay at home. This is
because we believe they are likely to be at the greatest risk of serious
complications from coronavirus.
We know this is challenging guidance to follow, which is why we have a support
scheme in place to provide help with access to food and basic supplies, care,
medicines and social support.
We are keeping the guidance to shielded
people under review.

Reviewer feedback on this answer:
The answer here is direct.  It states that people in this group should try to shield until the end of June.
This is an excellent answer because it gives a straightforward answer as to how long people need to be shielding. The answer states specifically until the end of June.
