Young people who have previously had COVID-19 are to be deliberately exposed to the virus for a second time.
It’s all part of a new study that aims to monitor how their immune systems react.
The University of Oxford’s “human challenge” trial – which is being widely reported on this morning – also hopes to discover what dose of coronavirus (COVID-19) is needed to cause a reinfection, and what this may mean for developing protective immunity against the disease.
The decision to carry out the study comes after recent research has suggested that prior infection may not fully protect young people from COVID-19 in the future, with an observational study performed in the US indicating that 10% of participants ended up getting reinfected.
So, what does the study entail then?

As part of the trial, young people – between the ages of 18 to 30 – who have previously already been naturally infected with COVID-19, will be recruited and then re-exposed to the virus in a safe, controlled environment, all while being quarantined for 17 days and cared for by researchers at a hospital until they are no longer at risk of infecting others.
Once the trail is complete, participants will then receive just under £5,000 as payment.

The first phase – which will involve 64 healthy volunteers – aims to establish the lowest dose of virus which can take hold and start replicating, and once the dosing amount is established, it will be used to infect participants in the second phase of the study.
Regular check-ups in the year after reinfection will also help to establish the immune response generated by the virus, as well as contributing to the creation of better vaccines and a greater understanding of how long immunity lasts.

Professor Helen McShane, the chief investigator, said: “Challenge studies tell us things that other studies cannot because, unlike natural infection, they are tightly controlled.
“When we reinfect these participants, we will know exactly how their immune system has reacted to the first COVID infection, exactly when the second infection occurs, and exactly how much virus they got.
“As well as enhancing our basic understanding, this may help us to design tests that can accurately predict whether people are protected”.
The trial is expected to start in the summer.

Seven Manchester green spaces have been named some of the best in the UK

A handful of green spaces in Manchester have once again been handed coveted awards and named among the best in the UK.
It may be on your radar that for several years running now, parks and cemeteries in Greater Manchester have deservingly been recipients of the prestigious Green Flag Award – which is an internationally-recognised honour given annually to the parks and cemeteries that have ‘attained a high standard of green space’.
And 2026 seems to be absolutely no different, with the region coming out on top once again.
Green Flag Awards are granted by environmental charity Keep Britain Tidy each year to recognise accessible green spaces that set ‘an international benchmark for management’.

Every site recognised through the scheme is assessed by experienced judges who judge the parks using eight criteria.
The criteria includes environmental management, biodiversity, landscape and heritage, community involvement, marketing and communication, and management to make sure it’s a safe and secure place for visitors of all ages.
2026 has been one of Manchester’s most successful years, as Manchester City Council has revealed this week that Blackley, Gorton, Philips Park, Manchester General, and the Southern cemeteries have all been given the Green Flag Award, as well as both Alexandra Park and Heaton Park retaining the important title too.
The awards shed light on the range of groups, volunteers, and staff who devote themselves year-round to the maintenance and upkeep of these areas.
“Come rain or shine our colleagues are out in our parks and cemeteries every day of the year, putting their time and effort into making them the internationally recognised locations they are,” commented Councillor Basat Sheikh, who is the Executive Member for Neighbourhoods at Manchester City Council.
“I’m deeply proud of their efforts and I want to dedicate the seven Green Flags we have been awarded to them.
“It’s no overstatement to say none of this would be possible without them.”

Government announces social media curfew for 16 and 17-year-olds in the UK
Emily Sergeant
Default overnight curfews are set to be switched on for 16 and 17-year-olds on social media apps.
As the Government looks to take further action to back parents and ‘protect the next generation’ online, following the confirmation of the social media ban for under 16s earlier this year, it has now been announced that curfews will be introduced for 16 and 17-year-olds, as well as a crackdown on so-called ‘addictive features’.
This includes features that can keep users scrolling for longer – such as videos that automatically play one after another, and feeds that continually serve up personalised content.
Late-night curfews are set to run from midnight to 6am.
Late-night scrolling. Endless autoplay. Algorithms designed to keep you hooked.
We're changing that for 16 and 17-year-olds.

The new protections are said to be aiming to ‘strike a balance’ between giving older teens greater safeguards online, while still allowing them to change their own settings if they wish.
“These measures will help ensure there is no cliff edge in protections as young people move into their later teenage years,” the Government said in its announcement.
Today’s measures follow a first-of-its-kind Government pilot involving more than 300 teenagers and parents across the UK, with families reporting that overnight curfews quickly became part of their routine and helped improve sleep and concentration.

“These measures will be crucial in helping young people get the sleep they need, focus on school and college, and spend more quality time with family and friends, all of which are fundamental to building a happy, healthy and fulfilling adult life,” explained Technology Secretary, Liz Kendall.
“We want young people to enjoy the benefits of technology while having the tools to make the online world a place where they can thrive.”
Alongside these protections, the Government says it will publish new guidance for children, parents, and guardians on how to use AI ‘safely and confidently’.
Media literacy skills will also be bolstered in schools to teach children how to navigate new types of technology.
