Covid-19: Vaccine blood clot research and warning over a big festival weekend

Here are five things you need to know about the coronavirus pandemic this Friday morning. We'll have another update for you this evening.

The Oxford-AstraZeneca coronavirus vaccine does raise the risk of blood clots and another serious condition - but the likelihood of such problems is much lower than it would be after suffering Covid. That's according to a study of more than 29 million people who received a first dose and nearly 1.8 million infected with the virus. Read more about the research.

Side-effects of the Pfizer-BioNTech vaccine in 12-to-15-year-olds at high risk from Covid are mild and clear up quickly, a small study suggests. Doctors in Bristol tracked 27 children with neurological conditions for two weeks after their jabs and found the youngsters, who had been shielding, had similar side-effects to adults.

Less than a quarter of the 37,000 rough sleepers housed by the government's Everyone In scheme have since moved into permanent accommodation, according to figures from councils obtained by Shelter. The housing charity warns many are still in temporary homes or back on the streets. The government says the analysis does not take into account those who have moved into supported housing or reconnected with family and friends.

Changes in shopping habits during the pandemic exacerbated difficulties for High Street retailers, resulting in the UK losing 83% of its main department stores in the five years since BHS collapsed, according to analysis. The data, compiled by commercial property information firm CoStar Group, reveals more than two-thirds of these big stores - 237 in total - remain unoccupied.

We're heading into a big festival weekend - with Creamfields, Reading and Leeds, and Lost Village all taking place. And for many young people it'll be the first chance to properly let their hair down for over 18 months. But, as Newsbeat reports, there are fears over a heightened danger of drug overdoses, with people's tolerance lowered during the pandemic.
