The world's first human challenge trial in which volunteers were deliberately exposed to Covid-19 to advance research into the disease was found to be safe in
healthy young adults, one of the companies running the study said on Wednesday.
The data supports the safety of this model which could theoretically provide a "plug and play" platform for testing therapies and vaccines using the original
Covid-19 strain as well as variants of the virus, Open Orphan, which carried out the study, said in a statement.
Open Orphan is running the project, launched a year ago, with Imperial College London, the UK government's vaccines task force and the clinical company hVIVO.
The trial infected 36 healthy male and female volunteers aged 18-29 years with the original SARS-CoV-2 strain of the virus and closely monitored them in a controlled
quarantined setting. They will be followed up for 12 months after discharge from the quarantine facility.
The Hormone Replacement Therapy (HRT) Taskforce head Madelaine McTernan has returned to working full time as the director general of the Vaccine Taskforce for
autumn booster campaign preparation.
She has presented a few key recommendations to help ensure continued HRT supply to meet rising demand. "Improved access to data on prescriptions to more easily see
where there are shortfalls between HRT packs prescribed and HRT packs supplied by manufacturers," she suggested. "Taking lessons from the HRT supply chain work to
inform broader medicine supply work."
Madelaine said: "I am pleased to see the situation with HRT supply is improving across the country. I want to thank suppliers and manufacturers for their engagement
and positive action to tackle this serious issue.
