A Swansea University research study of NHS frontline workers is underway to investigate if seaweed could be a powerful ally in preventing COVID-19.
The study of 480 frontline Swansea NHS workers by Swansea University investigates the efficacy of an over the counter cold remedy from high street chemist Boots, in preventing COVID-19 illness and reducing the severity of COVID-19 symptoms.
Boots Dual Defence which contains Carragelose, a patented version of iota-carrageenan and a form of seaweed, is already clinically proven to help shorten the duration and severity of cold and flu-like symptoms, and a new test tube laboratory study results suggest that Carragelose could also reduce the risk of an infection with SARS-CoV-2, the virus which causes COVID-19.
These promising results will be further validated in a new clinical trial, ICE-COVID, which will investigate whether Dual Defence can either prevent COVID19 infection or reduce severity of symptoms in humans compared with placebo. Professor Ron Eccles, cold and flu expert and former director of the Common Cold Centre at Cardiff University is co-investigator on the research study and will work closely with the Chief Investigators at Swansea University, Professor Iain Whitaker, Surgical Specialty Lead for Health & Care Research Wales and Professor Hayley Hutchings, Co-Director of the Swansea Trials Unit.
Dr Zita Jessop, the Principal Investigator for the clinical trial and clinician scientist at Swansea University, whose MRC funded doctorate was based on biomaterial science.
Dr Jessop describes her motivation for setting up the clinical trial “After seeing the effects of this pandemic on colleagues caring for patients with COVID-19, we wanted to find a way for research to help protect frontline NHS staff. Previous studies highlighted the effectiveness of iota-carrageenan-based nasal sprays against coronaviruses, indicating promise against SARS-Cov-2. If the results of this randomised placebo-controlled clinical trial are positive as we expect, this has the potential to add an extra prevention strategy in the fight against COVID-19.”
Richard Evans, Executive Medical Director, Swansea Bay University Health Board added: “We’re delighted that Swansea Bay University Health Board is able to contribute to this research. Although the prospect of effective vaccines is now on the horizon, it’s still vitally important that we explore all opportunities to investigate new treatments for COVID-19 and we’re pleased to be playing a part in that global effort.”
Carragelose is a patented version of iota-carrageenan and is generated from consumable red seaweeds occurring naturally throughout the world. The ingredient is exclusively available in Boots Dual Defence Nasal Spray in the UK and Carragelose is patented and invented by Marinomed in Austria. It acts as a barrier by forming a gel to trap cold and flu virus particles as they enter the body, therefore reducing the likelihood of infection or reducing the amount of virus entering the body and therefore reducing the severity of symptoms.
It is anticipated that results of ICE-COVID will be published in March 2021.

Wales extends COVID-19 testing throughout July
Welsh Health Minister, Eluned Morgan has confirmed that access to free LFD tests will be extended in Wales until July 31st 2022.
Tests will be available to the public that are showing symptoms of coronavirus (high temperature a new, continuous cough, a loss or change to your sense of smell or taste), alongside free access for people visiting someone eligible for new COVID-19 treatments.
The announcement comes following a rise in cases, with The Office for National Statistics recent survey reporting an increase in cases across the UK. An estimated 1 in 45 people in Wales currently have COVID-19.
The emergence of the BA.4 and BA.5 sub-variants are also contributing to this increase as they become more dominant across the UK.
The health minister has also announced the following testing will continue to be in place –
- LFD and PCR testing for those eligible for COVID-19 treatments.
- PCR testing for COVID-19 and other respiratory viruses for symptomatic care home residents and prisoners.
- PCR and LFD testing under the patient testing framework and when clinically advised including pre-operative hospital patients and care home residents returning from inpatient hospital stays
- LFD testing for symptomatic health and social care staff.
- Twice weekly LFD tests for asymptomatic testing for health and social care staff
- Those visiting people in care homes should continue to test using tests provided by the care home they are visiting.
Self-isolation payments of £500 will end on 30th June 2022, whilst the COVID-19 Statutory Sick Pay Enhancement scheme will be extended until 31st August 2022 to support social care staff to stay away from work due to testing positive.
Minister for Health and Social Services, Eluned Morgan, said: “Testing has been an effective tool in breaking the chain of transmission and with an increase in cases its vital that we keep testing in place to protect the most vulnerable in our society. As we have seen before, Covid can quickly change, I am announcing this extension in response to the changing picture and new variants of concern.
“I would also ask people to take protective measures to protect the more vulnerable in the community, wear masks in health and care settings, stay at home if you test positive, and take up the offer for the vaccine. We know that the vaccine is the best way to protect yourself, I would urge those eligible to have their spring booster if they have not already had it, the booster is available until June 30.
“Covid has not gone away, whilst we are learning to live safely with it, we will continue to monitor the situation and as we have done for the last two years, we will work together to Keep Wales Safe.”
Coronavirus regulations to end in Wales
First Minister Mark Drakeford today said Wales can look forward to a brighter future, as the last remaining coronavirus protections in law come to an end.
After more than two years of living with coronavirus regulations, these will expire on Monday May 30 when the requirement to wear a face covering in health and care settings ends.
But the Welsh Government will continue to recommend people take simple steps to protect their health – including wearing face coverings in health and care settings – as Wales moves beyond the emergency response to the pandemic.
First Minister Mark Drakeford said: “The pandemic has had a profound impact on all our lives – everyone has made sacrifices and changes over the last two years. But it is thanks to all your efforts that we can move beyond the emergency response while still living safely with this virus.
“I want to thank everyone for all you have done to protect yourselves and your loved ones. You have followed the rules and you have kept Wales safe.
“This three-week review of the coronavirus regulations is a significant milestone – we are completing our careful and gradual transition away from legal protections and away from the emergency response to the pandemic.”
The public health situation is continuing to improve in Wales – results from recent ONS Coronavirus Infection Surveys show the number of people with Covid-19 is falling.
But in the past week, the four UK chief medical officers have warned about the risk from new variants – BA.4 and BA.5.
The First Minister said Wales will remain alert to these and is ready to scale up testing and vaccination arrangements once again if the public health situation changes.
He added: “We remain alert to the threat of new and emerging variants, and we will be ready to respond if we see a rapid spread of the virus, causing widespread harm.
“Continuing to take simple steps, including staying up to date with vaccinations; self-isolating if you have Covid-19 symptoms and maintaining good hand hygiene, will be important in helping us all to enjoy a safer and brighter future together.”
From Monday 30 May, the legal requirement to wear a face covering in health and care settings will end. This follows the outcome of the three-weekly review of coronavirus regulations and completes a gradual, phased easing of legal restrictions since January.
Over the last three weeks the public health situation has continued to improve, with the latest results from the ONS Coronavirus Infection Survey showing the percentage of people testing positive for coronavirus in Wales is falling.
The number of Covid-19 related patients has also fallen to less than 700 and is at its lowest level since 28 December 2021, although the NHS remains under pressure from a combination of emergency and pandemic pressures with a significant number of staff absences.
New COVID vaccination centre opens at Aberavon Shopping Centre
A new COVID vaccination centre for Port Talbot is opening at Aberavon Shopping Centre.
Situated next door to B&M, near the river bridge entrance, Swansea Bay Health Board say it will provide vaccinations to adults and children alike.
The first clinic will be held at the Local Vaccination Centre (LVC) on Thursday, May 26th. Slots will be available by appointment only for the time being.
The health board are asking people not to telephone the shopping centre if they want to make an appointment or if they have a general query. The health board’s booking centre can be contacted on 01792 200492 or 01639 862323.
The opening comes as the health board winds down its vaccination operation at the Bay Field Hospital near Amazon, off Fabian Way, which has been open since the first Covid vaccine was rolled out to health and social care staff in December 2020.
The final Covid vaccination clinic will be held at the Bay Mass Vaccination Centre on Wednesday, June 1st.
Blood tests will continue on that site for the time being.
Covid vaccination clinics will also continue to be scheduled at Canolfan Gorseinon Centre, in the health board’s container in the car park of Morrisons supermarket on Baglan Industrial Park and on the Immbulance mobile vaccination clinic, which stops at various venues across the Swansea Bay area.
Interim Head of Transformation, James Ruggiero, said the move to the shopping centre signals a wider change in the Covid vaccination programme.
“The Bay has been absolutely brilliant for us but thankfully, we no longer need a permanent venue of that size.
“While no one can predict exactly what will happen in the future, we do know that some people, particularly those who are vulnerable, will need Covid boosters to help maintain a level of protection against the coronavirus, which is still out there.
“This new venue is perfect for that and a bonus is that being smaller and less intimidating, it can also be used to host clinics for children aged five to 11.”
Mr Ruggiero added: “Our teams have worked hard to set up this new convenient unit and to make it as comfortable and efficient as possible.
“We hope the public welcome it and enjoy popping to the other shops to pick up a bargain once they’ve come in for their vaccination.”
The Aberafan Shopping Centre LVC will be open between 9.30am and 4.30pm. Vaccinations are on an appointment-only basis for now.
The first vaccinations will be for the spring booster which, in line with JCVI guidance, is being given to those aged 75 and over, older care home residents and those aged 12 and over who are immunosuppressed.
The health board will shortly be announcing clinic dates for those aged five to 11 in June.
A Covid booster programme is due to run in the autumn, with interim JCVI advice saying that Residents in a care home for older adults and staff working in care homes for older adults; Frontline health and social care workers; All those 65 years of age and over; and adults aged 16 to 65 years in a clinical risk group should each receive one dose.
