Nanoparticles that have been fortified with immune fighting properties can help to boost the effect of vaccines, scientists are claiming.

When injected into the body at the same time as a vaccine the nanoparticles stimulate the lymph nodes, where the majority of immune system reactions originate from.

This then encourages the immune system to react quickly to infections or viruses as soon as they enter the body and therefore makes the vaccines more effective.

After successfully testing the new nanoparticles on mice, the researchers are hoping they will soon be ready for use with human vaccines.

Scientists at the Duke University Medical Centre in America carried out the study and tested the effects of the nanoparticles alongside a vaccine for the influenza A virus.

The leader of the investigation, Dr Ashley St John, commented on the findings.

“Our strategy is unique because we have based our bioengineered particles on those naturally produced by mast cells, which effectively solve the same problem we are trying to solve of combating infection,” he said.

The bolster chemicals – otherwise known as adjuvants – which are currently added to vaccines to enhance their effectiveness do not travel to the lymph nodes.

Although the adjuvants do enhance immunity, it is thought this only occurs at the site of injection.

Commenting further on the findings, Dr Soman Abraham, who was involved in the research, told BBC News: “There is a lot of interest in nanoparticle-based therapy, but we are basing our materials on our observation of mast cells in nature.

“This is an informed application to deliver the right material to the right place in the body to get the most effective immune reaction.”

The results of the research have been published in the journal Nature Materials.

Microsoft launches Tech for Social Impact for elderly care

Microsoft launches Tech for Social Impact for elderly care
Microsoft's programme will make innovative tech accessible to non profits in the elderly care sector around the world

Microsoft Tech for Social Impact, the tech giant's division offering tools for non profit organisations, has announced it is expanding to include aged care non profits around the world. 

This means that non profit organisations helping elderly residents in nursing homes or with other daily support will now be eligible for technology grants and discounts of up to 75%, as well as training and capacity building to help with digital transformation. 

The care home sector has been one of the hardest hit by the COVID-19 pandemic, caring for some of the most vulnerable people in society. As a result organisations around the world have been deploying innovative technologies, such as IoT to create monitoring solutions that enable independent living, through to AI-driven robots that provide companionship as well as alert the user's care team if there are any changes to their symptoms. 

The German Red Cross (DRK) is an early adopter that is already benefitting from this programme expansion as part of Microsoft Tech for Social's pilot scheme.  DRK provides services and assistance to over 40,000 people at more than 500 aged care facilities in Germany, with a further 90,000 receiving care in their own homes. 

Thanks to Microsoft 365 cloud technologies such as SharePoint and OneDrive, along with Teams for communication, DRK was able to continue its daily work even at the height of the pandemic crisis. Residents of DRK facilities used Teams to keep in touch with relatives despite restrictions to visits, and there are plans to continue using these channels in the future to prevent isolation among residents. 

Following the pilot’s success, the programme will offer discounts and grants to eligible organisations for its Microsoft cloud stack including Business Applications, Azure and Modern Work,  leveraging the firm's sector-specific tools with Microsoft Cloud for Nonprofit which will be generally available in the second half of 2021.

Microsoft estimate that around 75,000 new non profit organisations around the world will be eligible for the programme.
