A needle-free vaccine patch could better fight COVID-19 variants, such as Omicron and Delta, than a traditional needle vaccine according to a University of Queensland study in mice.

The SARS-CoV-2 that causes COVID-19 has killed 6.3 million people worldwide since 2019, painfully highlighting the vulnerability of humanity to novel coronaviruses.

Despite significant and stunning advances in vaccine technology, the COVID-19 global pandemic is not over. A key challenge in limiting the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is identifying infected individuals.

What happens in our respiratory tract once COVID-19 invades? A three-dimensional airway model, made from patient-derived stem cells, could provide answers about the initial stages of infection. The model not only replicates the infection process, but can be used to test potential antiviral drugs.

Emergex Vaccines Holding Limited (‘Emergex’, or ‘the Company’), a company tackling major global infectious disease threats through the development of 100% synthetic T Cell priming vaccines today announces that it has received the necessary regulatory approvals to initiate a Phase I clinical trial to evaluate the safety and tolerability of its vaccine candidate for SARS-CoV-2, the virus which causes COVID-19.

Throughout the COVID-19 pandemic, there has been much uncertainty about how long immunity lasts after someone who is unvaccinated is infected with SARS-CoV-2.

Scientists at Lausanne University Hospital (CHUV) and EPFL have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant.
