Can platelet size predict severity and mortality in COVID-19?

The ongoing COVID-19 pandemic has baffled researchers with its propensity to cause symptoms of largely unpredictable severity in the affected individuals. An exciting new study reports on the potential predictive value of platelet size in this situation. COVID-19 patients with severe disease often develop clots in vital organs, which leads to further complications. It is known that platelet size is a good indicator of activation.

mRNA-based COVID-19 vaccine CV07050101 demonstrates limited immunogenicity in non-human primates

Scientists from the US and Germany have recently evaluated the efficacy of an mRNA-based COVID-19 vaccine candidate, CV07050101, in inducing humoral and cellular immune responses in non-human primates. The study reveals that prime-boost immunization with the vaccine candidate induces only limited immunity against SARS-CoV-2.

New insight into how platelets help resolve bacterial lung inflammation

Treating patients with acute respiratory failure is a constant challenge in intensive care medicine. In most cases, the underlying cause is lung inflammation triggered by a bacterial infection or - more rarely, despite being frequently observed at present due to the corona pandemic - a viral infection.
