Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care. The research is published in Nature Communications.

It is necessary to develop additional COVID-19 vaccines, as different vaccine approaches have their advantages and disadvantages and may work synergistically. Researchers at Karolinska Institutet in Sweden now report that they have developed a prototype vaccine against SARS-CoV-2 using a DNA vaccine platform that is inexpensive, stable, easy to produce, and shows a good safety profile. A study published in Scientific Reports shows that the vaccine induces potent immune responses in mice.

Individual variations in how the immune system responds to SARS-CoV-2 appear to impact the severity of disease. Researchers at Karolinska Institutet have now been able to show that patients with severe COVID-19 have significantly elevated levels of a certain type of immune cells in their blood, called myeloid-derived suppressor cells. The study published in the Journal of Clinical Investigation may bring an increased understanding of how early immune responses impact disease severity.

Researchers at Karolinska Institutet have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells. The research study, published in Science, shows that a combined nanobody had a particularly good effect – even if the virus mutated. According to the researchers, the nanobodies have the potential to be developed into a treatment for COVID-19.

So far, little research has been done on the risk of children being seriously affected by COVID-19 when the schools were open.
