Researchers worldwide are trying to develop a vaccine and antiviral treatments against the new corona virus spreading in China. At Karolinska Institutet, virus researchers Ali Mirazimi and Matti Sällberg are working to develop a prototype vaccine against the virus. But vaccine development takes time, and it will likely take at least six to nine months before an application for clinical studies can be filed and another two to three years before a vaccine could be ready for the public.

Babies born with low birth weights are more likely to have poor cardiorespiratory fitness later in life than their normal-weight peers. That is according to a study by researchers at Karolinska Institutet in Sweden published in the journal JAHA. The findings underscore the importance of prevention strategies to reduce low birth weights even among those carried to at term delivery.

When Human Immunodeficiency Virus Type 1 (HIV-1) infects a cell, the virus often becomes invisible to both the immune system and drugs. Now research from Karolinska Institutet shows that the integrated virus mimics a specific chromatin structure that lets the virus sequence remain accessible while preventing production of new viruses.

In a recent study, researchers from the Karolinska Institutet show that the estrogen receptor beta (ERß) affects nerve signals in the part of the brain that controls locomotor activity. The results highlight the importance of ERß and the female sex hormone estrogen in brain development and function, and that an imbalance of the hormone could contribute to neuropsychiatric disorders.

A clinical phase I study led by the Public Health Agency of Sweden and researchers from Karolinska Institutet shows that a new vaccine for pertussis (whooping cough) given as drops into the nose is more efficacious than the current vaccine.
