Germany announces first coronavirus vaccine trial

German Health Minister Jens Spahn has announced the first clinical trials of a coronavirus vaccine. The Paul Ehrlich Institute (PEI), the regulatory authority which helps develop and authorizes vaccines in Germany, has given the go-ahead for the first clinical trial of BNT162b1, a vaccine against the SARS-CoV-2 virus.

It was developed by cancer researcher and immunologist Ugur Sahin and his team at pharmaceutical company BioNTech, and is based on their prior research into cancer immunology.

In a joint conference call on Wednesday with researchers from the Paul Ehrlich Institute, Sahin said BNT162b1 constitutes a so-called RNA vaccine. He explained that innocuous genetic information of the SARS-CoV-2 virus is transferred into human cells with the help of lipid nanoparticles, a non-viral gene delivery system. The cells then transform this genetic information into a protein, which should stimulate the body’s immune reaction to the novel coronavirus.

The first medical tests of BNT162b1 will involve 200 healthy volunteers between the ages of 18 and 55. The aim is to determine the immune response and whether the vaccine causes any unwanted side effects.

“Trials of vaccine candidates in humans are an important milestone on the road to safe and efficacious vaccines against COVID-19 for the population in Germany and internationally,” the PEI said in a statement.

Cichutek said testing would be completed by June, at the earliest. After this stage is complete, the PEI will determine if the vaccine can progress to further trial stages. Cichutek warned, however, that an approved vaccine was unlikely to be ready for the general public in 2020.
