That one is a viral vector vaccine – the gene that codes for the SARS-CoV-2 spike protein is carried inside a “shell” created from an adenovirus particle, which itself cannot replicate or ...

A new study has shown promising results for a nasal COVID-19 vaccine. Getty Images/iStockphoto Johnson & Johnson’s Janssen is a viral vector vaccine, which delivers DNA “instructions” to the ...

What is a viral vector? Viral vector vaccines use a version of a mild virus to safely deliver instructions in the form of genetic code to our body cells. These instructions enable your body to produce ...

Viral-vectored vaccines can be designed quickly. One concern is that people can develop immunity to the viral vector, making this approach potentially less useful if booster shots need to be given.

Crucially, this vector poses no threat to humans, enhancing the vaccine's safety profile. In 2022, researchers from the department Viral Immunology headed by Prof. Luka Cicin-Sain at the Helmholtz ...

The largest COVID vaccine study to date has identified some risks associated with the shot. Researchers from the Global Vaccine Data Network (GVDN) in New Zealand analyzed 99 million people who ...

Intranasal influenza virus-vectored vaccine offers protection against clade 2.3.4.4b H5N1 infection in small animal models. Nature Communications , 2025; 16 (1) DOI: 10.1038/s41467-025-58504-z ...

It’s a more traditional vaccine — something called a viral vector vaccine. A viral vector vaccine uses a modified version of a different virus — in this case, Adenovirus 26. This is a virus ...

The biotech giant that soared during Operation Warp Speed now faces regulatory hurdles, political scepticism, and dwindling ...

Transgene (Euronext Paris: TNG), a biotech company that designs and develops virus-based immunotherapies for the treatment of cancer, today announced that its management team will meet institutional ...
