Norovirus clinical trial

UK’s first-ever norovirus mRNA vaccine trial launched in Wales 

Help to see if we can protect people against symptoms caused by the norovirus stomach bug with an investigational mRNA vaccine. 

The North Wales Clinical Research Facility (NWCRF) is looking for participants for the Nova 301 Trial. This trial will see if an investigational vaccine can protect people 60 years of age or older against symptoms caused by the norovirus stomach bug. 

About the norovirus stomach bug 

Norovirus is one of the most common stomach bugs in the UK. It can spread easily and most cases are often in care homes and schools. The norovirus stomach bug can cause many unpleasant symptoms like nausea, vomiting, and diarrhoea.  

About the Nova 301 Trial 

The Nova 301 Trial will see if an investigational vaccine (a vaccine that is being studied) may be able to prevent symptoms caused by the norovirus stomach bug from developing in people 18 years of age or older. The investigational vaccine in this clinical trial is called mRNA-1403. You cannot catch norovirus by having this investigational vaccine.
