Halifax trial for made-in-Canada vaccine struggles to find new recruits

Researchers are encountering challenges recruiting participants in a clinical trial of a Canadian made COVID-19 vaccine because of how widespread immunization among the public has become. Entos Pharmaceuticals is undergoing trials with its vaccine candidate in Halifax but is having trouble finding eligible participants who have not received a Health Canada authorized vaccine or been infected with COVID019. They hope to recruit 500 adults in their 20’s for a phase 2 trial in July. A small sample of adults aged 65-85 will likely have to be sought in a different location due to high vaccination rates among that group in Nova Scotia. Entos believes its vaccine will offer protection as a single dose and will be able to be stored at room temperature for a month, or in regular refrigeration for up to a year.
