Scientists trick body for better immunity with disguised vaccine
Before the COVID-19 pandemic, few had heard of mRNA vaccines. A major advantage of mRNA technology is its rapid adaptability without developing new vaccines from scratch. However, protective immunity decreases quickly. Researchers from the University of Copenhagen are working to address this issue and found a way to make the technology more effective. A team, including scientists from the university and biotech company AdaptVac, has combined two types of genetic codes in one vaccine, producing virus-like particles that prompt a strong immune response in mice. Senior researcher Cyrielle Fougeroux and Professor Adam Sander, the study’s last author, noted this significant advancement in mRNA technology. Human testing may begin within years, with current efforts focusing on a vaccine against the Nipah virus, a zoonosis listed by WHO as a potential future pandemic.
