Summary

This early-stage study tests two experimental COVID-19 booster vaccines alongside two authorized ones in 48 healthy adults aged 18-65 who have already received at least two mRNA COVID-19 shots. The goal is to check safety and measure how well the vaccines boost the immune system. Participants receive one injection and attend 10 visits for blood and saliva tests over about a year.
