COVID-19 Trial Summary

This trial tests two new COVID-19 vaccines to see if they're safe and effective in teens who already got an mRNA vaccine.

Who is the study for?
Adolescents aged 12 to under 18 who are medically stable and have had at least two doses of Moderna or Pfizer-BioNTech COVID-19 vaccines can join. They must not be pregnant, planning pregnancy, or breastfeeding, agree to contraception if applicable, and avoid other COVID trials.Check my eligibility
What is being tested?
This study tests the safety and immune response of a new Omicron XBB.1.5 variant vaccine in teens previously vaccinated with mRNA COVID-19 vaccines. It's randomized and double-blinded, meaning participants don't know which vaccine they receive.See study design
What are the potential side effects?
Potential side effects may include typical reactions seen with vaccines such as soreness at injection site, fever, fatigue, headache or allergic reactions but specific side effects for this new vaccine will be closely monitored.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Immunogenicity index- Neutralizing antibody (NAb) expressed as geometric mean titers (GMTs) to the Omicron XBB.1.5 strain.
Immunogenicity index- The Neutralizing antibody (NAb) expressed as geometric mean fold rise (GMFR) to the Omicron XBB.1.5 strain.
Safety: Incidence and severity of (MAAEs) attributed to study vaccine, (AESIs) (PIMMCs), myocarditis and/or pericarditis, and complications specific to COVID-19), and serious adverse events (SAEs)
+2 more
Secondary outcome measures
IgG geometric mean ELISA (enzyme-linked immunosorbent assay) units (GMEUs) to the Omicron XBB.1.5 S protein.
NAb(neutralizing antibody titers) and IgG GMEUs levels are measured to the ancestral (Wuhan) strain .
Neutralizing antibody (NAb) expressed as geometric mean fold rise (GMFR) to the Omicron XBB.1.5 strain.
