Summary

This trial tests a new COVID-19 booster vaccine for adults who either had previous mRNA vaccines or had COVID-19 but were not vaccinated. The vaccine aims to improve protection against the Omicron XBB.1.5 variant by enhancing the immune response.

Who is the study for?
This trial is for adults over 18 who've had an mRNA COVID-19 vaccine or are seropositive but unvaccinated. Participants must not join other SARS-CoV-2 studies during this time and should have no autoimmune conditions, allergies to vaccine ingredients, or history of myocarditis/pericarditis.
What is being tested?
The study tests a booster dose of the XBB.1.5 COVID-19 vaccine in previously vaccinated individuals and a single dose in those unvaccinated but with natural immunity. It's open-label, meaning everyone knows which treatment they're getting.
What are the potential side effects?
Potential side effects may include typical reactions like soreness at the injection site, fever, fatigue, headaches, muscle pain, chills and possible allergic reactions.

Other Research
Common treatments for COVID-19, such as the XBB.1.5 SARS-CoV-2 recombinant spike protein nanoparticle vaccine adjuvanted with Matrix-M™, work by enhancing the immune system's ability to recognize and combat the virus. This vaccine presents the spike protein to the immune system and uses the Matrix-M™ adjuvant to boost the immune response. Similar mechanisms are seen in mRNA vaccines, which instruct cells to produce the spike protein, and antiviral drugs like Remdesivir, which inhibit viral replication. Monoclonal antibodies provide direct immunity by targeting the virus. These treatments are essential as they help prevent infection, reduce viral load, and alleviate severe symptoms, ultimately improving patient outcomes.
