Summary

This trial tests new doses of COVID-19 vaccines, including those for new variants, in healthy adults who have already received all initial doses. The goal is to see how well these additional doses improve the body's ability to fight the virus and its new versions. Booster doses help maintain protection.

Who is the study for?
Adults aged 18+ in stable health who've completed their primary COVID-19 vaccination series and booster at least 16 weeks prior can join. Those with stable chronic conditions may be eligible. Excludes pregnant/breastfeeding individuals, those with advanced liver/kidney disease, recent investigational vaccine or antibody therapy recipients, and people with certain medical histories like myocarditis.
What is being tested?
The COVAIL Trial is testing the safety and immune response to various prototype and variant COVID-19 vaccines (alone or combined) in adults previously vaccinated against SARS-CoV-2. It's an open-label trial where participants are randomly assigned to receive one of several variant vaccines.
What are the potential side effects?
Potential side effects include typical vaccine reactions such as soreness at injection site, fatigue, headache, muscle pain, chills, fever, nausea; rare risks may involve allergic reactions or heart inflammation known from other mRNA vaccines.

Other Research
The most common treatments for COVID-19 include antiviral drugs, monoclonal antibodies, and vaccines. Antiviral drugs, such as remdesivir, inhibit viral replication by targeting viral RNA polymerase. Monoclonal antibodies, like those targeting the spike protein of SARS-CoV-2, neutralize the virus and prevent it from entering host cells. Vaccines, including those studied in the SARS-CoV-2 variant vaccine trials, aim to induce a robust humoral immune response by stimulating the production of neutralizing antibodies. This is crucial for COVID-19 patients as it helps to prevent severe disease, reduce viral load, and limit the spread of the virus.
