Summary

This trial is testing two new vaccines, AZD9838 and AZD6563, in healthy adults to see if they are safe and help the immune system fight COVID-19.

Who is the study for?
Adults aged 18-64 with a BMI under 35, who've had COVID-19 or been vaccinated against it at least 6 months ago. They must test negative for SARS-CoV-2 and be medically stable. Pregnant women, recent vaccine recipients, those with certain allergies or heart issues, and individuals with immune conditions are excluded.
What is being tested?
The trial is testing the safety and effectiveness of AZD9838 as a single-dose mRNA VLP vaccine for COVID-19 in adults who have previously been infected or vaccinated. It's compared to an existing licensed mRNA vaccine.
What are the potential side effects?
Potential side effects may include typical reactions to vaccines such as soreness at injection site, fever, fatigue, headache, muscle pain. Severe allergic reactions could occur but are rare.

Mechanism Of Action

Prior Approvals
Other Research
The most common treatments for COVID-19 include vaccines, antiviral drugs, and immune modulators. Vaccines like AZD9838 and AZD6563 work by introducing a component of the virus, such as the spike protein, to the immune system, prompting it to produce antibodies and activate T-cells that can recognize and fight the virus. This preemptive immune response is crucial for COVID-19 patients as it helps prevent severe illness by enabling the body to quickly and effectively combat the virus upon exposure. Antiviral drugs inhibit the replication of the virus within the host cells, while immune modulators help regulate the body's immune response to prevent excessive inflammation. Together, these treatments aim to reduce the severity and duration of the disease, ultimately improving patient outcomes.
