What side effects are associated with this type of intervention?

The most common treatments for Norovirus are supportive care measures, as there are no specific antiviral drugs approved for this virus. However, mRNA-based vaccines, like those being studied in the trial mRNA-1403 and mRNA-1405, are designed to instruct cells to produce a protein that elicits an immune response. Known side effects of mRNA-based vaccines, similar to those observed with COVID-19 mRNA vaccines, include injection site pain, fatigue, headache, muscle pain, chills, fever, and nausea. These side effects are generally mild to moderate and resolve within a few days.

What prior FDA approvals exist?

As of now, there are no FDA-approved mRNA-based vaccines or treatments specifically for Norovirus. The mRNA-1403 and mRNA-1405 vaccines are currently under investigation to evaluate their safety, reactogenicity, and immunogenicity. These investigational vaccines work by instructing cells to produce a protein that elicits an immune response, a mechanism similar to the mRNA vaccines developed for COVID-19. Current treatments for Norovirus are primarily supportive, focusing on hydration and symptom management.

What other types of research exist?

As of 2024, promising novel alternatives to mRNA-1403 and mRNA-1405 for Norovirus treatment include other mRNA-based vaccines that are in advanced stages of clinical trials. Additionally, monoclonal antibody therapies, which have shown efficacy in preventing viral infections, could be considered. These treatments work by targeting specific proteins of the virus, thereby neutralizing it and preventing infection. Another innovative approach could be the use of viral vector-based vaccines, which use a different virus to deliver Norovirus antigens and elicit an immune response.

Summary

This trial tests the safety and immune response of two experimental mRNA vaccines, mRNA-1403 and mRNA-1405, in healthy adults. The vaccines help the body learn to fight a virus by giving it a practice run without causing illness.

Who is the study for?

Healthy adults aged 18-49 and 60-80 with a BMI of 18-39 kg/m^2 can join. Women must not be pregnant or breastfeeding and using effective contraception. Exclusions include bleeding disorders, acute illness, unstable medical conditions, immunosuppression, history of myocarditis/pericarditis, recent other vaccines or blood donations.

What is being tested?

The trial is testing mRNA vaccines (mRNA-1403 and mRNA-1405) against norovirus gastroenteritis in two age groups: young adults (18-49) and older adults (60-80). Participants will receive either the vaccine candidates or a placebo to assess safety and immune response.

What are the potential side effects?

Possible side effects may include local reactions at the injection site, feverish symptoms similar to mild flu-like symptoms, fatigue, headache, muscle pain. Severe allergic reactions are rare but possible.

Other Research

mRNA-based vaccines, such as mRNA-1403 and mRNA-1405, work by delivering messenger RNA (mRNA) into the body's cells, instructing them to produce a protein that is part of the Norovirus. This protein triggers the immune system to recognize and combat the actual virus if the person is exposed in the future. This mechanism is significant for Norovirus patients as it can help prevent infection or lessen the severity of symptoms, providing a proactive approach to managing the disease.
