Trial Summary

What is the purpose of this trial?

This trial is testing a new flu vaccine called mRNA-1010 to see if it is safe and effective for people who need flu shots. The new vaccine uses a small piece of genetic material to help the body recognize and fight the flu virus.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on systemic immunosuppressants or certain immune therapies, you may need to stop them before joining the trial. It's best to discuss your specific medications with the trial team.

Is the mRNA-1010 vaccine for flu generally safe for humans?

Research on similar vaccines, like those for influenza and COVID-19, shows that most adverse events (unwanted effects) are known, non-serious, and occur shortly after vaccination. There have been no strong signals of unknown or serious adverse events in studies from Brazil and Denmark.12345

How is the mRNA-1010 vaccine different from other flu vaccines?

The mRNA-1010 vaccine is unique because it uses messenger RNA (mRNA) technology to stimulate an immune response against the flu, potentially offering a faster and more adaptable production process compared to traditional flu vaccines. It has shown to elicit higher immune responses for certain flu strains and is designed to be a quadrivalent vaccine, targeting multiple strains of the virus.678910

Eligibility Criteria

This trial is for healthy adults who can become pregnant but are not currently, using contraception or abstaining from pregnancy-causing activities. They must have a BMI of 18-<40 kg/m^2 (Part A only), no acute illness/fever before vaccination, and no history of severe allergies to mRNA or flu vaccines.

Inclusion Criteria

I am not pregnant, not breastfeeding, and will use birth control during and after the vaccine trial.
In Part A of the study, your BMI needs to be between 18 and less than 40. There is no BMI requirement for Part B.

Exclusion Criteria

You had a serious allergic reaction in the past after getting an mRNA or flu vaccine, or any of the ingredients in those vaccines, like egg protein.
I have used strong immune system suppressants for more than 2 weeks in the last 6 months.
Acutely ill or febrile (temperature ≥ 38.0°Celsius (C)/100.4° Fahrenheit (F) hours before or at the D1 vaccination visit. Participants meeting this criterion may be rescheduled within the 28-day screening window.

Findings from Research

In a study of 98 elderly individuals in Brazil, 84.7% of reported post-vaccination events were classified as non-severe, with local reactions being the most common (64.3%).
The findings highlight the importance of providing targeted information to healthcare providers to ensure safe vaccination practices and minimize avoidable adverse events in the elderly population.

During the 2009-2010 influenza A/H1N1v vaccination campaign in Denmark, 607 reports of adverse events were submitted, primarily involving non-serious reactions occurring within one day of vaccination, indicating a relatively low risk of serious side effects.
The study found no strong signals for unknown or serious adverse events linked to the vaccine, highlighting the safety of the influenza A/H1N1v vaccination during this period, although it also pointed out the limitations of relying solely on spontaneous reporting for assessing vaccine safety.

Cardiac complications, particularly myopericarditis, were the most frequently reported severe adverse events associated with mRNA COVID-19 vaccines, with systemic reactions being more common after the second dose.
Despite the higher number of reported adverse effects following the Pfizer vaccine, the review concluded that the overall benefits of mRNA vaccines in controlling the COVID-19 pandemic significantly outweigh the risks of adverse events.
