What is the purpose of this trial?

This trial examines the effectiveness of a new mRNA COVID-19 vaccine against both known and emerging variants of the virus. Participants will receive a shot of the mRNA-1273 Variant-containing Formulation to assess their immune response. Individuals who have already been vaccinated and may be at risk for severe COVID-19 could be suitable candidates. Interested participants should not have had a recent COVID-19 infection or received a vaccine shot too close to the trial's start. As a Phase 4 trial, this research aims to understand how the already FDA-approved and effective vaccine benefits a broader range of patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on systemic immunosuppressants or immune-modifying drugs, you may not be eligible to participate.

What is the safety track record for the mRNA-1273 variant-containing formulation?

Previous studies have shown that the mRNA-1273 vaccine, also known as Spikevax, is safe for people. Research indicates that this vaccine is generally well-tolerated, with most experiencing only mild side effects, such as sore arms or slight fevers, which resolve on their own. Serious side effects are rare. The vaccine's widespread use has generated extensive safety data, providing reassurance.

It is important to note that the mRNA-1273 vaccine is already approved for use in other COVID-19 vaccines, which adds confidence in its safety. While the new versions in this trial include variations of the original vaccine, they rely on the same proven technology. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about the mRNA-1273 variant-containing formulation because it offers a tailored approach to COVID-19 protection by incorporating new mRNA sequences designed to target emerging virus variants. Unlike existing vaccines that were developed based on the original strain of the virus, this treatment aims to provide broader and potentially more effective immunity against variants like mRNA-1273.167, mRNA-1273.712, and mRNA-1273.251. This adaptability may help enhance vaccine effectiveness and keep up with the virus's evolution, offering a significant advantage in controlling the pandemic.

What is the effectiveness track record for the mRNA-1273 variant-containing formulation against COVID-19?

Research has shown that the mRNA-1273 vaccine, also known as Spikevax, is highly effective at preventing COVID-19, achieving a 94.1% success rate in preventing illness, including severe cases. This vaccine has been widely used and has proven effective in real-world settings, not just in laboratories. In this trial, participants will receive an intramuscular injection of a variant-containing formulation of mRNA-1273 (mRNA-1273.167, mRNA-1273.712, or mRNA-1273.251) to test its effectiveness against new COVID-19 variants. The goal is to ensure it continues to protect people as the virus evolves. ^{2 3 4 6 7}

Published Research Related to This Trial

A booster dose of the mRNA-1273 COVID-19 vaccine significantly increased neutralizing antibody levels against the original virus and key variants of concern, indicating enhanced immune response after waning immunity from the initial two-dose series.

Both the mRNA-1273 booster and variant-modified boosters were found to be safe and well-tolerated, suggesting they could be effective options for improving protection against emerging SARS-CoV-2 variants.

Safety and immunogenicity of SARS-CoV-2 variant mRNA vaccine boosters in healthy adults: an interim analysis. Choi, A., Koch, M., Wu, K., et al.[2021]

The Moderna COVID-19 Vaccine (mRNA-1273) was developed using a proprietary mRNA platform and demonstrated high efficacy in preventing COVID-19 during clinical trials involving over 30,000 adults, starting with human studies in March 2020.

The vaccine received Emergency Use Authorization in December 2020 and full FDA approval in January 2022, indicating its safety and effectiveness based on interim and final analyses of trial data.

A booster dose of the mRNA vaccines BNT162b2 and mRNA-1273 significantly increases the durability of antibodies against SARS-CoV-2, providing enhanced long-term protection compared to the initial two-dose series.

Antibody levels after the mRNA-1273 booster were found to be higher than those after the BNT162b2 booster, indicating that the Moderna vaccine may offer superior antibody responses in the months following the booster.

In a study involving over 4 million participants, local and systemic reactions to the mRNA COVID-19 vaccines (BNT162b2 and mRNA-1273) were commonly reported, particularly after the second dose, with 72.9% experiencing injection-site reactions and 69.5% reporting systemic reactions after dose 2.

Younger individuals (under 45 years), females, and those receiving the mRNA-1273 vaccine reported higher rates of reactogenicity, but new or worsening symptoms were rare in the second week after vaccination.

In a study of 4,870,915 patients receiving the Moderna mRNA-1273 vaccine, approximately 85% completed their second dose on time, indicating strong adherence to vaccination recommendations.

However, only 51% of immunocompromised patients received the recommended third dose, highlighting a gap in vaccine completion that may require targeted interventions based on demographics and community characteristics.

The Moderna COVID-19 vaccine (mRNA-1273) was granted Emergency Use Authorization in December 2020 and has since been administered in approximately 204 million doses in the U.S., demonstrating its widespread use and acceptance as a primary vaccination method against COVID-19.

Following extensive review of clinical trial data and real-world effectiveness studies, the CDC concluded that the benefits of the Moderna vaccine in preventing COVID-19 infections and related hospitalizations significantly outweigh the associated risks, leading to its full approval for adults aged 18 and older.

The Moderna COVID-19 vaccine (mRNA-1273) has been found to have a favorable safety profile, with common adverse events like injection site pain, fatigue, and headache being transient and not significant enough to discourage vaccination.

However, there is a noted increased risk of myocarditis and pericarditis in young males aged 18-29, highlighting the need for ongoing monitoring and larger studies to fully understand rare adverse events.

In a phase 1 clinical trial involving 104 healthy adults, the mRNA-1283 vaccine was found to be safe, with no serious adverse events reported, indicating a favorable safety profile.

All doses of the mRNA-1283 vaccine (10, 30, and 100 µg) produced strong immune responses comparable to the established mRNA-1273 vaccine, suggesting its potential effectiveness in generating immunity against SARS-CoV-2.
