MRNA-1283 explained

Drug Name:mRNA-1283
Type:vaccine
Target:SARS-CoV-2
Vaccine Type:mrna
Tradename:Spikevax[1]
Routes Of Administration:Intramuscular

mRNA-1283 is a COVID-19 vaccine candidate developed by Moderna.

Compared to prior mRNA vaccines, this candidate has a storage temperature of 2-5 °C, compatible with vaccine storage in a standard refrigerator, rather than low temperature freezers.[2] Additionally, the vaccine will be packaged in prefilled syringes, reducing burden on healthcare workers and potentially increasing access.[3]

Clinical Trial

In December, Moderna started a clinical trial which would evaluate the vaccine's ability to provoke an immune response and its safety.[4] As of May 2024, the vaccine candidate is in Phase 3 clinical trials, with an estimated completion date of late August 2024.[5] Preliminary results from this trial indicated the vaccine produced a strong immune response, especially in patients over 65, who are at greater risk for severe outcomes from COVID-19.[6]
