Trial Details
The mRNA-1273-P305 clinical trial is evaluating the safety and immune response of the investigational mRNA-1273.529 booster vaccine that may protect against the COVID-19 Omicron variant. The investigational mRNA-1273.529 booster is being compared to a booster dose of Moderna’s COVID-19 vaccine, Spikevax, which is the vaccine that received conditional marketing authorization in the EU. All participants will receive either mRNA-1273.529 or Spikevax.
With different strains of COVID-19, there is an urgent need to develop vaccination plans that will provide greater protection. A booster vaccine that protects against COVID-19 variants, including the Omicron variant, would be a crucial public health tool to help curb the pandemic.
