‘Moderna Covid-19 vaccine neutralized titers against all key emerging variants tested, even the first identified variants in the UK and South Africa.’

However, the company also said it will test an additional booster dose of its Covid-19 vaccine (mRNA-1273) to study the ability to further increase neutralising titers against emerging strains beyond the existing primary vaccination series. ![twitter](https://images.medindia.net/icons/news/social/twitter.png)

Second, the company is advancing an emerging variant booster candidate (mRNA-1273.351) against the B.1.351 variant first identified in South Africa.
The company is advancing mRNA-1273.351 into preclinical studies and a Phase 1 study in the US to evaluate the immunological benefit of boosting with strain-specific spike proteins.
Moderna expects that its mRNA-based booster vaccine (whether mRNA-1273 or mRNA-1273.351) will be able to further boost neutralising titers in combination with all of the leading vaccine candidates.
"As we seek to defeat the Covid-19 virus, which has created a worldwide pandemic, we believe it is imperative to be proactive as the virus evolves. We are encouraged by these new data, which reinforce our confidence that the Moderna Covid-19 vaccine should be protective against these newly detected variants," Stephane Bancel, Chief Executive Officer of Moderna, said in a statement.
