According to an American preliminary study, Moderna vaccine is more effective to fight against the Covid-19 Delta variant than the Pfizer shot.

A study conducted by the Mayo Clinic – a famous College of Medicine and Science – states the Moderna vaccine is more effectively fighting against the Covid-19 Delta variant than Pfizer. This preliminary study has been conducted based on data from 50,000 patients vaccinated and not vaccinated between January and July 2021. It matches the period the Delta variant has taken over the previous variants.

This study – to be continued and peer-reviewed – has shows Moderna and Pfizer, the two mRNA vaccines, are working against the two main strains of Covid-19, but in a different way depending on situations. Against the Alpha variant, Pfizer reduces hospitalization risk by 85% and Moderna by 91.6%. Their effectiveness against infection and transmission reaches 76% for Pfizer and 86% for Moderna.

Already decreasing against the Alpha variant, Pfizer vaccine’s effectiveness is even lower against the Delta, actively spreading. Moderna vaccine is 76% effective against infection while Pfizer is “only42% effective.

And yet, Pfizer is the most injected vaccine, especially in France, with over 63 million doses injected out of 80 million.
