The study which was conducted by the US Centre for Disease Control and Prevention (CDC) said Moderna’s covid-19 vaccines are more effective against the Covid-19 Delta variant than the vaccines of Pfizer and Johnson & Johnson. Though it was mentioned that all the vaccines are effective at preventing hospitalisations and emergency department visits caused by the Delta variant and can be used in emergency.
They had analysed over 32,000 medical cases from different states during June-August 2021 and in that time the Delta variant was the predominant strain. In the results it was found that the unvaccinated individuals with covid-19 were more likely to need emergency care or hospitalisations.
The study in Morbidity and Mortality Weekly Report showed the difference between the effectiveness of the mRNA vaccines. During the study it was found that Moderna was 95% effective at preventing hospitalisations among adults ages 18 and older while Pfizer was 80% effective at preventing hospitalisations among adults aged 18 and older. Johnson & Johnson was only 60% effective in such cases.
The study author Shaun Grannis, Regenstrief Institute vice president for data and analytics and professor of medicine at Indiana University School of Medicine said, “These real-world data show that vaccines remain highly effective at reducing covid-19 related hospitalisations and emergency department visits, even in the presence of the new covid-19 variant."
He further added “We strongly recommend vaccinations for all who are eligible to reduce serious illness and ease the burden on our healthcare system."
