A second CDC study, also published this Friday, indicates that Moderna’s vaccine is slightly more effective in preventing hospitalizations than the other two licensed in the United States: Pfizer-BioNTech and Johnson & Johnson ( Janssen).

The first of the studies was based on the analysis of more than 600,000 cases of COVID-19 in the United States between April and mid-July, announced the director of the CDC, Rochelle Walensky, during a press conference of the team against the pandemic of The White House: “Those who were not vaccinated were about four and a half times more likely to contract COVID-19, more than ten times more likely to be hospitalized and eleven times more likely to die from the disease,” explained Walensky.

The study reviewed infections, hospitalizations and deaths in thirteen states of the country in a period in which the delta variant, which now accounts for 99% of all COVID-19 cases in the United States, was already “the predominant variant that circulated in the country”. Walensky said the research “offers even more evidence of the power of vaccination” against COVID-19, at a time when about 25% of the US population who is eligible to get vaccinated are still reluctant to do so.

Moderna’s vaccine, a little more effective in preventing hospitalizations

As for the second study, on the effectiveness of each vaccine brand in preventing hospitalizations, it was based on the analysis of some 32,000 patients seen in hospitals, clinics and emergency departments of the country in nine US states. between June and early August.

Patients who had received the complete Moderna vaccine regimen were found to be 95% protected against hospitalization due to COVID-19, while in the case of those vaccinated with Pfizer that percentage was 80%, and in Johnson’s & Johnson, 60%. This conclusion is similar to that reached in August by another study by the Mayo Clinic health system, which has not yet been reviewed by other professionals but according to which Moderna’s vaccine was more effective in preventing infections of the variant. delta of COVID-19.

According to the study published this Friday by the CDC, Moderna’s vaccine is also more effective in avoiding visits to the emergency room of hospitals for covid-19 (92%), followed by Pfizer (77%) and Johnson & Johnson (65%).

The report does not explain why the advantage of Moderna’s vaccine is due, although some experts point to the fact that the mRNA dose of that injection is three times that of Pfizer, or to the longer interval between the first and the second. dose, The Washington Post reported.

53.3% of Americans have received the full schedule of covid-19 vaccines, including 62.4% of those over 12 years of age, according to the CDC.
