The vaccine Modern It is the most effective against hospitalization for COVID-19, followed by that of Pfizer and the single-dose of Johnson & Johnson, according to a new study released this Friday by the Centers for Disease Control and Prevention of the United States (CDC, in English).

Specifically, it points out that Moderna’s effectiveness is 93%, Pfizer / BioNTech’s is 88%, and Johnson & Johnson’s is 71%.

“Although the data show some variation in vaccine protection levels, all approved or licensed vaccines offer substantial protection against COVID-19 hospitalization,” the CDC report said.

The study collects data from 3,600 adults who were hospitalized between March and August of this year in about twenty US states.

According to the researchers, the effectiveness of the Pfizer vaccine begins to decline more sharply than that of Moderna, and from the fourth month after its second dose has been administered, it stands at 77%.

One possible explanation is the period between the first and second doses, which in Moderna’s vaccine is four weeks and in Pfizer’s is three weeks, which would give more margin in Moderna’s case to strengthen antibodies, the CDC pointed out.

Pfizer and Moderna vaccines have a more sophisticated technology, since it is based on messenger RNA; while Johnson & Johnson’s is based on an adenovirus, like traditional vaccines.

This Friday is a meeting of the advisory committee of the US Food and Drug Administration (FDA) to decide whether to give the green light to a booster dose of Pfizer’s vaccine against COVID-19, as the Government of US President Joe Biden wants, despite the doubts on the part of the scientific community.

Currently, 63.5% of the US population over 12 years of age is vaccinated with the full regimen, and the rate of inoculation has slowed down in recent months, which has raised concern among health authorities about the rise in cases for the delta variant.
