Centers for Disease Control and Prevention (CDC) in its study found the Moderna vaccine to be the most effective against Covid-19 hospitalization. It is reported by The Hill.

Researchers calculated Moderna’s vaccine effectiveness against hospitalization was 93 percent, while the effectiveness of the Pfizer-BioNTech and Johnson & Johnson vaccines was 88 percent and 71 percent, respectively.

“Although these real-world data suggest some variation in levels of protection by vaccine, all FDA-approved or authorized Covid-19 vaccines provide substantial protection against Covid-19 hospitalization,” the report said.

The study involved more than 3,600 adults who were hospitalized at 21 U.S. hospitals across 18 states between March 11 and Aug. 15. Out of those, 1,682 received positive Covid-19 test results, while the others were considered controls. Immunocompromised adults were not included in the research. 

Most of the participants — 64 percent — were unvaccinated. Almost 13 percent were fully vaccinated with the Moderna vaccine, 20 percent were fully vaccinated with the Pfizer shot and 3.1 percent were fully vaccinated with the Johnson & Johnson dose.Vaccine effectiveness among Moderna recipients hit 93 percent between 14 to 120 days after the second dose and dropped slightly to 92 percent after about four months. 

As we reported earlier, the Ministry of Healthcare of Ukraine allowed the combination of Moderna and Comirnaty/Pfizer-BioNTech vaccines. 

“If the first vaccination is given with Moderna vaccine, the second can be done with Comirnaty/Pfizer-BioNTech and vice versa,” the statement reads.
