The Moderna vaccine produces twice as many antibodies as the Pfizer / BioNTech vaccine, according to a study comparing immune responses after administration.
Particularly important findings about the two mRNA vaccines against coronavirus came from a recent US study, which was published in a letter to the Journal of the American Medical Association.
According to the study, the Moderna vaccine produces twice as many antibodies as the Pfizer / BioNTech vaccine, after a direct comparison of the immune responses after vaccination with these two drugs.
According to bloomberg, a study of about 2,500 workers in the Belgian hospital system found that antibody levels among people who were not infected with coronary artery disease before receiving the two doses of the Moderna vaccine averaged 2,881 units (per milliliter). ) compared to the 1,108 units in the group vaccinated with Pfizer.
The published results showed the differences, explaining them based on the following:
– Higher levels of active ingredient in the Moderna vaccine (100 micrograms compared to 30 micrograms in the Pfizer / BioNTech vaccine)
– Longer interval between two doses of Moderna (four weeks, instead of three in the case of Pfizer / BioNTech)
The Moderna vaccine was associated with a two-fold reduction in the risk of severe Covid-19 cases compared to the Pfizer vaccine, after examining individuals at the Mayo Clinic Medical Center in the United States from January to July. The results were recorded in a new study released before publication and evaluation on August 9th.
