Moderna and Pfizer vaccines produce up to 100 times more antibodies than Johnson & Johnson’s

A study conducted by scientists at Massachusetts General Hospital in the United States concluded that the two doses of Moderna and Pfizer’s vaccine against COVID-19 produce concentrations that are more than 100 times higher than the amount offered by Johnson & Johnson.

As highlighted by the Spanish media Infosalus, the research was carried out on a group of 215 healthy adults who had received at least one dose of the antidote a week before. Likewise, blood samples were also analyzed in a group of unvaccinated and uninfected adults with COVID-19; as well as other people who were in the process of recovering from the disease.

“We wanted to know how many antibodies against the spike are produced when each vaccine is received”, he pointed John Iafrate, lead author of the study.

This research, published in the journal ‘Journal of Infectious Diseases‘, also explains an analysis of the data on the efficacy of each vaccine as protection against cases of coronavirus contagion in people who have already received at least two doses of the aforementioned vaccines.

On the other hand, the results of the research were able to show that people fully recovered from the disease showed a level of antibodies similar to those who had received a single dose of the antidote of Modern and Pfizer; that were more than 10 times higher than the levels shown by the vaccine Johnson & Johnson.

The researchers also found that people who received the dose of Modern they had the lowest risk of getting a new infection. Compared to this antidote, those vaccinated with Pfizer were 1.53 times more likely to be infected with COVID-19; and 2.54 probabilities for those of Johnson & Johnson.

“Our data clearly indicate that a single dose of Johnson & Johnson results in a weaker antibody response than the other vaccination regimens. These findings certainly support the availability of booster vaccines for that population ”, remarked IAFR.

Analyzing the variants Beta, Delta and Gamma, found that Beta is the variant most likely to escape immune system surveillance. This indicates, according to Infosalus, that Delta and Gamma have other qualities, such as the ability to replicate rapidly, spreading throughout the world.
