It has been shown that the antibody does not disappear for at least half a year if the vaccine for the novel coronavirus infection (Corona 19) of the US biotechnology company Modena is given.
An analysis of 33 healthy adults who participated in a phase 1 clinical trial of a corona 19 vaccine by US biotechnology company Modena showed that the antibody persisted for at least 6 months after two vaccinations, Bloomberg and AP reported on the 6th (local time). .
In addition to Modena, the results of this study, in which researchers at the National Institute of Allergy and Infectious Diseases (NIAID) and Emery University participated, were published in the International Journal of New England Journal of Medicine.
In a short study letter published in the journal, the researchers said, “Our data shows the persistence of antibodies,” and “thus, we support the use of this vaccine to counter the COVID-19 pandemic.”
These contents are similar to the test results of the previously announced Pfizer-Bioentech vaccine.
Pfizer and Bioentech announced on the 1st that an analysis of 46,307 participants in the phase 3 trial showed that it maintained a high preventive effect of 91.3% even after 6 months of vaccination.
However, Bloomberg News pointed out that Modena’s announcement that a small number of phase 1 test participants’ blood samples were analyzed in a laboratory, so it could not directly measure how long the vaccine’s preventive effect lasted in a real environment.
On the other hand, the New England Journal of Medicine on that day also published a report showing that, as a result of a study of 50 people who had been vaccinated with a Chinese-developed Sinopam or Sinobac vaccine, the efficacy was completely or partially lost against the South African variant virus The AP said.
