"It's a lot better," Landau said of vaccinated immunity for the mRNA products. Companies that will want to say that their assays can correlate antibody measurements to neutralization assays will have to get their data together and file with the FDA to be authorized or approved to make those claims, he noted. At some point, the whole thing settles at a certain value, and only drops very slowly from there," Watzl says, adding that scientists are familiar with this phenomenon from other vaccinations.
