Dr Robert Hess skepticism regarding the efficacy of all previous vaccines against the Delta variant has been confirmed by the announcement from BioNTech/Pfizer that they are working on a vaccine that will specifically target this mutant.

So far, we have been testing only one of the two immunity pillars, namely antibody production. In addition to checking the full range of antibodies, we at Salvagene go far beyond the generally applied classification to differentiate between the neutralizing antibodies and identify efficacy classes – low, medium and high – plus ADE antibodies which may even have the undesired effect of amplifying an infection. From now on, we will also be measuring the second Covid-19 immune pillar – namely T cell immunity – in great detail. For this purpose, we have upgraded our Covid-19 Immunization Program with the inclusion of the new SARS-CoV-2 T-Cell immunity analysis.
