FREESTATT? Uitleg en achtergronden: https://youtu.be/pEDfnz_Nzhc
De FREESTATT geeft individuen* de mogelijkheid te bieden om vrij te bewegen, veilig, niet te tracken, anoniem tijdens deze Coronacrisis.
Voor gezondheidszorg, onderwijs, openbaar vervoer, fabrieken, sport, vrije tijd.
De FREESTATT is een individueel digitaal certificaat, niet traceerbaar en gemakkelijk te gebruiken voor het individu en het ziekenhuis / werk / fabriek / school / stadion / winkel waar de persoon naar binnen wil.
Het is veilig in gebruik, niet reproduceerbaar en kan niet worden gehackt.
*Personen die zojuist negatief getest zijn, of die in de laatste maanden serologisch positief zijn getest. Tevens personen die volledig zijn gevaccineerd en daarna serologisch positief zijn getest ( met de kennis van april 2021 )
"Caution should be taken when relying on policies that requirelong-term immunity, such as vaccination or natural infection toreach herd immunity. Other studies have shown that neutralizingSARS-CoV-2 antibody levels decrease within the first 2 monthsafter infection, especially after mild COVID-197,8, and we observeda similar decrease in anti-nucleocapsid antibodies of seasonal coronaviruses (Extended Data Fig. 6). However, antibodies are only onemarker for immunity, which is probably also influenced by B cell- andT cell-mediated immunity. In our study, we monitored reinfections,which can occur only when protective immunity (cellular and/orhumoral) is insufficient. We show that reinfections by natural infection occur for all four seasonal coronaviruses, suggesting that it is acommon feature for all human coronaviruses, including SARS-CoV-2.Reinfections occurred most frequently at 12 months after infection,indicating that protective immunity is only short-lived"
