Repeated COVID booster shots Impair Immunity

This article discusses a study that showed that repeated injections of the recombinant COVID-19 “vaccines” lower the overall immune response. The study, Extended SARS-CoV-2 RBD booster vaccination, induces humoral and cellular immune tolerance in mice, was published in iScience in December 2022. Repeated Boosters Reduced Innate Immune Response The study shows repeated COVID shots (fourth dose)…

Natural immunity vs. Pfizer BNT162b2 vs. Coronavac

The study, Comparison of the immunogenicity of BNT162b2 and CoronaVac COVID-19 vaccines in Hong Kong, was published in the peer-reviewed journal Respirology. The two injections are different. The Pfizer BNT162b2  uses the modified RNA technology enclosed in a lipid nanoparticle. In contrast, the Coronavac uses an old vaccine technology using inactivated viruses that cannot replicate…
