Chronique de mes vacances en partie pourries par le passe sanitaire… Nous sommes partis le 23 juillet 2021 avec ma femme et ma fille cadette en direction de l’Auvergne où nous allions passer deux jours chez mes cousins dans le Haut-Cantal. Nous n’avions pas encore fait plus de dix kilomètres sur l’autoroute A10, que l’exploitant Vinci nous assenait d’un slogan lumineux, au sens propre, mais pas au sens figuré : « Tous vaccinés, Tous protégés ».

Background Immune protection following either vaccination or infection with SARS-CoV-2 decreases over time. Objective To determine the kinetics of SARS-CoV-2 IgG antibodies following administration of two doses of BNT162b2 vaccine, or SARS-CoV-2 infection in unvaccinated individuals. Methods Antibody titers were measured between January 31, 2021, and July 31, 2021 in two mutually exclusive groups: i) vaccinated individuals who received two doses of BNT162b2 vaccine and had no history of previous infection with COVID-19 and ii) SARS-CoV-2 convalescents who had not received the vaccine. Results A total of 2,653 individuals fully vaccinated by two doses of vaccine during the study period and 4,361 convalescent patients were included. Higher SARS-CoV-2 IgG antibody titers were observed in vaccinated individuals (median 1581 AU/mL IQR [533.8-5644.6]) after the second vaccination, than in convalescent individuals (median 355.3 AU/mL IQR [141.2-998.7]; p

The effectiveness of the two most widely used COVID-19 vaccines in the United States dropped significantly in July, a new study found. The efficacy of shots from Moderna and Pfizer were highly effective in preventing transmission of the CCP (Chinese Communist Party) virus, which causes COVID-19, between January and June, researchers with the Mayo Clinic and Massachusetts-based nference discovered. But the efficacy of Moderna’s … Read More »

TRIBUNE - Face à la propagande incessante des médias sur les morts du virus Covid-19 et la nécessaire et inévitable vaccination de la population pour enrayer l’épidémie, y compris des plus jeunes, il est désormais d’utilité publique de rappeler quelques chiffres et faits sourcés, afin que chaque citoyen puisse librement et posément décider pour lui et surtout pour ses enfants.
