Humoral response to the BBIBP-CorV vaccine over time in healthcare workers with or without exposure to SARS-CoV-2.

SARS-CoV-2-specific humoral response was analyzed over time in a group of healthcare workers with or without exposure to SARS-CoV-2, who underwent vaccination with BBIBP-CorV (Sinopharm) vaccine in Argentina. Seroconversion rates in unexposed subjects after the first and second doses were 40 % and 100 %, respectively, showing a significant increase in antibody concentrations from dose 1 to dose 2 (p < 0.0001). The highest antibody concentrations were found in younger subjects and women, remaining significantly associated in a multivariable linear regression model (p = 0.005). A single dose of the BBIBP-CorV vaccine induced a strong antibody response in individuals with prior SARS-CoV-2infection, while a second dose did not increase this response. A sharp increase in antibody concentrations was observed following SARS-CoV-2 infection in those participants who became infected after the first and second doses (p = 0.008). Individuals with SARS-CoV-2 exposure prior to vaccination showed significantly higher anti-spike IgG antibody levels, at all-time points, than those not exposed (p < 0.001). Higher antibody titers were induced by a single dose in previously SARS-CoV-2 infected individuals than those induced in naïve subjects by two doses of the vaccine (p < 0.0001). Three months after the second dose both groups showed a decline in antibody levels, being more abrupt in unexposed subjects. Overall, our results showed a trend towards lower antibody concentrations over time following BBIBP-CorV vaccination. Sex and age seem to influence the magnitude of the humoral response in unexposed subjects while the combination of exposure to SARS-CoV-2 plus vaccination, whatever the sequence of the events was, produced a sharp increase in antibody levels. Evaluation of the humoral responses over time and the analysis of the induction and persistence of memory B and T cell responses, are needed to assess long-term immune protection induced by BBIBP-CorV vaccine.

Resumen: La necesidad de distanciamiento social impuesta por la actual pandemia por coronavirus obligó a las diferentes sociedades científicas a realizar sus actividades en formato completamente virtual. La Sociedad Europea de Cardiología no ha sido la excepción. Desde el 29 de agosto al 1 de septiembre de 2020 se celebró este evento sin precedentes que, además de contar con 125.000 profesionales de 213 países, permitió el acceso gratuito a todos los cibernautas. De esta manera, la actualidad en cardiología pudo llegar a todos los rincones del mundo, pese a las circunstancias tan complejas. Como ya es tradición de la revista, realizamos un resumen de los principales ensayos presentados durante el congreso: - Early Rhythm-Control Therapy in Patients with Atrial Fibrillation (EAST-AFNET 4) - Cardiovascular and Renal Outcomes with Empagliflozin in Heart Failure (The EMPEROR-Reduced Trial Investigators) - Efficacy and Safety of Mavacamten in Adults with Symptomatic Obstructive Hypertrophic Cardiomyopathy (EXPLORER-HCM) - Angiotensin Receptor Neprilysin Inhibition Compared with Individualized Medical Therapy for Comorbidities in Patients with Heart Failure and Preserved Ejection Fraction (The PARALLAX Trial) - A Study to Evaluate the Effect of Dapagliflozin on Renal Outcomes and Cardiovascular Mortality in Patients with Chronic Kidney Disease (DAPA-CKD) - Aspirin with or without Clopidogrel after Transcatheter Aortic-Valve Implantation (POPULAR TAVI (Cohort A)) - Colchicine in Patients with Chronic Coronary Disease (The LoDoCo2 Trial Investigators) - Pharmacological Blood Pressure-Lowering for Primary and Secondary Prevention of Cardiovascular Disease Across Different Levels of Blood Pressure (BPLTTC) - Continuing versus suspending angiotensin-converting enzyme inhibitors and angiotensin receptor blockers: Impact on adverse outcomes in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (The BRACE CORONA Trial) - Randomized Trial of Transfusion Strategies in Patients with Myocardial Infarction and Anemia (REALITY Trial) Summary The need for social distancing imposed by the current coronavirus pandemic, forced the different scientific societies to carry out their activities in a completely virtual format.

Summary The SARS-CoV-2 pandemic has been a global challenge. In times of difficulty such as those that have recently arisen, research is even more necessary to advance in the diagnosis and treatment of different pathologies. Using the extensive development of the media, this year the American Congress of Cardiology was held from March 28 to 30 in a virtual format, allowing professionals from around the world to access multiple scientific activities with the same level of excellence as in face-to-face sessions. We will make a brief summary of some of the main scientific papers presented: - Tailored Antiplatelet Initiation to Lessen Outcomes Due to Decreased Clopidogrel Response after Percutaneous Coronary Intervention: TAILOR-PCI. - Rivaroxaban in Peripheral Artery Disease after Revascularization: VOYAGER PAD trial:. - Vericiguat in Patients with Heart Failure and Reduced Ejection Fraction: VICTORIA Study Group. - The Evolut Low Risk Bicuspid Study. - PARTNER 3.
