Background: SOBERANA 02 is a COVID19 conjugate vaccine (recombinant RBD conjugated to tetanus toxoid). Phase 1 and 2 clinical trials demonstrated its high immunogenicity, promoting neutralizing IgG and specific Tcell response. A third dose, of SOBERANA Plus (RBDdimer), further increased the specific anti RBD neutralizing antibodies. Methods: In a randomized, double-blind, placebo controlled, phase 3 trial (https://rpcec.sld.cu/trials/RPCEC00000354-En) we randomly assigned 44 031 participants, aged 19 to 80 years to three groups to receive a) two doses, SOBERANA 02, or b) two doses, SOBERANA 02 and a third dose, SOBERANA Plus, or c) placebo. Study endpoints are vaccine efficacy (VE) evaluated through confirmed symptomatic COVID-19 and safety. During the trial, the SARS CoV-2 isolates in Havana were 74.0 BETA;, shifting gradually to 100% DELTA; . Results: Two doses of SOBERANA 02 protected against symptomatic COVID-19: 43 cases in the two-dose group (14 371) vs. 155 in the placebo group (14 403), VE 71.0%, adjusted (CI 95%, 58.9 to 79.1). The heterologous three-dose combination increased the protection: 15 cases in the vaccine groups (13 833) vs. 155 in the placebo group (14 303), VE 92.4%, adjusted (CI 95%, 86.9 to 95.6%). For the two-dose schedule, VE against severe COVID-19 was 63.0% and for death, 59.0%; for the heterologous three-dose schedule, VE was 100% in both cases. Conclusions: This is the first phase-3 study of a three-dose, heterologous COVID-19 vaccine. Two doses of SOBERANA 02 were safe and attained efficacy of 71.0% in the adult population 19-80 y/o; incorporating SOBERANA Plus increased efficacy from 71.0 % to 92.4%.

The SARS-CoV-2 Delta variant is highly transmissible and contains mutations that confer partial immune escape. We compared RT-PCR cycle threshold (Ct) data from 699 test-positive anterior nasal swab specimens from fully vaccinated (n = 310) or unvaccinated (n=389) individuals. We observed low Ct values (<25) in 212 of 310 fully vaccinated (68%) and 246 of 389 (63%) unvaccinated individuals. Testing a subset of these low-Ct samples revealed infectious SARS- CoV-2 in 15 of 17 specimens (88%) from unvaccinated individuals and 37 of 39 (95%) from vaccinated people. To determine whether infectious virus titers differed in vaccinated and unvaccinated persons, we performed plaque assays on an additional set of 48 samples with Ct <25, finding no difference in infectious virus titer between groups.

There is an urgent need for animal models of COVID-19 to study immunopathogenesis and test therapeutic intervenes. In this study we showed that NSG mice engrafted with human lung (HL) tissue (NSG-L) could be infected efficiently by SARS-CoV-2, and that live virus capable of infecting Vero cells was found in the HL grafts and multiple organs from infected NSG-L mice. RNA-seq examination identified a series of differentially expressed genes, which are enriched in viral defense responses, chemotaxis, interferon stimulation, and pulmonary fibrosis between HL grafts from infected and control NSG-L mice. Furthermore, when infecting humanized mice with human immune system (HIS) and autologous HL grafts (HISL mice), the mice had bodyweight loss and hemorrhage and immune cell infiltration in HL grafts, which were not observed in immunodeficient NSG-L mice, indicating the development of anti-viral immune responses in these mice. In support of this possibility, the infected HISL mice showed bodyweight recovery and lack of detectable live virus at the later time. These results demonstrate that NSG-L and HISL mice are susceptible to SARS-CoV-2 infection, offering a useful in vivo model for studying SARS-CoV-2 infection and the associated immune response and immunopathology, and testing anti-SARS-CoV-2 therapies.

|

Human-to-animal spillover of SARS-CoV-2 virus has occurred in a wide range of animals, but thus far, the establishment of a new natural animal reservoir has not been detected. Here, we detected SARS-CoV-2 virus using rRT-PCR in 129 out of 360 (35.8%) free-ranging white-tailed deer (Odocoileus virginianus) from northeast Ohio (USA) sampled between January-March 2021. Deer in 6 locations were infected with at least 3 lineages of SARS-CoV-2 (B.1.2, B.1.596, B.1.582). The B.1.2 viruses, dominant in Ohio at the time, spilled over multiple times into deer populations in different locations. Deer-to-deer transmission may have occurred in three locations. The establishment of a natural reservoir of SARS-CoV-2 in white-tailed deer could facilitate divergent evolutionary trajectories and future spillback to humans, further complicating long-term COVID-19 control strategies.

The Coronavirus Disease (COVID-19) pandemic has brought significant impact onto the maritime activities worldwide, including disruption to global trade and supply chains. The ability to predict the evolution and duration of a COVID-19 outbreak on cargo vessels would inform a more nuanced response to the event and provide a more precise return-to-trade date. A SEIQ(H)R (Susceptibility-Exposed-Infected-Quarantine-(Hospitalisation)-Removed/Recovered) model is developed and fit-tested to simulate the transmission dynamics of COVID-19 on board cargo vessels of up to 60 crew. Due to specific living and working circumstances on board cargo vessels, instead of utilising the reproduction number, we consider the crew members from the same country to quantify the transmission of the disease. The performance of the model is verified using case studies based on data collected during COVID-19 outbreaks on three cargo vessels in Western Australia during 2020. The convergence between simulation results and the data verifies the performance of the model. The simulations show that the model can forecast the time taken for the transmission dynamics on each vessel to reach their equilibriums, providing informed predictions on the evolution of the outbreak, including hospitalisation rates and duration. The ability to model the evolution of an outbreak, both in duration and severity, is essential to predict outcomes and to plan for the best response strategy. At the same time, if offers a higher degree of certainty regarding the return to trade, which in turn is of significant importance to multiple stakeholders.

Introduction: As a result of the coronavirus disease 2019 (COVID-19) pandemic the year 2020 brought major changes on the delivery of health care and face to face physician patient communication was significantly reduced and the practice of remote telehealth care using computer technology is assuming a standard of care particularly with COVID-19 patients with attempts to reduce viral spread. Objective: To describe the clinical practice experience using telemedicine towards COVID-19 and the respective clinical outcomes. Methods: We performed a pilot open-label non- randomized controlled clinical trial. The patients were divided into four groups according severity of symptoms: (1) asymptomatic (2) mild symptoms (3) moderate symptoms and (4) severe symptoms and were followed up for five days counted from the beginning of the symptoms. A drug intervention was performed in group 3 for which the protocol followed as suggested by the International Pulmonology Societys consensus for adults with moderate symptoms: first day (attack phase) hydroxychloroquine sulfate 400 mg 12/12h second to fifth day (maintenance phase) 200 mg (half pill) 12/12h. The medication was associated with azithromycin 500mg once a day for five days. For children with moderate symptoms were used: hydroxychloroquine sulfate 6.5 mg/kg/dose every 12 hours in the first day and 3.25 mg/kg/dose every 12 hours from day 2 to 5. The therapeutic response was telemonitored. Group 4 patients were directly oriented to seek hospital care. During the use of the drugs, the patients were telemonitored daily. Results: One hundred eighty-seven patients were seen with mean age of 37,6 years (about 15,6). The most frequent symptom was cough (57,6%) followed by malaise (60,3%) fever (41,1%) headache (56,0%) muscle pain (51,1%). Of all the patients that sought telemedicine service in our center 23% were asymptomatic despite contact with people with probable diagnostic of COVID-19 29,4% reported mild symptoms 43,9% moderate symptoms and 3,7% severe symptoms. It was possible to observe in patients treated their symptoms of COVID-19 (group 3) with hydroxychloroquine and azithromycin for five days presented statistically better improvement of the symptoms when compared to those that did not follow the protocol (p = 0.039). Three patients were hospitalized and discharged after recovery. Conclusions: Our study showed that patients with COVID-19 who had delivery of health care through telemedicine initiated in early stages of the disease presented satisfactory clinical response, reducing the need of face-to-face consultations and hospitalizations. Our results indicate that the use of telemedicine with diagnosis and drug treatment protocols is a safe and effective strategy to reduce overload of health services and the exposure of healthcare providers and the general population to infected patients in a pandemic situation.

|

The impact of SARS-CoV-2 on the olfactory pathway was studied over several time points using Syrian golden hamsters. We found an incomplete recovery of the olfactory sensory neurons, prolonged activation of glial cells in the olfactory bulb, and a decrease in the density of dendritic spines within the hippocampus. These data may be useful for elucidating the mechanism underlying long-lasting olfactory dysfunction and cognitive impairment as a post-acute COVID-19 syndrome.

|

We recently published a preliminary assessment of the activity of a poly (ADP-ribose) polymerase (PARP) inhibitor, stenoparib, also known as 2X-121, which inhibits viral replication by affecting pathways of the host. Stenoparib is an inhibitor of mammalian poly (ADP-ribose) polymerases (PARPs). Here we show that stenoparib effectively inhibits additional SARS-CoV-2 variants, including an additional wild-type strain (Germany/BavPat1/2020), and the variants alpha (B.1.1.7), beta (B.1.351) and gamma (P.1) in vitro, with 50% effective concentration (EC50) estimates of 4.1 M, 8.5 M, 24.2 M and 13.6 M, respectively. A second study focusing on a combination of 10 M stenoparib and 0.5 {micro}M remdesivir resulted in over 90% inhibition of the alpha (B.1.1.7) variant, which is substantially greater than what was achieved with stenoparib or remdesivir alone at these concentrations.

|

There is an urgent need for potent and selective antivirals against SARS-CoV-2. Pfizer developed PF-07321332 (PF-332), a potent inhibitor of the main viral protease (Mpro, 3CLpro) that can be dosed orally; the compound is in clinical development. We demonstrate that PF-332 exerts equipotent in vitro activity against the four SARS-CoV-2 variants of concerns (VoC) and can completely arrest replication of the alpha variant in primary human airway epithelial cells grown at the air-liquid interface. Treatment of Syrian hamsters with PF-332 (250 mg/kg, twice daily) completely protected the animals against intranasal infection with the beta (B.1.351) and delta (B.1.617.2) SARS-CoV-2 variants. Moreover, treatment of SARS-CoV-2 (B.1.617.2) infected animals with PF-332 completely prevented transmission to untreated co-housed sentinels. The trough drug concentration at this efficacious dose were above the in vitro efficacious concentrations.

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) has led to significant public health, economic and social problems. Development of effective vaccines is still a priority to contain the virus and end the global pandemic. In this study, we reported that ReCOV, a recombinant trimeric NTD and RBD two-component SARS-CoV-2 subunit vaccine adjuvanted with BFA03 (an AS03-like squalene adjuvant), induced high levels of neutralizing antibodies against SARS-CoV-2 and the circulating variants in mice, rabbits and rhesus macaques. Notably, two-dose immunizations of ReCOV provided complete protection against challenge with SARS-CoV-2 in hACE2 transgenic mice and rhesus macaques, without observable antibody-dependent enhancement of infection. These results support further clinical development of ReCOV and the vaccine is currently being evaluated in a phase I clinical trial in New Zealand (NCT04818801).

We conducted pre-registered replications of 15 effects in the field of judgment and decision making (JDM). We aimed to test the generalizability of different classical and modern JDM effects, including, among others: less-is-better, anchoring, and framing to different languages, cultures, or current situations (COVID-19 pandemic). Replicated studies were selected and conducted by undergraduate psychology students enrolled in a decision-making course. Two hundred and two adult volunteers completed an online battery of replicated studies. With a classical significance criterion (p < .05), seven effects were successfully replicated (47%), five partially replicated (33%), and three did not replicate (20%). Even though research materials differed from the originals in several ways, the replication rate in our project is slightly above earlier reported findings in similar replication projects.

We present preliminary data in an ongoing observational study reporting SARS-CoV-2 spike protein reactive antibody levels from a convenience cohort of over 200 individuals in Kansas City. We observe stable antibody levels over a year in individuals who recovered from COVID19 infection caused by SARS-CoV-2. Our data revealed higher-than recovered levels from naïve individuals vaccinated with Pfizer or Moderna vaccines and similar-to recovered levels from Johnson & Johnson (J&J) recipients. For all vaccines, inoculation after recovery resulted in higher antibody levels than vaccination alone. Responses to Pfizer and Moderna vaccines decreased over time from high initial levels but at the time of publication remain higher than those for recovered or J&J recipients. Within our limited cohort we only see slight demographic trends including higher antibody levels in recovered female vs. male individuals. Booster doses and breakthrough infections both result in rapid increases in antibody levels.

It is well recognized that population heterogeneity plays an important role in the spread of epidemics. While individual variations in social activity are often assumed to be persistent, i.e., constant in time, here we discuss the consequences of dynamic heterogeneity. By integrating the stochastic dynamics of social activity into traditional epidemiological models, we demonstrate the emergence of a new long timescale governing the epidemic, in broad agreement with empirical data. Our Stochastic Social Activity model captures multiple features of real-life epidemics such as COVID-19, including prolonged plateaus and multiple waves, which are transiently suppressed due to the dynamic nature of social activity. The existence of a long timescale due to the interplay between epidemic and social dynamics provides a unifying picture of how a fast-paced epidemic typically will transition to an endemic state.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|

We show that the acceleration index, a novel yet simple indicator that measures acceleration of viral spread (Baunez et al., 2021), corrects the reproduction number for the time-varying amount of tests. Not doing so results in the reproduction number being a biased estimate of viral acceleration and we provide a formal decomposition of the resulting bias. When applied to French data for the COVID-19 pandemic (from May 13 to November 19, 2020), our decomposition shows that the reproduction number consistently underestimates the resurgence of the pandemic since the summer of 2020, compared to the acceleration index which accounts for the time-varying volume of tests. Because the acceleration index aggregates all the relevant information and captures in real time the sizable time variation featured by viral circulation, it is a sufficient statistic to track the pandemic9s propagation. As such it is a more accurate indicator to track the dynamics of an infectious disease outbreak in real time.

<li><strong>Protocol violations in López-Medina et al.: 38 switched ivermectin (IVM) and placebo doses, failure of blinding, widespread IVM sales OTC in Cali, and nearly identical AEs for the IVM and control groups</strong> -
|

<div>
|

A randomized controlled trial for treatment of mild cases of COVID-19 conducted in Cali, Colombia reported no statistically significant differences in outcomes for its ivermectin (IVM) and placebo arms. A striking anomaly, however, was that certain adverse events (AEs) that are distinctive for the study’s high-dose IVM use occurred at nearly identical rates in its IVM and placebo arms. The backdrop for these indicators of IVM use in study controls was widespread sales of IVM for COVID-19 in the Cali area during the study period, with 1.6 IVM doses sold over the counter for each case of COVID-19. The study compounded these risks of contamination of the control arm with critical errors in blinding and segregation of IVM v. placebo doses. A labeling error substituted IVM for placebo doses of 38 patients. Also, 5% dextrose solution was used for several weeks as a placebo, easily distinguishable from bitter tasting IVM. Given widespread availability and sales of IVM in Cali, lapses in segregation and blinding of IVM and control doses, and IVM-characteristic AEs in controls, the integrity of the study’s control arm was violated. Some useful information can nevertheless be salvaged from outcomes of this study’s IVM treatment arm, which had 0 deaths and generally mild symptoms, with AEs typical for high-dose IVM (replicated in the control group) that were generally mild and transient.
