Summary: This study formulates and analyzes an eight-dimensional ordinary differential equation model for COVID-19, taking into account the first and second dose of vaccination. The model is calibrated using the least-squares method and a global sensitivity analysis is performed to identify influential parameters. The results show that adhering to preventive measures and increasing vaccination rates significantly reduce the spread of the disease and the burden on the population.

Summary: A study was conducted to evaluate the safety and immunogenicity of a third dose of heterologous or homologous vaccines in Brazilian adults who had previously received two doses of CoronaVac. The results showed that a third dose of heterologous vaccines (recombinant adenoviral vectored vaccine or mRNA vaccine) significantly increased immune responses and could improve protection against infection.

Summary: The present study aimed to evaluate smell and taste functions in hospitalized COVID-19 patients and compare the results with a healthy control group. The study found a significant impairment of olfactory and gustatory functions in COVID-19 patients, with male patients suffering from more severe respiratory failure showing more evident gustatory and olfactory impairments.

Summary: This study examines the COVID-19 situation in Bangladesh and proposes a double-dose vaccination strategy to control the outbreak. Through qualitative analysis and numerical simulations, it is found that a full dose vaccination program can effectively reduce the number of cases and potentially eliminate the virus from the community.

Summary: The study showed that targeting the elderly population with high vaccine coverage is crucial, and focusing on the 20-39 and 40-59 age groups with at least 70% first-dose coverage by mid-June 2021 is necessary to minimize the risk of resurgence when lifting NPIs. An optimistic vaccination scenario with 70% coverage by mid-June and delaying reopening can significantly reduce case counts and severe outcomes by the end of 2021.

Summary: To achieve the goal of ceasing the spread of COVID-19 entirely, understanding the dynamical behavior of the virus proliferation is crucial. Mathematical modeling can provide a valuable and economical way to comprehend the key factors involved in the spread of the virus, especially when analyzing the impact of vaccination. In this article, a fractional order epidemic model is presented, and numerical methods are used to study and simulate the COVID-19 model. The results suggest that reducing the contact rate can decrease the number of cases if the population is not fully vaccinated, but increasing the vaccination rate is a better solution to reduce social distancing and lockdowns' negative impact.

Summary: This research investigates the relationship between the spread of COVID-19 and immigration policies, developing a mathematical model to simulate the spread of the disease under various immigration conditions. The results of the experiments demonstrate that increasing control measures on undocumented immigration across natural borders can effectively control the spread of the virus.

Summary: A mathematical model considering convalescent plasma transfusion (CPT) was developed to analyze the effects of different application rates on lowering the number of infectious individuals. Standard procedures in mathematical epidemiology were used to analyze the model, showing that the use of CPT resulted in a lower peak of infection cases and other epidemiological measures.

Summary: This study combines multiple models to predict the spread and consequences of COVID-19 cases, finding that non-pharmaceutical interventions have a greater impact on the epidemic evolution. Using a data-based model, different scenarios of vaccine rollouts and interventions are proposed to assess their impact on the pandemic.

Summary: Respiratory virus infections cause a significant global health problem, with different viruses varying in transmission modes and transmissibility. Understanding the relative contributions of different transmission modes is crucial for guiding the effectiveness of non-pharmaceutical interventions.

Summary: The study introduced two compartmental models to analyze individual behavior in spreading and controlling the COVID-19 epidemic. The comparison showed that the second model provided a better fit to the daily infected cases from Egypt, Belgium, Japan, Nigeria, Italy, and Germany. Furthermore, a vaccinated term was added to the model to predict how vaccination could control the epidemic.

Summary: A mathematical model was developed to analyze the COVID-19 transmission mechanism and the impact of therapeutic measures, showing globally stable disease-free and endemic equilibriums when R-0(v) is less or greater than unity. Findings also revealed the critical vaccination threshold dependent on vaccine efficacy and highlighted the most impactful parameters through sensitivity analysis.

Summary: After over a year into the COVID-19 pandemic, global deaths have surpassed two million, and while vaccines have shown progress, cases continue to rise with uncertainties around vaccine-induced and natural immunity. With vaccine supply shortages leading to delays in some countries, logistical, economic, and political factors present challenges in developing vaccination policies.

Summary: Most COVID-19 vaccines aim to induce immune responses, particularly neutralizing antibodies (NAbs), against the spike protein of the virus. mRNA vaccines have shown efficacy after just one dose, while adenovirus vaccines elicit polyfunctional antibodies and strong T cell responses. These findings suggest that protection may not solely rely on NAbs but also involve other immune effector mechanisms.
