ReviewImpact of COVID-19 on women and children and the need for a gendered approach in vaccine development.
The COVID-19 pandemic has imposed unprecedented health and socioeconomic challenges on public health, disrupting it on a global scale. Given that women and children are widely considered the most vulnerable in the times of emergency, whether in war or during a pandemic, the current pandemic has also severely disrupted access to reproductive and child health services. ⋯ In this context, we suggest the implementation of a gendered approach to ensure the specific needs of women and their newborns are considered during the development of COVID-19 vaccines. Taking into account gender-based biological differences, the inclusion of pregnant and lactating mothers in clinical trials for the development of COVID-19 vaccines is of vital importance.

ReviewSystemic innate and adaptive immune responses to SARS-CoV-2 as it relates to other coronaviruses.
The deadly pandemic caused by the novel coronavirus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) represents one of the greatest threats humanity has faced in the last century. Infection with this easily transmissible virus can run the gamut from asymptomatic to fatal, and the disease caused by SARS-CoV-2 has been termed Coronavirus Disease 2019 (COVID-19). What little research that has already been conducted implicates pathological responses by the immune system as the leading culprit responsible for much of the morbidity and mortality caused by COVID-19. In this review we will summarize what is currently known about the systemic immune response to SARS-CoV-2 and potential immunotherapeutic approaches.

ReviewGlobal scenario, public health concerns and mitigation strategies to counter current ongoing SARS-CoV-2 / COVID-19 pandemic.
Severe acute respiratory syndrome Coronavirus- 2 (SARS-CoV-2), the etiological agent of the novel coronavirus disease (COVID-19), has posed a great public health threat to the global community as a pandemic. The origin of the virus has been linked to animals, through a yet-to-be-identified intermediate host. The disease is transmitted to humans mainly through inhalation or contact with infected droplets. ⋯ There is an urgent need to strengthen One Health surveillance, intervention, and management strategies to understand the ecology of coronaviruses and to prevent epidemics in the future. Global attention toward the development of treatments, immunotherapies, vaccines, and control options to combat the COVID-19 pandemic has been on an increasing trend. Here, we review the current epidemiological status, public health concerns, and mitigation strategies for COVID-19.

ReviewRole of antibody-dependent enhancement (ADE) in the virulence of SARS-CoV-2 and its mitigation strategies for the development of vaccines and immunotherapies to counter COVID-19.
Coronavirus disease-2019 (COVID-19) pandemic has become a global threat and death tolls are increasing worldwide. The SARS-CoV-2 though shares similarities with SARS-CoV and MERS-CoV, immunopathology of the novel virus is not understood properly. ⋯ ADE mitigation strategies like the development of vaccine or immunotherapeutics targeting receptor binding motif can be designed to minimize ADE of SARS-CoV-2 since full-length protein-based approach can lead to ADE as reported in MERS-CoV. The present mini-review aims to address the phenomenon of ADE of SARS-CoV-2 through the lessons learned from SARS-CoV and MERS-CoV and ways to mitigate them so as to develop better vaccines and immunotherapeutics against SARS-CoV-2.

ReviewProspects for mucosal vaccine: shutting the door on SARS-CoV-2.
The sudden emergence of a highly transmissible and pathogenic coronavirus SARS-CoV-2 in December 2019 from China and its rapid global spread has posed an international health emergency. The rapid development of an effective vaccine is imperative to control the spread of SARS-CoV-2. ⋯ As evidenced by studies on similar coronaviruses (SARS-CoV and MERS-CoV), mucosal vaccination can provide a safe and effective means for the induction of long-lasting systemic and mucosal immunity to confer protection against SARS-CoV-2. This article summarizes the approaches to an effective mucosal vaccine formulation which can be a rewarding approach to combat the unprecedented threat posed by this emerging global pandemic.
