ReviewCOVID-19 - Important considerations for developing and using a vaccine.
The novel coronavirus SARS-CoV-2 after emerging in China has caused a global pandemic that is risking the lives of millions. COVID-19 has spread across the world at a very rapid rate raising concerns of capacity limitations and lack of unified responses at the global level, particularly from the world's most developed countries. The spread of further infection has been curtailed by lockdown and mass social distancing that has been enforced in most parts of the world. ⋯ Extensive research is underway with some success in identification of monoclonal antibodies from COVID-19 recovered patients, which may inform on vaccine development. The clinical evaluations of COVID-19 vaccines need to follow standardized protocols that are essential for safeguarding humans. In absence of a vaccine or a widely available effective therapy, quarantine and other preventive measures are essential in curtailing the risk of pandemic spread.

ReviewVaccines and routine immunization strategies during the COVID-19 pandemic.
Severe acute respiratory syndrome coronavirus 2 related disease (COVID-19) is now responsible for one of the most challenging and concerning pandemics. By August 2020, there were almost 20 million confirmed cases worldwide and well over half-million deaths. Since there is still no effective treatment or vaccine, non-pharmaceutical interventions have been implemented in an attempt to contain the spread of the virus. ⋯ Numerous high-income as well as low- and middle-income countries are now experiencing a rapid decline in childhood immunization coverage rates. We will, inevitably, see serious consequences related to suboptimal control of vaccine-preventable diseases (VPDs) in children concurrent with or following the pandemic. Routine pediatric immunizations of individual children at clinics, mass vaccination campaigns, and surveillance for VPDs must continue as much as possible during pandemic.

LetterPreparatory phase for clinical trials of COVID-19 vaccine in Nepal.
Public health data suggested a rapid rise in COVID-19-confirmed cases in Nepal along with increased deaths. There has been a wide variation in clinical outcomes of this disease. Control of this pandemic depends on the availability of vaccines or drugs for SARS-CoV-2. Thus, viral and human genetics/genomics and immunology are necessary to understand whether these factors will affect clinical trials of vaccines in Nepal.

ReviewConvalescent plasma therapy for coronavirus infection: experience from MERS and application in COVID-19.
The emergence of the COVID-19 pandemic has resulted in a very large number of infections and high number of mortality. There is no specific therapeutic options that are approved for clinical use. Administration of convalescent plasma as a possible therapy was used in the case of viral pneumonia including SARS and influenza. ⋯ Two of these studies used plasma with anti-SARS-CoV-2 titers of >1:640 to >1:1000. A recent randomized controlled clinical trial showed no benefit of convalescent plasma in patients with severe diseases. However, the study was terminated early and thus further clinical trials are needed to show efficacy in patients with COVID-19 infection.

ReviewCOVID-19 - Recent advancements in identifying novel vaccine candidates and current status of upcoming SARS-CoV-2 vaccines.
The COVID-19 pandemic caused by SARS-CoV-2 has spread rapidly. To date, countries have relied on the prevention of the disease through isolation, quarantine, and clinical care of affected individuals. ⋯ There also is a need to comprehensively compile the details of previous studies on SARS-related vaccines that can be extrapolated to identify potent vaccine targets for developing COVID-19 vaccines. This review aims to analyze previous studies, current status, and future possibilities for producing SARS-CoV-2 vaccines.
