Abstract

On 5 May 2023, the World Health Organization (WHO) officially declared the end of the coronavirus disease-19 (or COVID-19) pandemic. Even before the official announcement from the WHO, signs of recovery from the pandemic started appearing, especially after rapid worldwide vaccination. As society is getting back to its usual with each passing day, with the increasing socio-economic activities, discussion of the negative and positive outcomes of the COVID-19 pandemic remain the predominant topic of debate. Through this review, we discuss the bright side of the pandemic without undermining the pain and suffering everyone has gone through in this pandemic. The review also examined the painful side of the pandemic. Therefore, this review can be looked at as a comparison between this pandemic’s positive and negative effects. The review discussed aspects ranging from technological development, including mRNA-based vaccines, artificial intelligence-based screening, and telemedicine, to social behavior, from individual to global and from health to the environment. The review also examined the areas needing more attention for managing future pandemics. The review also highlighted what should be followed or continued for our preparedness for any possible pandemic. Toward the end, we also discussed how this pandemic has better prepared the world for future pandemics, as predicted by experts.

mRNA vaccines — a new era in vaccinology

Norbert Pardi, Michael Hogan, Frederick W. Porter … (2018)

mRNA vaccines represent a promising alternative to conventional vaccine approaches because of their high potency, capacity for rapid development and potential for low-cost manufacture and safe administration. However, their application has until recently been restricted by the instability and inefficient in vivo delivery of mRNA. Recent technological advances have now largely overcome these issues, and multiple mRNA vaccine platforms against infectious diseases and several types of cancer have demonstrated encouraging results in both animal models and humans. This Review provides a detailed overview of mRNA vaccines and considers future directions and challenges in advancing this promising vaccine platform to widespread therapeutic use.

Coronavirus biology and replication: implications for SARS-CoV-2

Philip V’kovski, Annika Kratzel, Silvio Steiner … (2020)

The SARS-CoV-2 pandemic and its unprecedented global societal and economic disruptive impact has marked the third zoonotic introduction of a highly pathogenic coronavirus into the human population. Although the previous coronavirus SARS-CoV and MERS-CoV epidemics raised awareness of the need for clinically available therapeutic or preventive interventions, to date, no treatments with proven efficacy are available. The development of effective intervention strategies relies on the knowledge of molecular and cellular mechanisms of coronavirus infections, which highlights the significance of studying virus–host interactions at the molecular level to identify targets for antiviral intervention and to elucidate critical viral and host determinants that are decisive for the development of severe disease. In this Review, we summarize the first discoveries that shape our current understanding of SARS-CoV-2 infection throughout the intracellular viral life cycle and relate that to our knowledge of coronavirus biology. The elucidation of similarities and differences between SARS-CoV-2 and other coronaviruses will support future preparedness and strategies to combat coronavirus infections.
