Area of Science:
- Biotechnology
- Vaccinology
- Drug Delivery Systems
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, emerged in late 2019, leading to a global health crisis.
- Nucleic acids are increasingly recognized for their therapeutic potential across various diseases.
- Lipid nanoparticles (LNPs) have demonstrated significant promise for the effective delivery of nucleic acids, including mRNA.
Purpose of the Study:
- To explore the application of lipid nanoparticles (LNPs) in the development of mRNA vaccines.
- To highlight the role of LNPs in delivering mRNA for COVID-19 prevention.
Main Methods:
- Review of existing literature on LNP technology and mRNA vaccine development.
- Analysis of the formulation and delivery mechanisms of approved mRNA COVID-19 vaccines.
Main Results:
- LNPs are a key component in the successful development of mRNA vaccines like BNT162b2 and mRNA-1273.
- These LNP-based mRNA vaccines received emergency use authorization for preventing SARS-CoV-2 infection.
Conclusions:
- Lipid nanoparticles represent a vital platform for advancing mRNA vaccine technology.

Abstract:
Coronavirus disease (COVID-19) was first reported in December 2019, Hubei Province, China. As on 9th December 2021, severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has affected 266018810 people worldwide with 5265092 deaths. The outbreak of COVID-19 pandemic has caused severe public health crisis across the world. Nucleic acids have been emerging as potential drugs to treat a variety of diseases. Lipid nanoparticles (LNPs) have great potential to deliver nucleic acids including mRNAs. The two mRNA-based vaccines namely the BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) have been given emergency use authorization (EUA) by the US-FDA to prevent SARS-CoV-2 caused COVID-19 and the vaccines were developed using LNPs. This article focuses on the potential application of LNPs in the development and delivery of mRNA vaccines for COVID-19.
