Leading COVID-19 vaccine strategies in Phase III trials show promising results. Research examines viral vector, inactivated virus, protein subunit, and nucleic acid platforms for safety and efficacy against SARS-CoV-2.
Area of Science:
- Immunology
- Vaccinology
- Virology
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, necessitates rapid vaccine development.
- Multiple vaccine strategies are under investigation to combat the global health crisis.
Purpose of the Study:
- To review leading COVID-19 vaccine strategies currently in Phase III clinical trials.
- To examine preclinical and clinical trial data for various vaccine platforms.
Main Methods:
- Review of nonreplicating viral vector, inactivated virus, recombinant protein subunit, and nucleic acid vaccine platforms.
- Analysis of humoral and cellular immune responses, adjuvant effects, and potential risks like antibody-dependent enhancement.
Main Results:
- Promising advancements in the development of multiple SARS-CoV-2 vaccine candidates.
- Emerging Phase III trial data indicate encouraging protective efficacy and safety for frontrunning vaccines.
Conclusions:
- Several COVID-19 vaccine candidates demonstrate potential as effective tools against SARS-CoV-2.
- Continued research and clinical trials are crucial for identifying optimal vaccines.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
