Transmission & Prevention
· Where do we stand with the SARS-CoV-2 vaccines? In this extensive review, authors from Mangla Hospital & Research Center and Kumar Child Clinic in India detail the current state of promising COVID-19 vaccines. They present the current understanding of the immune response to SARS-CoV-2, including innate and humoral immunity, intensity and duration of response, and the applications this has for vaccines targets. They also point out practical limitations and possible conflicts regarding global vaccine distribution needed to achieve widescale herd immunity. The authors are hopeful as they outline current vaccines trials but acknowledge various issues that could prove problematic as the urge for an unprecedented turnaround time for a viable vaccine continues.
