COVID-19: State of the Vaccination

Abstract
The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting coronavirus disease 2019 (COVID-19) pandemic has led to rapid vaccine development and emergency use (EU) rollout. Six vaccines, including two using novel mRNA technology, are EU-listed by the World Health Organisation, and promising published trial data are available for nine more. While efficacy is good, there are various barriers to their global use. Long-term safety and immunogenicity data are being collected along the way.
