  The Coronavirus 2019 (Covid-19) pandemic caused by the SARS-CoV-2 virus
represents an unprecedented crisis for our planet. It is a bane of the \"uber
connected world that we live in that this virus has affected almost all
countries and caused mortality and economic upheaval at a scale whose effects
are going to be felt for generations to come. While we can all be buoyed at the
pace at which vaccines have been developed and brought to market, there are
still challenges ahead for all countries to get their populations vaccinated
equitably and effectively. This paper provides an overview of ongoing
immunization efforts in various countries. In this early draft, we have
identified a few key factors that we use to review different countries' current
COVID-19 immunization strategies and their strengths and draw conclusions so
that policymakers worldwide can learn from them. Our paper focuses on processes
related to vaccine approval, allocation and prioritization, distribution
strategies, population to vaccine ratio, vaccination governance, accessibility
and use of digital solutions, and government policies. The statistics and
numbers are dated as per the draft date [June 24th, 2021].
