Vaccine Passport: Understanding the Digital Pass for International Travel and why world is opposing it?

Citizens in multiple countries are staging protests against the implementation of Vaccine Passport, a digital repository of your vaccination certifcate and other health documents for easy travel between countries. 

There have been very few global incidences that altered the functioning of the world and created as much havoc as COVID-19 did in the recent past. While almost every other industry faced a slump during the pandemic, the travel industry or more specifically aviation sector took a huge blow, so much so that experts are anticipating that we can only reach pre-pandemic levels of air travel by 2023. 

With almost all countries stopping international flights to contain the spread of the virus, and only a few allowing international travel even after 2 years of outbreak, there seems to be no respite for the industry to bounce back. 

There is, however, still a gleam of hope as many countries, independent agencies and airlines are looking for ways to make air travel easier and more accessible. One of the recent trends emerging globally is called the COVID-19 Passport or Vaccine Passport, which has been receiving flak off late from various countries and travellers.
