No organization has estimated the expenditure to vaccinate the entire world.
The pandemic has led to lockdowns announced in many countries to combat the spread of the virus. In turn, the lockdowns had left several unemployed people with no proper income source to fulfill their livelihood. However, despite the pandemic, the Amazon services owned by Jeff Bezos reaped huge profits. Jeff Bezos's real-time net worth as of Jan.10, 2021, is $185.7B, and he is the richest man in the world.
Vaccines are the mainstay in the fight against communicable diseases. The WHO and GAVI vaccine alliance was set up to provide poor and middle-income countries with diagnostic tests, drugs, and vaccines through a fund known as the Access to COVID-19 Tools (ACT) Accelerator. It is estimated that the total cost of the ACT Accelerator will be US$ 38 billion.
The cost of developing a vaccine from research and discovery to product registration and storage is estimated to be $1.5 billion. The high investment costs, along with the time horizon, will add up to the vaccine cost. But there is a paucity of explicit, publicly available cost data regarding vaccine development, manufacture, and delivery. A global budget and action plan does not exist, and therefore difficult to estimate the total vaccine cost.
Without a figure to compare, it's difficult to say whether Jeff Bezos is wealthy enough to vaccinate everyone in the world and still have money left.
