Pfizer
After searching and reading various articles, I have found the following. The Pfizer company sells Two-doses of the vaccine for $39 to the United States of America; meaning 1 single dose of Pfizer vaccine costs $19.5. As for the manufacturing price, the Pfizer company stated that it costs them $7.5 to manufacture one dose.
The agreement that was made with the USA stated that the US would buy 100 million doses of Pfizer for $1.95 billion, so one dose would cost $19.5. On the other hand, the EU is said to be paying $14.7 for the Pfizer vaccine, so it all depends on the contracts between the company and the country.
Oxford-AstraZeneca
The Oxford-AstraZeneca has a different price range. The graph below shows the cost of a single dose of this vaccine for each country.
Moderna
In August of 2020, Moderna said that it will be charging from $32 to $37 dollars per dose for some of its customers, so its price range is much higher than the other vaccines.
