I disagree with the post inside the article because it is logically flawed. The current approved crop did not have capacity to produce those vaccines either. MRNA did not have the facilities. It is mostly subcontracted. The reason that others are not producing any vaccine, is due to fact that they don't have it approved yet. There many contractors but not all countries have them.
The lesson in all this is for each country to produce their own vaccines and create facilities within their own countries and avoid being in mercy of superpowers' self interests and punish companies that ignored them during times of great need.
