This is true for rich nations. In many poorer nations simple improvements to the healthcare system are far more realistic than creation of a new vaccine plant.

This is true for rich nations. In many poorer nations simple improvements to the healthcare system are far more realistic than creation of a new vaccine plant. mRNA vaccines are currently only produced by very few manufacturers, getting these vaccines to poorer nations is just not happening. In the mean time the vaccine will continue to mutate in these nations. The fact is many poorer nations lack basic equipment like oxygen generation units. This basically spells death for people who would otherwise recover. To put an example. Singapore has had 62K infections but only 32 deaths. Why? Its a small very rich nation. While there were large numbers warded in icu and requiring oxygen supplies, we had the equipment. By contrast anywhere else on earth we see far poorer survival rates.
