Yeah, the information in the article is basically meaningless. It doesn’t matter how much the government gave Moderna if there’s no mention of the total development costs (which I have been unable to find the actual numbers for).
The article also confirms that the claim is wrong, but they take a super roundabout way of getting there. The claim was that $2.5b was the total cost of development, the truth is that the $2.5b was for both development and to purchase vaccines
Pretty much every drug developed in the US has some amount of government spending behind it, but that certainly doesn’t mean that the government pays for all of it or that the pharma companies don’t deserve to make a profit on their products.
