An actual vaccine scandal
mRNA technology was just sitting on Big Pharma's shelf before massive public funding of a moonshot effort brought it into use.
Big Pharma prefers to spend cash on share buybacks and bonuses for executives.
Development efforts primarily go to anything that has huge monetary potential- tweaking cash cows to stay on patent and charge far more (insulin, epi-pens), a very expensive Alzheimer's drug of questionable efficacy, ransom drugs (is it really worth $100K to keep lung cancer patients alive an extra few months?) or obesity (well known to be treatable with diet and exercise).
They also spend money on ads threatening that if Dems cut the gravy train, you'll all die.
