You’re exactly right. Vaccines are not very profitable to begin with, couple that with the liability/malpractice angle, and nobody wants to make them anymore. That’s not really the fault of “Big Pharma”. Those with long memories (not me) will remember that the first iterations of the Polio vaccine in the 50s had problems. I recall that somebody in the line at Ft. Dix, New Jersey dropped out of the line at the innoculations during basic training. Always wondered, never saw him again.. It sucks, they made us all take the Anthrax shot. Was a pincushion prior to that even!!
That’s right - vaccines were not profitable so the drug companies did a cost benefit analysis - too many costs, not enough benefits. They then threatened not to invest any more time or money into research and development, so the government gives them certain protections. Imho, a better balance should have been achieved between public health concerns and drug company demands.
To channel Gordon Gecko (Wallstreet) “greed is good”. Greedy drug companies\\//greedy trial attorneys - in most instances the two balance one another out. A kind of yin/yang, lol.
