    TED-Ed The title is not chosen very well... The health crisis already happend. She averted it from spreading to the US and more countries. But saying she averted it could come over belittling to the health crisis that already happened, if the word is interpreted wrongly. I would recommend «averted it from the US» or similar.

    A great deed by Kelsey, but to think that americans are 'protected' by the FDA is a bit strange. Because, with the new stringent requirements on drugs it would take longer and longer for beneficial drugs to be sold on the market. There are various estimates of how many die due medicine being available but illegal to prescribe to patients, but some suggests that prohibiting propranolol, a beta-blocker, may have resulted in the death of 30 to 280 thousand people; and maybe 80 thousand died from the prohibition of Septra, an antibiotic. See "Economics of Public Issues", pp 6-7.

    This was a really great video, very educational, but I would like to point out that at the end, while it was true back then, nowadays, women are unrepresented in stem fields not because they are accepted less, or paid less, but because they apply less, infact employers even prefer a female over an equally qualified male. There are probably social factors that affect this, yes, not not the points this video gave.

    I didn't really like personal commentary, at the end. You should put a name on it. Don't just imply it's that it's all men. That's just as bad as the claim you are making about them. Thumbs up, though. Whomever disliked this should have their head examined. What's not to like about healthy babies? Am I right?

    Loved it up until the end. Inspiring story. Nothing wrong with women choosing not to go into stem fields. Nothing wrong with men choosing not to go into nursing fields. Nothing wrong with men choosing not to get an education in psychology. Why do we care what field people focus on based on their gender?

    Why is nursing (including masters, NP, and PhD) ever-snubbed as a STEM field? Because it's already women-heavy. Include nursing in your STEM counts and you may see those numbers inch a little closer towards what we would like to see as far as 50/50

    I'm a college student. From my experience, women are only underrepresented in Engineering, Physics, Computer Science, and Philosophy... *Every* other major (from Chemistry to Sociology) has a good number of men and women. And women make up the majority in some majors. That said, I've seen sexist attitudes from people in majors that are mostly male or female.

    Dom VastaMonth ago

    But for every thalidomide blocked from the market, there are a dozen other drugs like beta blockers which are held up for months awaiting FDA approval, while patients who would otherwise be receiving the life saving treatment die. FDA approval should be required for advertisement and marketing of drugs, but not for their sale and use, let patients who would otherwise die take the risk to their safety into theirs and their doctor's own hands, allow them access to all the studies done on the drug, not just the ones that the pharmaceutical companies decided to send to the FDA, as well as access to the drug itself, while it is pending approval. No one should die when a cure for their illness exists, but a government body has yet to approve it.

    4:42 "Pervasive gender biases" NO! It wasn't gender bias that did that, it was money. You said it yourself earlier in the video!, it was a 2.24 billion dollar industry!, the company that sold the drug wanted in to that industry regardless of the risk to the public. They targeted her because she was the one most in charge of approving/rejecting the case!, not because of her gender, but because she was the one person in their way stopping them from getting their drug on the markets.

    To any young girls (or anyone for that matter) interested in science, there is this amazing book called "Women in Science" by Rachel Ignotofsky. It talks about the work of over 50 different female scientists from Roman times to the Space Race from all over the world. It's a fairly easy read and very detailed, and many of the women did these absolutely revolutionary things yet almost no one today will recognize their names. I recommend it to anyone.
