RW: how many FDA Approved drugs have been on the market for years and years only to be taken off the market due to dangerous and adverse effects
I asked this shaila from Rav Google and he said something like 35 out of 1500 approved (up to 2014).
I did not read carefully though, you may want to double check.
2020 Annals of Internal Medicine article ” Postmarketing safety of vaccines approved by the U.S. Food and Drug Administration. ” says there was 1 _vaccine_ recall out of 57 approved in 20 year window. it was within a year of approval. There were also 58 warnings for 25 of the vaccines related to immunocompromised and pre-existing conditions and allergies. Given that Pfizer might get full authorization in about a month, it probably has a similar safety profile.
