hello @madridbg,
biochemistry is one of the areas of science that has contributed the most to the quality of life of human beings, thanks to this branch of science people can live longer, it is also true that the pharmaceutical industry abuses this branch of science by inventing diseases and then selling cures, but this does not imply that biochemistry is to blame, as you say, thanks to the foundations of this branch of science we can now have a vaccine to the pandemic.
