For example, how are 'flu vaccines approved each year? Is it because 'flu can be lethal in rare cases?
- danieltillett 9y agoThe reason flu vaccines are approved each year is they were first developed in the 1940s and we just keep using 1940s technology. If were to try to develop a flu vaccine today it would be impossible.
- mft_ 9y agoCan you point towards any further information on this, please? I'd like to read more.
