Reply to comment by firstfrontiers in Is there any difference in efficacy when a vaccine is administered somewhere other than the upper arm (e.g. on the foot)? by MercurioLeCher

You didn't mention one very important thing: research. To reguster a drug, You need data backing it up, either as safe and effective or noninferior to another similar drug(which is to say, it's not less afe and efficient).

A new drug can be inferior in some ways, provided it is better in others. For instance, if it is a lot cheaper, has fewer side effects, targets a sub-group not covered by the comparison or more easily made available.

For instance, medications suitable for pregnant women are often inferior (less effective) that comparisons.

Anyway, words are fun. You can make them mean whatever you want.
