if every field test of vaccine x shows it is 20% effective, the results are reliable. this has nothing to do with how effective the vaccine is. reliability is not a word i would use in describing any vaccine. if every field test of vaccine y shows it is 95% effective, the results are reliable. i also think that the more effective vaccine y would be described as better. if field tests of vaccine z show results of 60-90% effective, the results are unreliable, but vaccine z could be said to be better than vaccine x, assuming all other factors including side effects remain similar.

reliable has a totally different meaning in research. and totally dirrerent to effective. if a watch is always 10 minutes slow it is reliable as you can rely on it to be 10 slow. not accurate but reliable. my grandad had a reliable bladder, he always pee at 6am, problem was he didn't get up until 8. reliable is not always good.

the days of wasteful business lunches are over. by decree. the tonyaod post is 9 years ago, most of the thread is over 8 years old. having resurected an old thread, i wonder if we can expect a serving of spam?

how many aliases does this guy have?????????????? at least.

@lemon lover, if you don't let h im have the last word we will never get any peace.
