Quote by: RickSp Before putting preservative in vaccines, there were cases where the vaccine went bad due to bacterial contamination and dozens of children died. Vaccine was prepared in batches and could be dangerous without preservatives like thimerosol. These days vaccines are prepared in single unit dosages without thimerosal. This is more expensive but obviously preferable as long as you can afford it. |
Seems to me that ethanol would work just as well as a "preservative". Actually, what it's being used for is an antiseptic and high percentage ethanol is highly antiseptic. And, in the tiny doses that would be used in a vaccine, you might expect some very small children to get a bit lightheaded, but those doses would not in any way be harmful in the long term.
Seems a bit contrived to me to be using a mercury based antiseptic into the 1990s (and possibly beyond) when there are plenty of readily available, non-toxic antiseptics that could be substituted.
Just doesn't make any sense. (and on that note, I might go have myself a bit of ethanol.)
