I guess it depends on how you look at it. An automobile contains about 3 grams of platinum, mostly in the catalytic converter, but since the automaker is not in the business of mining metals, refining them, brokering them, or even necessarily manufacturing their own catalytic converters and spark plugs, you can't honestly say that large amounts of platinum were handled in the production of a car.
Similarly, a pharmaceutical company is not in the business of slaughtering animals or collecting blood donations, or even necessarily manufacturing their growth mediums and/or other vaccine components, so you can't honestly say that large amounts of blood are used in the production of an inactivated or live-attenuated vaccine.
The situation changes with post-exposure vaccines that contain gamma globulin, but even then, I don't think JW's have a problem with it (?)
