Presumably the fact that you're not allowed to drive around an give away the remaining doses like this is calculated to make doctors be more careful about when the open batches. After all, vaccination is not an emergency treatment, so it should be easy to avoid the situation in the article. If the rules were changed to allow for this, you can easily imagine that some less ethical doctors would decide to break seals just before closing the clinic, and then vaccinating their family and friends because "it would be a shame to waste it".
