Yes, but that rumour will now never go away, and the tin-foil-hatters will have more of a reason to claim "big pharma" is behind it all.
Instead of all this research into proving it's safe (which it already was, even with minimal bad side-effects, I mean, even anti-conception pills have side-effects, a minimal amount of negative side-effects would statistically be fine and not worth a fuss), I wish scientists around the world spent more time on how to properly convince vaccine-skeptics that it's safe AND a good idea to take part.
The biggest danger isn't the vaccines, it's people refusing to take them.
