My guess is that these are possible outcomes with XXXX vaccine, so that's what they're using as a starting point.
And my other is guess is that a (very) small number of people developed XXX disease after vaccination. It might have be the cause, but correlation does not equal causation, ergo it's labelled as a possible side effect.
IANAD, but I did stay at a Holiday Inn Express.
