Expect it to be expanded. Anyone that wants any "privileges" will have to get their cancer shots, and this means all hounders, assistant hounders, those who work behind the scenes doing things usually associated with assistant hounders, and pious-sneers will need them. Then, anyone will be deemed "weak" if they don't get their cancer shots, and eventually (I think within a year or so) it will be "you have 6 months to get fully vaccinated" for everyone. And anyone that falls behind in their booster shots will also face judicial committees. Meaning every 6 months.
Funny thing, they had the opposite stand about another thing that ruins your health--making cancer sticks stopping you from getting any position in headquarters, then stopping you from having "privileges", and then finally banning them altogether. The excuse was that your body belongs to the beady-eyed monster, and you are defiling it with those cancer sticks. True, you are ruining your body (not true that the beady-eyed monster thing has the right to own it) by smoking. But, taking those cancer shots is around 20 times more effective in defiling your body. Wouldn't it make sense that anyone that gets a cancer shot while baptized would be disfellowshipped instead of making those shots mandatory?
