The latest is that the DNA altering vaccine has side effects which are worse than the current flu vaccines. Add to that the requirement for a second dosage, of twice the first one, so, logically, either doubling the severe side effects of the first, or none at all, because you have "adapted", and unless you are howling at the moon, seaching out fire hydrants for that 2 AM potty call, and unexplainably calling everyone comrade, there is no reason to avoid the vaccine.
This is exactly why I got the vaccine asap, and nothing happened. No side effects,strange urges, or crotch sniffing. But you must excuse me now, Comrade, because I need to find a fire hydrant.
