There is no cure for lycanthropy, and the only known way to combat the disease is by using wolfsbane potion, which does not prevent the transformation but does allow the drinker to mostly retain their human mind while in werewolf form. This effect therefore makes them much less dangerous to themselves and others. Unfortunately, this potion is extremely difficult even for accomplished wizards to brew, and since THE PROCLAMATION, it is classified as a controlled substance. Production and sale is monitored, requires a Ministry-issued license, and key ingredients are subject to tracking and regulation as well. All of this means that the price and demand of wolfsbane potion is at an all-time high and supply is at an all-time low.
Spells and physical wounds will hurt a transformed werewolf, but as werewolves heal quickly and are normally crazed, they are rarely slowed even by grave wounds. Most spells simply ricochet off their bodies, as with other magical creatures such as dragons and giants. Pure silver weapons can be used to kill a transformed werewolf, but when it comes down to it, your best strategy is to run like hell.
Werewolves retain memories of their transformed nights, but they may be jumbled and confused, as they were formed from the perspective of an animal. The transformation back to human form involves more accelerated healing. After even the most violent nights, the magic of lycanthropy will sustain the life of the afflicted person. The healing process often leaves bruises and scars and all sorts of aches and pains, but upon waking after a full moon, werewolves are in a rough but stable condition. Whether or not this is much of a blessing is up for debate, as many werewolves feel the healing simply means there is one fewer way out...
Fear, mistrust, and anti-werewolf sentiment is common, in large due to the two terrorist attacks on Hogsmeade that shook the magical community in June and September of 2015. The Ministry eventually declared that these attacks were perpetrated by werewolves who were attempting to make the long-rumored Underground Werewolf Society into a reality. This Society has never been more than a frightening urban legend, and consists of tales of werewolves who reject civilized life and live on the fringes of society, committing crimes and attacking whatever and whomever they wish. Their alleged mission is to turn as many wizards as possible into werewolves. Depending on which wizard you ask, though, you might instead hear that it's the Ministry who is terrorizing innocent werewolves...
Vampires can only properly digest blood, though they can consume water, alcohol, and a few other structurally simple, easy-to-digest liquids. The foods they once held generally don't appeal to them anymore, though many desperate baby vampires have certainly tried to eat a pizza anyway. Unfortunately, solid food and other complex substances pretty much go straight through them, and it's both painful and a bit gross. No one tries pizza twice.
A vampire cannot enter a human residence without being invited across the threshold by a resident, but one invitation is all they need to enter for as long as ownership of the residence remains the same. To the dismay of many, garlic and religious symbols have no negative effect on vampires. Despite rumors that vampires are unfeeling, they feel pain just as a human does. However, they do heal very rapidly following an injury, though more severe injuries take longer to heal. This same healing ability also prevents them from experiencing illness or carrying diseases. Former witches and wizards are still capable of performing magic with a wand, but per magical law, it is illegal for them to own one once they've been turned.
This sentiment has intensified since the dual terrorist attacks on Hogsmeade in 2015, and THE PROCLAMATION affected them negatively just as it did werewolves. Vampires are regulated via Beast Division and are now classified there as "non-wizard Dark creatures." This is a somewhat misleading title, because if a wix is turned into a vampire, they retain the magical power they had in life. Like werewolves, the Ministry of Magic requires them to be registered and to regularly report to their assigned Control Officer. Penalties for failing to register and relinquish one's wand are harsh: execution. Those in possession of wands are actively hunted by the Ministry of Magic, and vampires may also be tried and sentenced to death if they are caught consuming human blood.

Due to this inhospitable environment, vampires largely live in secret and band together in hidden places, such as the Bloody Mary, the only vampire pub in Britain since the early 1900s. This pub serves animal blood as well as alcohol, is one of the few places a vampire can find employment (of course, there are only so many jobs to go around), and even has a few rooms for vampires who need shelter from the daylight. Among vampires, the Bloody Mary is considered the (unbeating) heart of the vampire community.
To the mixed feelings of many, there is one group of vampires seeking to change things. The London Vampiric Society was founded in 1969 and is a collective of vampires campaigning for vampire rights. They are all "vegetarian" (i.e., consume only animal blood), all registered with the Ministry, all wandless, and are all at least somewhat sociable. Their aim as an organization is to attain some sense of equality (or at least dignity) for vampire kind. The ultimate goal of the LVS is to earn equal wand rights for vampires, and they do that by spreading their message and cleaning up the messes of less desirable vamps. Suspicion of and outright opposition to the group is voiced frequently in the media.
