the Vampire monster statblock states this for regeneration:

Regeneration. The vampire regains 20 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight or running water. If the vampire takes radiant damage or damage from holy water, this trait doesn't function at the start of the vampire's next turn.

The holy water item states this:

 If the target is a fiend or undead, it takes 2d6 radiant damage.

Under languages the Vampire statblock also mentions Languages the languages it knew in life, so does this mean that Vampires are raised from the dead like skeletons, zombies, and other undead? Sorry if this is more of a lore question

Yes, vampires are raised from the dead. In 5e a vampires bite attack, if used to kill a character, will cause the dead character to raise a vampire spawn the next night under the killing vampires control.

But a Vampire Spawn is not a vampire, they are different creatures

A vampire spawn is a vampire, it's a type of lesser vampire. Both vampires and vampire spawn are listed under the Vampire entry in the Monster Manual. The vampire spawn even has an attribute called "vampire weakness" and all its abilities say "the vampire", not "the vampire spawn"

 They are indeed different creatures, but they are both Undead, with the Spawn being simply an undead while the Vampire is an undead(shapechanger). By lore they are both Vampires, with the spawn being a lessor vampire created and enthralled by the greater vampire and as Dave said in the Stat block the Vampire spawn is referred to as a Vampire, possessing both the Vampiric weakness of it's progenator and it's regeneration as well. Eventually the Vampire spawn would mature into "normal" Vampire(I don't believe there is a mechanic  for this in 5e) You can also become a vampire magically though like Strahd. Which still requires the death of the person, much like any undeath transformation(Lich, Mummylord)

Born from Death. Most of a vampire’s victims become vampire spawn — ravenous creatures with a vampire’s hunger for blood, but under the control of the vampire that created them. If a true vampire allows a spawn to draw blood from its own body, the spawn transforms into a true vampire no longer under its master’s control. Few vampires are willing to relinquish their control in this manner. Vampire spawn become free-willed when their creator dies.

Vampires make Vampire Spawn. Vampire Spawn are controlled by the Vampire that made them unless that Vampire dies. Vampire Spawn can transform into Vampires if the Vampire they serve willingly chooses to let them draw their blood.

I forgot about that part of the entry in the MM, thank you Cyb3rM1nd.

It is literally all explained in the Vampire's description (which you need the MM to read) found past lair info.

OP does make an interesting point about holy water though. That is probably a relic from an older edition.

Didn't realize D&D beyond had this is you got the monster manual, tbh would be kinda nice if there was something saying 'more information available on this creature if you purchase the monster manual' below monster statblocks that have that. 

Without the monster manual on D&D beyond it just lists the Lair effects and then has the tags directly below that, with no indication that there is more information on the monster 

I think every monster except no name NPC stat blocks have descriptions. You had to have figured that the MM would contain descriptions for these monsters even if they weren't listed on the monster page itself.

I had assumed there was more information somewhere, but that could be in older versions books, the monster manual, volos/MToF, deep lore, etc. and I would be none the wiser. A lot of statblocks on D&D beyond have small description blocks from just the core rules, so I think just putting something along the lines of 'hey, there is more info on this creature that you can see if you get the monster manual' would be a nice QoL change. 

The end user shouldn't be making assumptions on if there is more content on something in another book that will become visible IMO

In DDB's defense, the monsters in the basic rules did not always used to get updated descriptions when you bought the MM. This feature was added later. And in order to have such a message, they would need to spend more time programming it in.

And fyi, all basic rules monsters (afaik) are from MM.

True, it would spend extra time to program, but I also think it would be a nice QoL feature, hence why I'm bringing it up in the feedback section of the forums
