When I use this card's effect to digivolve it into a yellow Digimon card with the [Vaccine] trait in my security stack, can it digivolve regardless of its digivolution requirements?
No, this card's effect does not allow ignoring digivolution requirements, so you can only digivolve into a card that meets the digivolution requirements.

I have a Digimon in play with this card in its digivolution cards. [BT1-087 T.K. Takaishi]’s effect adds a yellow card from my security stack to my hand, and adds a card to my security stack. The number of cards in my security stack ultimately remained the same, but can I still gain 1 memory from this card’s inherited effect?
Yes. added a card to your security, so you gain 1 memory.

I used this card's [Start of Your Main Phase] effect to digivolve from a security card, then place a card from my hand at the bottom of the security stack. Do "when a card is added to the security stack" and "when a card is removed from the security stack" effects trigger simultaneously at such times?
Yes, they trigger simultaneously.
