How the hell is Abbv growing so much? Is it still a buy near it’s 52 week high?

I currently own Pfe and I'm considering owning Abbv.

But it's insane for me how does Abbv has a 38,22% yearly and 18,82% montly growth while mantaining a pretty high dividend yield of 3,83% and a payout ratio of 80,62%.

The market cap at 264,50B vs the entreprise value at 331,35B shows a great debt.

The company valuation – 149,06$ is near the 52 week high – 151,25$ with all this international conflicts and inflation rise which is pretty impressive.

I'm wondering if it's still a buy and what do you think about it's future?
