* Wall St indexes rise following healthcare reform vote
* Euro rises vs dollar, though Greece uncertainty lingers
* Oil bounces off lowest since March 2 as dollar falls.

NEW YORK, March 22 (Reuters) - U.S. equities rose on Monday as passage of a landmark bill to reform healthcare drove up some big pharmaceutical stocks that will likely benefit from the bill, including shares of European drugmakers, while the euro rose against the dollar as risk appetite returned.
The euro, however, remained pressured by worries over Greece's ability to secure aid to help service its ballooning debts. Traders said the rebound would be short-lived as investors are expected to remain cautious ahead of a summit of European Union leaders on Thursday and Friday.
Oil rose toward $81 a barrel as Wall Street gained and the dollar came off earlier strength.
The firmer U.S. market reduced the loss in MSCI's all-country world stocks index <.MIWD00000PUS> to less than 0.1 percent.
The U.S. House of Representatives passed the healthcare reform legislation late on Sunday, and while analysts have raised concerns it will pinch corporate profits, they said much of the negative impact in stocks was priced in already. For details, see [
]"There's been a considerable amount of uncertainty in the healthcare arena surrounding the outcome of the legislation. The fact that we now have legislation removes that uncertainty, and it makes sense to get a bid under healthcare" stocks, said Kevin Caron, portfolio manager at Stifel, Nicolaus & Co in Florham Park, New Jersey.
Also, hospital and pharmaceutical companies could likely benefit from the bill.

GREEK FIRE
The euro earlier slumped to a three-week low against the dollar, pressured by uncertainty over aid for Greece, but later rebounded as rising equities markets revived risk appetite.
European leaders sent out conflicting signals over the weekend, with Germany urging Athens to solve its debt problems alone while Italy strongly backed EU support.
"It seems there's agreement there will be some sort of assistance to Greece, but it's not clear what form that will take," said Carl Hammer, currency strategist at SEB in Stockholm, adding that this would keep the euro under selling pressure. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The euro zone crisis in graphics: http://r.reuters.com/fyw72j Background graphic on Greek numbers: http://r.reuters.com/wax34j ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In early afternoon trade in New York, the euro was up 0.2 percent at $1.3553 <EUR=> after briefly touching a session high at $1.3568. Earlier the currency hit a three-week low at $1.3464. Traders cited short-covering as helping the euro after London trading wrapped up for the day.
The dollar declined against a basket of major trading-partner currencies, with the U.S. Dollar Index <.DXY> off 0.20 percent at 80.566.
Against the Japanese yen, the dollar <JPY=> slipped 0.53 percent to 90.05 yen.
Yields on benchmark euro zone government debt were lower as equities slipped. But the premium that investors demand to hold Greek government debt rather than euro zone benchmark Bunds rose to its widest since March 1. The cost of insuring Greek debt also rose.
Benchmark 10-year U.S. Treasury note <US10YT=RR> yields declined by 0.02 percentage point to 3.67 percent.
In energy and commodities, U.S. light sweet crude oil <CLc1> rose 17 cents, or 0.21 percent, to $80.85 per barrel. It had dropped as low as $78.57 earlier when the dollar was higher. Dollar-denominated oil and metals become more expensive for holders of other currencies when the dollar rises.
"Looks like commodities sold off on fear of what the equities would do after the health care bill passage. Since the apocalypse did not occur, I suppose the bulls feel it is safe to get long again," said Stephen Schork, president at the Schork Group in Villanova, Pennsylvania.
Spot gold prices <XAU=> fell $6.10, or 0.55 percent, to $1100.40. (Additional reporting by Dominic Lau and Naomi Tajitsu in London and Leah Schnurr and Caroline Valetkevitch in New York; Editing by Leslie Adler)
