* Novavax jumps on $1.6 bln govt award for COVID-19 vaccine

* Energy companies slip on concerns over fuel demand

* Futures down: Dow 0.78%, S&P 0.65%, Nasdaq 0.31% (Adds quote, details; updates prices)

July 7 (Reuters) - Wall Street’s main indexes looked set to open lower on Tuesday following the benchmark S&P 500’s longest streak of gains this year as investors weighed the risks to the economy from tens of thousands of new coronavirus cases nationwide.

Florida’s greater Miami area became the latest U.S. coronavirus hot spot to roll back its reopening while Texas registered an all-time high in the number of people hospitalized at any one moment with COVID-19 for the eight straight day.

Energy stocks including Occidental Petroleum Corp and Concho Resources dropped about 2% on worries over fuel demand.

It looks like it will be a slight retracement of Monday and Thursday’s impressive gains, said Ryan Giannotto, director of research at GraniteShares ETFs in New York.

U.S. stocks have climbed despite an alarming rise in coronavirus cases as a surprise expansion in the U.S. service sector and a record job additions in June are among the slate of upbeat data recently that have bolstered views that an economic recovery is underway.

The benchmark S&P 500 and Nasdaq wrapped up five straight sessions of gains on Monday, with the latter closing at a record level.

The conundrum of growing cases and rising stock prices indicates that the liquidity from monetary stimulus is overriding fears over the immediate impact of coronavirus on the economy, Giannotto said.

At 8:10 a.m. ET, Dow e-minis were down 205 points, or 0.78%. S&P 500 e-minis were down 20.5 points, or 0.65% and Nasdaq 100 e-minis were down 33 points, or 0.31%.

Novavax Inc jumped 33.8% as the U.S. government awarded $1.6 billion to the drugmaker to cover testing, commercialization and manufacturing of a potential coronavirus vaccine in the United States.

Travel-related stocks, which were among the hardest hit during lockdowns, fell. United Airlines Holdings Inc and American Airlines Group Inc were down 2.6% and 2.3%, respectively.

Royal Caribbean Group and Norwegian Cruise Line Holdings Ltd also dropped about 1% each, even as they announced a joint task force to help develop safety standards for restarting their businesses. (Reporting by C Nivedita and Medha Singh in Bengaluru; Editing by Maju Samuel)
