NEW YORK, Aug 23 (Reuters) - Wall Street rallied on Monday, and the Nasdaq reached an all-time closing high as sentiment was boosted by full FDA approval of a COVID-19 vaccine and market participants looked ahead to the Jackson Hole Symposium expected to convene later this week.

"This has been the script all along," said Peter Cardillo, chief market economist at Spartan Capital Securities in New York. "We make new highs, pull back, and then we’re off to the races again."
"That tells me the fundamentals are in place," Cardillo added. "There’s worries out there, but it’s hard to keep this market down."
The U.S. Food and Drug Administration (FDA) granted full approval to the COVID-19 vaccine developed by Pfizer Inc and BioNTech SE in a move that could accelerate inoculations in the United States.
"Full approval means that there’s most likely going to be more mandates, more companies will mandate that you have to get the vaccine in order to get back to the office," Cardillo said. "I don’t think this will get all the doubters vaccinated but this news today will probably drive (the vaccinated rate) closer to 75%."
Pfizer and U.S.-listed shares of BioNTech advanced 2.5% and 9.6%, respectively.
Rival Moderna Inc gained 7.5%.
