Wall Street closed slightly higher on Wednesday with the three major indexes managing their third straight day of gains after test data showed the COVID-19 vaccine from Pfizer and BioNTech offered some protection against the new Omicron variant.
Pfizer and BioNTech said their three-shot course of the vaccine was able to neutralize the Omicron variant in a laboratory test and they could deliver an upgraded vaccine in March 2022 if needed.
Investors reacted by piling into travel related stocks. The S&P 1500 Airlines index closed up 1.96%. Its session high was the highest since Nov. 24, which was just before news of the variant emerged.
Markets have been hugely volatile since the variant was discovered, with investors worried Omicron could force new restrictions in countries and hurt the global recovery.
In a bid to slow its spread, Britain said Wednesday it could implement tougher measures, including advice to work from home, as early as Thursday.
While Pfizer said Omicron protection was reduced among people who took just two doses of the vaccine, investors were still somewhat reassured.

"A lot is revolving around virus news. It's a reopening trade more than anything else," said Nolte.

The S&P finished less than a point below where it closed before a steep sell-off. The index fell as much as 4.4% between Nov. 24, the day before Thanksgiving, and Friday, as investors fled risky bets due to Omicron fears and concerns about rising interest rates after a Federal Reserve update last week.
