SÃO PAULO--Shares of Brazilian airlines Gol Linhas Aéreas Inteligentes SA and Azul Linhas Aéreas Brasileiras SA rose Tuesday, as did shares of aircraft maker Embraer SA, after concerns about an outbreak of Covid-19 in Brazil ebbed.

The full approval on Monday by the FDA of Pfizer's Covid-19 vaccine is also helping airline shares and Embraer today, according to Rafael Ribeiro, an analyst at the Clear Corretora brokerage.

"Airlines are up around the world because of the decline in worries about Covid in China," he said. "Pfizer got the approval for its vaccine, too and that's good for the whole air travel sector."

Shares of Gol were up 7.9% at 19.97 reais, the equivalent of $3.78, in late-morning trading. Shares of Azul were up 6% at 39.23 reais and shares of Embraer were up 6.8% at 22.34 reais.

China on Monday reported no new locally transmitted cases of Covid-19, the first day without new cases since July. The country imposed tough social distancing measures after an outbreak last month, sparking concerns about the impact on economic growth, and the news Monday indicates the measures are having an effect.

China is a major importer of Brazilian commodities including soybeans and iron ore, so the South American country's economy is heavily influenced by Chinese demand.
