Trump welcomes "good news" after Pfizer announced the effectiveness of its vaccine against "Corona"

Today, Monday, US President Donald Trump praised "good news" regarding the 90% effectiveness of a vaccine developed by the American companies Pfizer and German Biontech in preventing Covid-19 infection.

Minutes after the two companies announced the matter, Trump wrote on Twitter, "The stock market is going up, a vaccine is on the way soon. Reportedly 90% effective. Good news!" And that was days after he lost the presidential election to Democratic candidate Joe Biden.

Analysts attributed the Republican president's defeat in part to his administration's handling of the emerging corona virus crisis, especially with the spread of the epidemic throughout the United States recently.
