The news that the vaccine from the American company Moderna is 94.5 percent effective makes Joe Biden “hopeful”.
As with recent similar reports about the Pfizer vaccine, the incoming president of the US warns that it will take months before the drug can be used.
Until then, Americans must maintain their distance and wear face masks to get the virus under control, Biden continues to tweet.
In the US, contamination records are broken daily, and the country also has by far the highest number of deaths from Covid-19. Biden thanks the health care workers who are working “on the front lines” against the virus.
President Trump recalled on Twitter that the great vaccine discoveries were made during his term, addressing his message to “great historians.”
Earlier in the day he had called the presidential election the “most fraudulent” ever, without providing any evidence. “I won the election,” he tweeted again.
Moderna’s vaccine is 94.5 percent effective in preventing infection, according to preliminary research results, the pharmaceutical company reported Monday. Testing did not reveal significant safety issues. Competitor Pfizer previously said that its potential vaccine is 90 percent effective.
