The corona vaccine from the American pharmaceutical company Pfizer and the German biotech company BioNTech is, according to the two companies, more effective against the coronavirus than previously said.
The drug protects 95 percent and not 90 percent, as they said last week. Competitor Moderna reported on Monday that his medication is 94.5 percent effective.
Pfizer says it will be seeking permission to market the drug in the United States in the coming days.
The company used nearly 44,000 subjects to test the drug. One group received the candidate vaccine, the other group a placebo.
After vaccination, 170 people contracted the coronavirus, including 162 people in the control group with the placebo. Ten subjects developed serious complaints, one of whom had received the vaccine.
According to Pfizer, there were hardly any side effects; a small number was more tired than usual after vaccination.
