The new vaccine prevented 90% of infections in a study with tens of thousands of volunteers. This vaccine is being developed by two pharmaceutical and biotech companies in the United States and Germany.
The American pharmaceutical company Pfizer and the German biotechnology firm BioNTech have confirmed that their new coronavirus vaccine prevented 90% of infections in a study with tens of thousands of volunteers.
«The results are based on an interim analysis performed after 94 participants were divided into those who received a placebo and those who were vaccinated and infected with Covid-19, ”the report says.
Clinical trials of the vaccine will continue until 164 cases of successful prevention of infection are confirmed.
Pfizer hopes that this can be achieved in the coming weeks.
«This is the best news for the world, the United States and public health, ”said William Gruber, vice president of clinical research and vaccine development at Pfizer.
According to him, the new result even exceeds the most positive expectations of vaccine developers.
BioNTech confirmed that the effectiveness of the first vaccines was predicted in the range of 60% -70%, and more than 90% is somewhat «very unusual. “
