And US health officials this week publicly blamed the drug company for using “outdated information” when it estimated the vaccine was 79% effective.
The latest data was based on 190 infections among more than 32,400 participants in the US, Chile and Peru trial. And previous initial data indicated 141 injuries as of February 17.
Nevertheless, Maine Pangalos, executive vice president of research and development of biological drugs at AstraZeneca, said, “The basic analysis confirms that our Covid-19 vaccine is very effective in adults.”
These data come to confirm the decline of “AstraZeneca” in competition with the “Pfizer-Biontec” and “Moderna” vaccines, which recorded an effective rate of about 95%. Nevertheless, the “AstraZeneca” vaccine is considered vital in facing the spread of Corona, due to its ease of transport and its cheap price. It has been licensed for conditional marketing or emergency use in more than 70 countries.
And more than 12 countries have temporarily stopped using the “AstraZeneca” vaccine this month, after reports linking it to a rare blood clot in a number of people.
