The American pharmaceutical company and its German partner have said they have begun testing their experimental coronavirus vaccine.
Pfizer Inc. and BioNTech SE Co. said in a statement that they have begun delivering their experimental Corona vaccine to the United States for initial human testing. In addition to the U.S. trials, there will be some 200 patients enrolled in trials in Germany.
The company says that if the vaccine proves safe and effective in trials, it could be widely shipped across the United States by the end of this year, ending years of conventional vaccine development.
Using Messenger RNA (mRNA) technology, the vaccine has the potential to become the first drug against the virus, which has infected more than one million people. Preliminary trials starting Monday include several versions of the vaccine. Companies will promote versions that look safest and offer the best immune response.
There is currently no approved treatment or certified vaccine for COVID-19, but some medicines are being used for Corona patients as a matter of urgency.
The U.S. research and testing is part of a broader global program that continues in Germany, where the biotech company was founded.
The U.S. company said last week that it hoped the U.S. Food and Drug Administration would urgently allow the trial vaccine by early October, after which it would be able to distribute more than 20 million doses by the end of this year.
Another vaccine developed by Invio based on DNA technology has also started US clinical trials. And clinical trials are expected to begin soon for candidates for vaccines developed by NovoVix and the University of Pittsburgh. Last month, trials of a vaccine from Oxford University began in the UK.
Johnson & Johnson, GSK, and Sanofi have also announced vaccine plans.
Experts from South Korea have claimed after a study that a patient infected with the deadliest coronavirus could not be infected again, following a suspicion that raised concerns. In South Korea, Japan, and China, people recovering from the corona are again falling victim to the virus.
Experts say that the second time in healthy people, the diagnosis of a deadly virus is the result of a testing error.
