AstraZeneca and Johnson & Johnson are resuming their trials in the United States with the corona vaccines they have developed. As a precaution, the pharmaceutical companies temporarily halted the studies due to health problems in a few test subjects.
The British-Swedish pharmaceutical company AstraZeneca and the University of Oxford stopped their trials in early September but have now resumed them in the United States.
The trials in the United Kingdom, Japan, Brazil and India, among others, have already resumed at an earlier time. The clinical studies were discontinued after a UK subject became ill. According to the US authorities, there are no health hazards for the participants.
Johnson & Johnson’s trials in the United States were also halted due to the health of a subject. An independent committee has investigated the matter. The stroke a man would have had would not be related to the corona vaccine.
The Leiden vaccine maker Janssen, a subsidiary of Johnson & Johnson, is expected to resume tests in the United States on Monday or Tuesday.
Investigations of new drugs and vaccines are always discontinued as a precaution if an adverse reaction occurs during a clinical trial. This is followed by an examination to determine whether the problems are related to the vaccine.
