Johnson & Johnson begins final trial of COVID-19 vaccine

Pharmaceutical company Johnson & Johnson has started the final trials of its single-dose corona vaccine. Most pharmaceutical companies are testing a two-dose corona vaccine. Johnson & Johnson plans to conduct a vaccine test on 60,000 volunteers.

Scientist Dr. Paul Stoffel said, "Tests on 60,000 people will reveal the effect on different types of people. We are hoping that the results will be found at the end of this year or early next year."
