Johnson & Johnson, one of the largest drug makers developing a vaccine against Covid-19, today began the process of applying for emergency approval of its vaccine from the European Medicines Agency and Health Canada.
In what's called a rolling submission, J&J's Janssen Pharmaceutical business sent regulators in the EU and Canada early testing data from its experimental one-dose vaccine for preventing Covid-19.
New Zealand has reached a deal for doses of the vaccine, subject to the approval processes.
Rolling submissions are used to speed up evaluation of crucial drugs by giving regulators data as it becomes available, and while human testing is still ongoing, rather than submitting reams of data at once after testing ends.
Johnson & Johnson said in a statement that the European Medicines Agency allowed the rolling submission mainly due to positive results from laboratory testing, which showed the vaccine triggered a robust immune response, creating antibodies that could fight the virus.
