American multinational corporation, Johnson & Johnson ( J&J) has confirmed that they would begin with human trials of their potential Covid-19 vaccine by the second half of July. So far, there are about 10 coronavirus vaccines in human testing and experts have predicted that a safe and effective vaccine could take 12 to 18 months from the start of development.
J&J’s study will test the vaccine against a placebo and assess its safety and immune response in 1,045 healthy people aged 18 to 55 years, as well as those 65 years and older. The trial will take place in the US and Belgium. “Based on the strength of the preclinical data we have seen so far and interactions with the regulatory authorities, we have been able to further accelerate the clinical development,” said Paul Stoffels, J&J’s Chief Scientific Officer.
The corporation has already signed deals with the US government to create enough manufacturing capacity to produce more than 1-billion doses of its vaccine through 2021, even before it has evidence that it works but there are no approved treatments or vaccines for Covid-19.J&J’s is also in talks with the National Institutes of Allergy and Infectious Diseases to start larger, late-stage trials ahead of schedule, depending on results of the early studies and regulatory approval.
Moderna Inc is at the forefront of Covid-19 vaccine development and has started testing its candidate in a mid-stage trial that will enrol 600 patients. Moderna’s vaccine uses messenger RNA technology, an approach that has not yet been approved for any medicine, while J&J is using the same technology used to make its Ebola shot.
