Johnson & Johnson (NYSE:JNJ) has started a new late-stage study of its COVID-19 vaccine candidate which will enrol 6,000 people in the UK.

The studies follow positive interim results from an ongoing phase 1/2a clinical trials, which showed that the jab induced an immune response and was generally well-tolerated when injected once.
The pharma giant is looking to see whether two doses can protect patients for longer.
It will involve up to 30,000 participants worldwide in Belgium, Colombia, France, Germany, the Philippines, South Africa, Spain, the US, as well as the UK.
