Gray was one of the experts who spoke at a Department of Health media briefing on Friday on the progress of government efforts in the fight against the pandemic.
She said healthcare workers have been asking if the J&J vaccine needs to be boosted.
"The answer is no. We don't need to boost just yet. This slide shows the tests we do in individuals who are in clinical trials and this is taken from participants who either got one shot or two shots of the J&J vaccine."
