The new trials of the vaccines will see volunteers receive aerosolised vaccines through a nebulizer, delivering the vaccine as airborne droplets through a mouthpiece.

On September 6, the standard review process triggered a voluntary pause to vaccination across all global trials to allow the review of safety data by independent committees, and worldwide regulators. All routine follow-up appointments continued as normal during this period.
Johnson & Johnson's JNJ.N Janssen unit will begin mid-stage trials of its COVID-19 vaccine in Spain on Monday, the programme's lead investigator said.
Brazil's health regulator Anvisa on Saturday said it had approved the resumption of tests of the "Oxford vaccine" in the South American country after receiving official information from AstraZeneca. Oxford University, where the vaccine was developed, said in a separate statement that the nature of the illness can not be revealed "for reasons of participant confidentiality". New platforms are providing the life sciences industry with an opportunity to improve the efficiency of clinical trials and reduce costs while remaining compliant and reducing risk.
Although Oxford would not disclose information about the patient's illness due to participant confidentiality, an AstraZeneca spokesman said earlier this week that a woman had developed neurological symptoms that prompted the pause.
The next steps on the vaccine trial would depend on details from the data safety monitoring board, she said, in a briefing before the MHRA had cleared the vaccine for trials.
"We are delighted that AstraZeneca has resumed its trials and continues to move forward".
"And only trials such as this will be able to tell us that".
The Serum Institute has partnered with five global pharmaceutical companies, including AstraZeneca and Novavax, to develop a coronavirus vaccine.
