Serum Institute of India and Bharat Biotech are expected to pursue late stage clinical trials of intranasal COVID-19 vaccines in the coming months once they receive regulatory approval, India’s health minister said on Sunday. Dr Harsh Vardhan said the late stage trial generally involves thousands of participants, sometimes 30,000 to 40,000. Of the vaccines currently in Phase 3 trials, all are administered by injection, according to the World Health Organization (WHO).
