The DCGI (Drugs Controller General of India) gave its go-ahead for the completion of its vaccine trials and the formal announcement about the intranasal vaccine is likely to be made in the next few days, according to sources. The nasal vaccine, BBV154 or Incovacc, had last month received a green signal from the Central Drugs Standard Control Organisation (CDSCO) under restricted use in an emergency situation for the 18+ population in India as heterologous booster doses.
