Removing Roadblocks
Besides clearance on indemnity clause, foreign vaccine makers including Pfizer and Moderna had sought relaxation on the requirement for a post-approval bridging trial for its vaccine. Acting on the same, the Drugs Controller General of India (DCGI) on June 1 exempted foreign COVID-19 vaccines approved by specific nations or health bodies from post-approval bridging trials in the country. DCGI chief VG Somani said the decision to waive trials will only apply to the vaccines that have been approved for restricted use by the US FDA and other countries or which are listed on the WHO Emergency Use Listing (EUL).
'Bridging trials' are localised clinical trials which generate data related to the impact of foreign medicines/vaccines on the indigenous population before they are rolled out for the public. These trials are important in ascertaining the efficacy and potential side-effects related to the medicine/vaccine.
