J&J says in talks with Indian govt for trial of single-dose vaccine

Johnson & Johnson is in talks with India's government to begin a clinical trial of its single-dose COVID-19 vaccine in the country, the company said on Friday.

The U.S. drugs and healthcare giant's vaccine is currently approved for use in the United States, the European Union and other nations including Thailand and South Africa.

The news comes as some parts of India face a shortage of vaccine supplies just as the country of 1.3 billion battles a second wave of COVID-19 infections. India's government, however, has said there is no shortage of shots.

The Indian Express newspaper reported earlier on Friday that J&J had sent a letter to India's Central Drugs Standard Control Organisation (CDSCO) saying it would "very shortly apply for permission to conduct clinical bridging trials in India".

The CDSCO did not immediately respond to Reuters request for comment.

"We are in discussions with the (government) with the objective of starting a bridging clinical study of our Janssen COVID-19 vaccine candidate in India, subject to local regulatory approvals," a local J&J representative said via email.

A bridging study tests the safety and immunogenicity of a vaccine, and India has indicated that any vaccine maker must conduct such a trial for a shot to be considered for its immunisation programme.

Separately, J&J has a deal with Indian firm Biological E Ltd to contract-manufacture its vaccine.

India currently has two approved vaccines in use, one developed by Oxford University and AstraZeneca and the other, a shot from local player Bharat Biotech.

There are other vaccine candidates in trials in India including Russia's Sputnik-V and a shot developed by Cadila Healthcare Ltd.

COVID-19 infections in India rose by a record number for a third straight day on Friday, increasing by more than 130,000, while daily deaths hit their highest in five months.
