NEW DELHI, Feb 22 (Reuters) - Indian pharmaceutical
companies Bharat Biotech and Biological E. Ltd said on Monday
they could quickly rework their COVID-19 vaccine products to
fight new variants once their genetic sequence is known.
In recent months, India has confirmed the presence of the
variants first identified in Brazil, Britain and South Africa,
which are believed to explain an upsurge in cases in the Indian
states of Maharashtra and Kerala.
In all, India has reported more than 11 million coronavirus
infections, the highest number in the world after the United
States, and about 156,000 deaths.
"As we are seeing a lot of resurgence of cases, we are
picking up samples from hotspots and clusters and we are trying
to sequence them," Nivedita Gupta, deputy director-general of
the state-run Indian Council of Medical Research (ICMR), told
the BioAsia conference.
ICMR and Bharat Biotech have collaborated to develop India's
first homegrown COVID-19 vaccine, which, along with another
licensed from AstraZeneca and Oxford University, is
being used in the country's immunisation campaign that has
covered more than 10 million people since mid-January.
India is the world's biggest maker of vaccines, and its
companies have promised to produce billions of doses of COVID-19
shots.
Bharat Biotech Chairman Krishna Ella said his company would
mainly need data from the ICMR or the World Health Organization
on the genetic sequence of any variant to quickly make an
effective vaccine.
Speaking at a conference organised by the state of
Telangana, home to India's vaccine hub Hyderabad, Ella said a
product to tackle the South African variant could be made in 15
days and would not require any change to the manufacturing
process.
Biological E. Managing Director Mahima Datla said there was
no need to be "overly concerned" about the mutations.
"Eventually we don't know which variant of the virus, which
mutants will take over, but we think that it's prudent to work
on technologies that address the new variants as well," she
said.
Biological E., which is developing a vaccine with Houston's
Baylor College of Medicine and Dynavax Technologies,
recently completed Phase 1/2 clinical trial in India, Datla
said.
Its product uses the recombinant-protein technology in which
a harmless agent is used to stimulate an immune response in
cells.
"Once you know the variant, when it's sequenced, it is
fairly quick to deploy into a vaccine," said Datla, whose
company will also contract-manufacture Johnson & Johnson's
shot.
