GSK, the world’s largest vaccine maker, laid out plans on Thursday to
produce 1 billion doses of vaccine efficacy boosters for COVID-19 shots
next year, as the race to develop a successful solution to the
coronavirus crisis heats up.
The British drugmaker said it was in talks with governments to back
the manufacturing expansion of the boosters, or adjuvants, that would
help to scale up production of future vaccines for COVID-19, the disease
caused by the novel coronavirus.
The adjuvant could be a critical ingredient in at least seven
experimental vaccines against the new coronavirus currently being
developed around the world, including one by Sanofi, with whom GSK signed a collaboration deal in April.
Adjuvants, a key component of the traditional vaccination approach,
have been shown to create stronger and longer-lasting immunity against
infections and allow for lower dosing of the protein in a vaccine,
making way for higher-volume production.
GSK would not disclose the programme’s costs, saying only that
production would take place at sites in Europe and North America and
that it would reinvest any profit into coronavirus research and
preparation for future pandemics.
The company is one of the many global players working on projects to
counter the respiratory illness that currently that has no treatment and
has killed about 350,000 people.
“We believe that more than one vaccine will be needed to address this
global pandemic and we are working with partners around the world to do
so,” said GSK Global Vaccines President Roger Connor.
As well as its collaboration with Sanofi, GSK has contributed the
adjuvant to alliances involving Chinese biotech firms Clover
Biopharmaceuticals and Xiamen Innovax, as well as the University of
Queensland, Australia.
GSK shares were up 1.4% at 1,671.2 pence by 0916 GMT.
BOOSTER SHOT
Experts have predicted that a successful vaccine will take more than a
year to develop. Companies and governments are pouring money into
dozens of programmes as their best hope of allowing an escape from
lockdowns and getting economies expanding again.
While more than 100 vaccine candidates are being trialled, according
to the World Health Organisation only 10 have moved to testing in
humans, a stage where they are investigated for safety and efficacy, and
at which most vaccines fail.

Other promising vaccine approaches do without adjuvants. These
include the use of so-called mRNA, pursued by Moderna and Biontech,
where genetic code is injected into the body to instruct human cells to
make virus-like proteins that trigger an immune response.
AstraZeneca
and Oxford University’s viral vector approach, where harmless viruses
instruct human cells to make virus-like proteins, also needs no
adjuvants.
The United States last week secured almost a third of the first 1
billion doses planned for AstraZeneca’s experimental COVID-19 vaccine by
pledging up to $1.2 billion.
On Thursday GSK said that making its adjuvant available to the world’s poorest countries will be a key part of its efforts.
