Moderna and the National Institutes of
Health quickly struck up work on a potential vaccine against the deadly
new coronavirus. But the team hasn’t found a pharma partner to
manufacture the vaccine for real-world use, a top official said Tuesday.
NIH and Moderna could develop a vaccine
in a little over a year if all goes well, but they wouldn’t be able to
produce the doses needed to deploy the shot against the
outbreak, National Institute of Allergy and Infectious Diseases director
Anthony Fauci said at an Aspen Institute panel. That’d require a pharma partner, and so far, NIH hasn’t found its manufacturer.
The virus has caused more than 45,000 infections and more than 1,100 deaths. The vast majority of cases have been in China.
If a pharma company were to get
involved, it would have to adjust manufacturing facilities and sacrifice
the “opportunity cost” of producing the profit-making shots it
typically makes, Fauci said at the panel. It’s a dynamic that’s “very
difficult and very frustrating,” he added.
Numerous times over the years, emerging
disease outbreaks have caught the scientific and medical community off
guard. Pharma companies and others have routinely rushed in on R&D
work, but outbreaks have tended to fade before the would-be vaccine
makers could develop effective countermeasures. Now, companies seem more
cautious about jumping right into the next new outbreak.
During the Ebola crisis, a major pharma
company “got burned” with its investment and is now backing out of the
field, Fauci said at the panel. That’s likely a reference to
GlaxoSmithKline, which bought NIH-partnered Okairos back in 2013 and
picked up Ebola vaccine candidates and several other pipeline programs.
Last year, the company exited Ebola vaccine research by licensing its
candidates to the Sabin Vaccine Institute.
Another top vaccine player, Sanofi,
got involved during the Zika outbreak, but its partnership with the U.S.
government led to a controversy over potential vaccine pricing. Sanofi
later exited the collaboration.
Despite the risk, Johnson &
Johnson said Tuesday it’s joining up with the U.S. Department of Health
and Human Services to accelerate vaccine development against COVID-19.
Both partners are chipping in funding to get the vaccine into the
clinic, and the government could provide more money for further
development.
Alongside the R&D effort, J&J
is readying production facilities so that it can “meet global health
needs” if the shot is deployed.
On the NIH/Moderna collaboration,
Fauci said the team should be able to get into the clinic in about two
and a half months from the time it received the initial virus sequence.
Then, he expects three months of testing in phase 1. If all goes well,
the team could advance to phase 2 testing in China that’d take six to
eight months.
After that, the group would be ready to
start producing vaccines for use in the field. Production would require
an amount of time that’s as “problematic” as developing the shot
itself, Fauci said. That’s unless the team produces vaccines “at-risk,”
or before getting proof the vaccine will even work.
