China Approves an mRNA Covid Vaccine, Its First
The
homegrown shot is a crucial tool that China has been lacking — a vaccine based
on a technology considered among the most effective the world has to offer.
China has for the first time
approved a Covid-19 vaccine based on mRNA technology, greenlighting a homegrown
shot months after the ruling Communist Party eliminated its strict pandemic restrictions.
China has long refused to use
the foreign-made mRNA shots that were crucial in easing the pandemic in many parts
of the world and that the United States first authorized for emergency use in December
2020. Beijing chose instead to promote its own pharmaceutical firms, first in rolling
out a more traditional but less effective Covid vaccine, and later, in the pursuit
of a homegrown mRNA, or messenger RNA, vaccine.
China’s new mRNA vaccine, developed
by CSPC Pharmaceutical Group Ltd., based in the northern Chinese city of Shijiazhuang,
was approved for emergency use by China’s health regulator, according to a
statement from the company on Wednesday (22.03.2023).
Among the vaccines currently
available in China, the most widely known are made by the companies Sinopharm and
Sinovac. Like other traditional vaccines, they rely on a century-old method for
inoculation, which use an inactivated virus to trigger a response by the immune
system, and have since proven to be less effective in protecting against symptomatic
disease.
The mRNA vaccines use a genetic
molecule that assists cells to make proteins that can set off an immune response
in the body. While new variants of Covid-19 are increasingly evasive to both traditional
and new vaccines, the mRNA technology allows scientists to quickly modify shots
to target the new strains.
The new Chinese vaccine comes
at a time when the party and its leader, Xi Jinping, are trying to jump-start an
economy that had been hurt by some of the harshest Covid-19 restrictions in the
world. This month, China reopened its borders to foreign travelers for the first
time since 2020, at the start of the pandemic.
For much of the pandemic, Chinese
residents lived under the country’s “zero Covid” policy, when unpredictable lockdowns
left tens of millions of residents unable to leave their homes for weeks at a time.
In major cities, P.C.R. testing was required every one to three days to enter any
public space.
The government’s efforts to eradicate
Covid were effective at keeping infections at bay, but they led to factory disruptions,
job losses and a plunge in consumer spending. The strict restrictions triggered
nationwide protests last November, the biggest challenge to Mr. Xi’s authority since
he became president in 2013.
China’s handling of the pandemic
has come under broader scrutiny as well, with the country facing renewed criticism
over its efforts to thwart investigations into the origins of the pandemic. Last
week, the World Health Organization accused Chinese officials of withholding research
that may link the virus’s origin to wild animals, asking why the data had not been
made available three years ago and why it has now disappeared.
With little warning, officials
ended the “zero Covid” policy in early December, removing mass testing booths and
pandemic protocols virtually overnight.
A Covid outbreak quickly swept
the country and overwhelmed ill-prepared hospitals, with deadly consequences. The
official death toll in China for the entire pandemic is around 83,000 people. Epidemiologists
widely believe the number to be a severe undercount, estimating the true toll to
be 1 million to 1.5 million people.
At the height of the Covid wave,
some mainland residents ventured across the border to the Chinese territory of Macau
to find foreign-made mRNA vaccines. During this time, China also began to
widely distribute Pfizer’s Paxlovid, an oral treatment found to significantly cut
the risk of hospitalization and death.
As Covid infections recede, many
Chinese residents have said they are eager to travel and resume their prepandemic
routines. Domestic tourism is booming, and subways in major cities are crowded with
commuters.
As of mid-March, the positivity
rate among P.C.R. tests in China was below 1 percent, down from a peak of 29.2 percent
in late December, according to Chinese government data. The figures have become
increasingly unreliable, as officials have stopped regular mass testing and made
reporting of home testing voluntary.
Developing its own mRNA shot
is a source of national pride and a boon for the Communist Party leadership. Creating
an mRNA vaccine from scratch is no small feat, experts have said. The first mRNA
shots developed for the virus were built on decades of research by scientists around
the world.
Early in the pandemic, China
shipped its vaccines to poorer countries around the world, hoping to use them as
a way to build allies and repair damaged diplomatic ties. The campaign, however,
lost momentum when officials in several countries raised doubts about the efficacy
of Chinese vaccines against more transmissible variants.
CSPC Pharmaceutical did not say
when the vaccine would be available to the public. Representatives for the company
did not immediately respond to requests for comment.
Until last summer, China seemed
to be on track to approve BioNTech, a German mRNA vaccine made in partnership with
Pfizer. Then it suddenly changed direction, all but abandoning the approval process
for BioNTech.
The delay in recognizing a foreign
mRNA vaccine appeared to be part of a deeply political exercise as the country has
turned more inward under Mr. Xi, who has encouraged Chinese companies to be self-reliant.
As the pandemic continued, China
also struggled to vaccinate its population, particularly its oldest residents.
At a news conference in November
just before the country’s Covid restrictions eased, Chinese health authorities said
that among people who were 80 and older, about 66 percent were fully vaccinated;
only 40 percent had a booster.
As the government pulled back
from the “zero Covid” policy, more residents appeared to get vaccinated. Nationwide,
about 91 percent have had their first two shots, according to the most recent data.
