China gives its first COVID-19 vaccine approval to Sinopharm

No detailed efficacy data of the vaccine has been publicly released but its developer, Beijing Biological Products Institute, a unit of Sinopharm subsidiary China National Biotec Group (CNBG), said on Wednesday its vaccine was 79.34% effective in preventing people from developing the disease based on interim data.

China approved a COVID-19 vaccine developed by an affiliate of state-backed pharmaceutical giant Sinopharm on Thursday, its first approved shot for general public use as it braces for increased transmission risks over winter.

No detailed efficacy data of the vaccine has been publicly released but its developer, Beijing Biological Products Institute, a unit of Sinopharm subsidiary China National Biotec Group (CNBG), said on Wednesday its vaccine was 79.34% effective in preventing people from developing the disease based on interim data.

The approval comes after the United Arab Emirates this month became the first country to roll out the vaccine to the public.

While China has been slower than several other countries in approving COVID-19 vaccines, it has been inoculating its citizens for months with three different shots still undergoing late-stage trials.

China launched an emergency use programme in July aimed at essential workers and others at high risk of infection and as of the end of November, had administered 1.5 million doses using at least three different products - two developed by CNBG and one by Sinovac.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

While the efficacy of the Sinopharm shot trails the more than 90% success rate of rival vaccines from Pfizer Inc and its partner BioNTech and Moderna Inc, it points to progress China has made in the global race to develop successful COVID-19 vaccines.

The regulatory approval is a conditional, given to vaccines deemed urgently needed to cope with major public health emergencies even though complete clinical trials have yet to be completed, China's National Medical Products Administration said on Thursday.

The approval came as Britain on Wednesday approved a second COVID-19 vaccine, a shot developed by Oxford University and AstraZeneca, as it battles a major winter surge driven by a new variant of the virus.
