Sinopharm WIBP COVID-19 vaccine

Sinopharm WIBP COVID-19 vaccine is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sinopharm WIBP COVID-19 vaccine rather than just read about it. In short: The Sinopharm WIBP COVID-19 vaccine, also known as WIBP-CorV, is one of two inactivated virus COVID-19 vaccines developed by Sinopharm. Peer-reviewed results show that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases (26 cases in vaccinated group vs. 95 cases in placebo group).

Key takeaways

Sinopharm WIBP COVID-19 vaccine belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sinopharm WIBP COVID-19 vaccine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sinopharm WIBP COVID-19 vaccine from memory before moving on to harder problems.

Reference excerpt

The Sinopharm WIBP COVID-19 vaccine, also known as WIBP-CorV, is one of two inactivated virus COVID-19 vaccines developed by Sinopharm. Peer-reviewed results show that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases (26 cases in vaccinated group vs. 95 cases in placebo group). The other inactivated virus COVID-19 vaccine developed by Sinopharm is the BIBP vaccine (BBIBP-CorV) which is comparably more successful. 1 billion doses are expected to be produced per year.

Medical uses The vaccine is given by intramuscular injection. The administered is 2 doses in 3 weeks.

Efficacy In May 2021, peer-reviewed results published in JAMA of Phase III trials in United Arab Emirates and Bahrain showed that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases (26 cases in vaccinated group vs. 95 cases in placebo group). 12,743 people received the vaccine and 12,737 people received the placebo in these trials.

Manufacturing In June 2021, a new factory started production with the capacity to manufacture 1 billion doses annually.

History In April 2020, China approved clinical trials for a candidate COVID-19 vaccine developed by Sinopharm's Beijing Institute of Biological Products (BIBP) and the Wuhan Institute of Biological Products (WIBP). Both vaccines are chemically-inactivated whole virus vaccines for COVID-19. On August 13, 2020, the Wuhan Institute of Biological Products published interim results of its Phase I (96 adults) and Phase II (224 adults) clinical studies. The report noted the vaccine had a low rate of adverse reactions and demonstrated immunogenicity, but longer-term assessment of safety and efficacy would require Phase III trials.

Clinical trials In March 2021, Cayetano Heredia University running the BIBP and WIBP trials in Peru announced they were seeking to suspend and unblind participants in the WIBP trials for lower efficacy and offer the participants the BIBP vaccine instead, which was showing efficacy.

Authorizations

On February 25, 2021, China approved the vaccine for general use. According to The New York Times, the vaccine is only approved for limited use in United Arab Emirates. On August 19, 2021, the Philippines approved the vaccine for emergency use authorization.

Worked examples

Example 1 — a first encounter with Sinopharm WIBP COVID-19 vaccine

Start with the simplest possible case. Write down what Sinopharm WIBP COVID-19 vaccine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sinopharm WIBP COVID-19 vaccine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sinopharm WIBP COVID-19 vaccine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sinopharm WIBP COVID-19 vaccine

In research: Sinopharm WIBP COVID-19 vaccine appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sinopharm WIBP COVID-19 vaccine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sinopharm WIBP COVID-19 vaccine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese COVID-19 vaccines, Drugs not assigned an ATC code, Inactivated vaccines, so understanding it makes those chapters shorter.
In everyday life: Look for Sinopharm WIBP COVID-19 vaccine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
