Vabiotech COVID-19 vaccine

Vabiotech COVID-19 vaccine is a biology 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 Vabiotech COVID-19 vaccine rather than just read about it. In short: Vabiotech COVID-19 vaccine is a COVID-19 vaccine candidate developed by the Vaccine and Biological Production Company No. 1 (Vabiotech) in Vietnam. Clinical trials Preclinical In May 2020, Vietnam declared that their COVID-19 vaccine was developed after scientists successfully generated the novel coronavirus antigen in the lab.

Key takeaways

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

Reference excerpt

Vabiotech COVID-19 vaccine is a COVID-19 vaccine candidate developed by the Vaccine and Biological Production Company No. 1 (Vabiotech) in Vietnam.

Clinical trials

Preclinical In May 2020, Vietnam declared that their COVID-19 vaccine was developed after scientists successfully generated the novel coronavirus antigen in the lab. The vaccine has been developed by collaborating scientists at VABIOTECH in Hanoi and the Bristol University. It will be tested further in animals and evaluated for safety and effectiveness before a manufacturing process is embarked on. According to the National Institute of Hygiene and Epidemiology, it will take at least 12–18 months to develop vaccine that can work safely on human. During the testing phase, researchers experimented by injecting mice in many ways and administering multiple antigen doses, with some mice injected with one or two doses of 3-10 micrograms each. After 10 days, 50 mice were in good health and being closely monitored for immune responses. After gaining positive results with immune response and antibody production, the trial vaccine would be developed into a complete and stable version qualified to be used on humans. The research team would also develop commercial production procedures for mass-production, including up to tens of millions of units. In October 2020, the vaccine had been tested on 12 rhesus macaques (Macaca mulatta) in an island off the northern Quang Ninh province. The macaques are aged 3–5, weighing more than three kilograms each, and not infected with contagious diseases like tuberculosis or the HIV virus. Before being injected with the vaccine, they had their body temperatures, blood and swab samples taken and were kept separately in cages. They will be tested in two periods. In each period, they will be divided into two groups, with one being vaccinated and the other not. After that, they will be monitored daily on separate islands, before their blood samples are taken for further analysis. The testing will follow a similar model that maybe later performed on humans. The animals will be injected two shots of the vaccine, 18 to 21 days apart. A month after the second shot, researchers will assess the monkeys' immune response to see the difference between the injected group and the non-injected group. The result of these trials will be presented before the health ministry's ethical board within the following four months if experiments show the vaccine does produce effective immunogenicity and provide effective protection against COVID-19. It will be a foundation for the next stage for testing the vaccine on humans.

Worked examples

Example 1 — a first encounter with Vabiotech COVID-19 vaccine

Start with the simplest possible case. Write down what Vabiotech COVID-19 vaccine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Vabiotech 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 Vabiotech 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 Vabiotech COVID-19 vaccine

In research: Vabiotech COVID-19 vaccine appears in biology 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 Vabiotech 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: Vabiotech COVID-19 vaccine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clinical trials related to COVID-19, Protein subunit vaccines, Vietnamese COVID-19 vaccines, so understanding it makes those chapters shorter.
In everyday life: Look for Vabiotech 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.
