How biotechnology is used in the production of vaccines?
For protein-based vaccines, the coding gene of the protein can be inserted into the plasmid and transformed into the host cell (e.g. E. coli or mammalian cells) which can then can express that gene into protein. The protein produced is then harvested, purified and formulated into vaccine..
How does biomedical engineering affect medicine?
Tools and Devices Bioengineers work together with other healthcare professionals, such as doctors, nurses, surgeons and technicians, to tackle health issues that they all come across. This has led to the creation of vital tools and devices such as MRI machines, dialysis machines, diagnostic equipment and ultrasound..
What are the benefits of biotechnology vaccines?
Advancements in biotechnology have made it possible to produce vaccines that cannot transmit a virus or bacterium. This method has helped create more than 20 new vaccines against infectious agents, improved existing vaccines, and increased the amount of vaccine that can be produced..
What is the role of biotechnology in vaccines?
The techniques of modern biotechnology such as genetical engineering and cell culture enable an effective, quick and economical development of vaccines. Recombinant DNA technology enables antigen of a certain pathogen to be produced in a host cell which is relatively non pathogenic (e.g. E..
All vaccines are genetically modified in a way. A gene may be programmed to produce an antiviral protein in a bacterial cell. Once sealed into the DNA, the bacteria is now effectively re-programmed to replicate this new antiviral protein.
Bioengineering techniques and materials have been used to synthesize several potent vaccines, approved or in trials, against coronavirus disease

Scientific work to develop a vaccine for COVID-19
SARS-CoV-2, the virus that causes COVID-19, was isolated in late 2019. Its genetic sequence was published on 11 January 2020, triggering an urgent international response to prepare for an outbreak and hasten the development of a preventive COVID-19 vaccine. Since 2020, vaccine development has been expedited via unprecedented collaboration in the multinational pharmaceutical industry and between governments. By June 2020, tens of billions of dollars were invested by corporations, governments, international health organizations, and university research groups to develop dozens of vaccine candidates and prepare for global vaccination programs to immunize against COVID‑19 infection. According to the Coalition for Epidemic Preparedness Innovations (CEPI), the geographic distribution of COVID‑19 vaccine development shows North American entities to have about 40% of the activity, compared to 30% in Asia and Australia, 26% in Europe, and a few projects in South America and Africa.
The Moderna COVID‑19 vaccine
RNA COVID-19 vaccine
The Moderna COVID‑19 vaccine, sold under the brand name Spikevax, is a COVID-19 vaccine developed by American company Moderna, the United States National Institute of Allergy and Infectious Diseases (NIAID), and the Biomedical Advanced Research and Development Authority (BARDA). Depending on the jurisdiction, it is authorized for use in people aged six months, twelve years, or eighteen years and older. It provides protection against COVID-19 which is caused by infection by the SARS-CoV-2 virus. It is designed to be administered as two or three 0.5 mL doses given by intramuscular injection at an interval of at least 28 days apart.
