The race to analysis and produce COVID-19 vaccines on this planet is happening, with some have been initially commercialised and used for injection, similar to Pfizer (USA), AstraZeneca (UK-Sweden), Sputnik V (Russia) and Sinovac (China). Particularly, in Vietnam, with the dedication to hitch the world in learning vaccines to battle the pandemic, the Ministry of Science and Know-how has ordered Nanogen Pharmaceutical Biotechnology Joint Inventory Firm (Nanogen) to analysis and manufacture an area COVID-19 vaccine. After simply 5 months, with the very best spirit in sparing no efforts, boosting creativity and dashing up the analysis, Nanogen has efficiently produced its Nanocovax vaccine and put it into scientific trials. It takes time for the outcomes of the human trials, nevertheless, this success has affirmed the large scientific potential of Vietnam.
Many imagine that the preliminary success of Nanogen has “luck” in selecting the expertise of vaccine manufacturing, which is the recombinant protein expertise. Within the context that coronavirus has precipitated many harmful epidemics within the mankind historical past however no vaccine has been licenced for circulation, the selecting of expertise to develop vaccines is the most important problem for COVID-19 vaccine researchers and producers. Due to this fact, like “contact and go”, every nation chooses totally different applied sciences, similar to recombinant protein vaccines, nucleic acid vaccines (DNA and RNA vaccines), or inactivated vaccines. Vietnam, with a number of expertise in vaccine manufacturing, has by no means approached analysis on corona vaccines earlier than. Going through an pressing must analysis and manufacture vaccines in opposition to the COVID-19 epidemic, home models additionally adopted totally different analysis instructions on the idea of their strengths. Genomic sequencing confirmed that S protein and its elements encoded within the genome are the primary antigens that stimulate antibodies to neutralise the virus. On that foundation, the recombinant protein expertise by Nanogen Firm used a viral gene section that encodes S protein to specific on Chinese language hamster ovary cells to provide S protein, then harvested and purified it as uncooked a cloth for vaccine manufacturing. The vaccine is adsorbed into aluminium-containing adjuvants to reinforce the immune response. When vaccinated, the physique will create an immune response, the immune cells will bear in mind and once we are contaminated with the virus, the physique will rapidly recognise and produce antibodies to destroy the virus. Explaining this “luck”, Do Minh Si, Nanogen’s Analysis and Growth Director, mentioned that his firm has been mastering this expertise for over 10 years, so it solely takes about 5 to 6 months for them to introduce a candidate vaccine for preclinical and scientific analysis. With this expertise, Nanogen has had almost twenty years of analysis and manufacturing of medicine and bio-products to help most cancers therapy. Ho Nhan, the corporate’s Basic Director, has spent his complete life pursuing this expertise, since he was a scholar within the US.
That is additionally the primary time {that a} personal unit has stepped into vaccine analysis and manufacturing and has additionally proven its personal benefits. Trinh Thanh Hung, Deputy Head of Division of Science and Know-how for Financial-Technical Branches (below the Ministry of Science and Know-how – MOST), mentioned that within the battle in opposition to COVID-19, Nanogen has been assigned by the MOST to analysis and produce monoclonal antibody drug in opposition to COVID-19. With the momentum of almost profitable drug analysis, Ho Nhan made the daring choice to provide a vaccine, despite the fact that he knew it will be dangerous. Later, when the MOST and the Scientific Council chosen researchers and vaccine producers to order vaccine manufacturing, Nanogen gained the “plus factors” due to its analysis functionality, fashionable manufacturing line and nice dedication. Its monetary potential and fashionable tools has contributed to shortening analysis time to a file (usually it takes from 5-10 years from realizing the pathogen to the industrial vaccine). Many scientists admitted that in producing vaccine antigens, analysis institutes can do it, however to provide completed vaccines, there have to be a contemporary laboratory that meets the organic security requirements. Analysis funding totals VND28.6 billion (by which the State invests greater than VND8 billion), however in truth, the undertaking has value the corporate greater than VND200 billion, together with 100 staff working in laboratories.

An incredible benefit for home vaccine researchers and producers when accompanying the world in COVID-19 vaccine analysis is to instantly inherit, trade and share info and analysis outcomes with their friends to develop their very own merchandise. For instance, in 2002, when the coronavirus precipitated the SARS outbreak, the world took three to 5 months to deconstruct its genetic sequence. However now this course of is accomplished in just some days due to progress in gene sequencing expertise. These research are shared quickly throughout open databases, making them accessible to customers around the globe. Worldwide and Vietnamese analysis outcomes have contributed to shortening the analysis interval for Vietnamese vaccines. As well as, the MOST has shortened administrative procedures, in addition to connecting and activating all of the sources to concentrate on supporting Nanogen. The Nationwide Institute of Hygiene and Epidemiology – the place there’s a class 3 organic security cupboard – applied two of probably the most tough strategies that have been carried out for the primary time in Vietnam, together with a impartial response (injecting vaccine into mice to test whether or not mice produce antibodies to neutralise the virus or not) and problem take a look at (re-infecting mice with the SARS-CoV-2 virus after vaccination to test the protecting efficiency of the vaccine). The Nationwide Institute for Management of Vaccine and Biologicals shortened the procedures for testing the standard of the experimental vaccine, whereas the Vietnam Army Medical College centered on scientific trials. Problem assessments are normally carried out on monkeys within the organic security cupboards for animals in overseas nations, however since Vietnam doesn’t have this room, home scientists have taken benefit of organic security cupboard for virus tradition and creatively carried out assessments on hamsters – with monkey-like virus susceptibility and in small dimension, appropriate for laboratory circumstances.
Regardless of having a number of expertise in scientific trials for a lot of vaccines, whereas trusting preclinical take a look at outcomes and being prepared for the primary COVID-19 vaccine trials, Prof., Dr. Do Quyet, Director of the Vietnam Army Medical College, could not conceal his worries. Throughout a gathering of the grassroots Medical Ethics Committee of his academy, Quyet decided: “This take a look at is like taking a big gamble. If we do it properly, we are able to do many different issues sooner or later; in any other case we throw away all of the status of the Army Medical College, the Ministry of Well being and Nanogen Firm. Due to this fact, every member on this native degree council is required to advertise the very best sense of duty to finish the paperwork submitted to the Medical Ethics Council of the Ministry of Well being. If not, every will likely be personally accountable for any errors.” That assembly lasted from afternoon to night that day, with all council members and legal professionals turning over the circumstances on the volunteers becoming a member of the human trials many times to make sure their highest security in the course of the take a look at injection. Even the leaders and staff of Nanogen must “station” on the Army Medical College campus till the top of the trials. They must work with the very best spirit and most help, as a result of if the whole lot is momentary, the academy will certainly cease the testing. Lately, Prof, Dr. Quyet fortunately mentioned that volunteers got a second dose of fifty mcg of Nanocovax vaccine and had no negative effects or severe complexities, so it’s anticipated that by the top of 2021 there will likely be an official locally-made COVID-19 vaccine. Firstly of the scientific trials, Vietnam was one in every of 40 nations around the globe to have began scientific trials for COVID-19 vaccine. With the native manufacturing of diagnostic take a look at kits for SARS-CoV-2 and its first vaccine in opposition to COVID-19, Vietnam has joined “a spherical desk” with the world in a number of biomedical analysis fields. This preliminary success reveals that the “order” from the MOST for COVID-19 vaccine analysis and manufacturing is well timed and in accordance with the Occasion and State’s coverage of taking enterprise because the centre of innovation, whereas activating analysis institutes and administration businesses to concentrate on offering most help for companies.
Some marvel why Vietnam remains to be researching and producing its personal COVID-19 vaccines when many nations around the globe have already launched industrial COVID-19 vaccines. Consultants mentioned that because the world lacking out on additional analysis on the SARS vaccine has made us passive in opposition to the present COVID-19 epidemic. Moreover, the pandemic in not prone to disappear as rapidly because the Ebola or SARS epidemics, however will repeat once more, so the world is decided to have a expertise prepared for pandemic prevention. With that in thoughts, as one of many 42 nations on this planet that may produce vaccines and has a Nationwide Regulatory Authority (NRA) on vaccine high quality administration assembly the World Well being Organisation (WHO) requirements, Vietnam must be accountable with the world in combating in opposition to COVID-19. In the meantime, with out becoming a member of the world in COVID-19 vaccine analysis presently, it’s unimaginable to totally perceive the ideas of this vaccine, the vaccine’s interplay and the human immune system, from which providing options to manage different harmful illnesses that mankind will certainly face sooner or later. Due to this fact, different home vaccine producers in Vietnam are additionally making efforts to analysis and develop their very own COVID-19 vaccines, in the direction of scientific trials on people.
