Amid the new coronavirus (COVID-19) outbreak, many people especially, common man is thinking why medical scientist and healthcare researchers are taking too much time to develop the vaccine so, that people can be immune to protect from this disease.
Though, the clinical trial for new coronavirus is already under process globally, but the process of producing a usable coronavirus vaccine will take at least 12 to 18 months before make it available to the public at mass level for vaccination.
Coronavirus Vaccine Development Process
Actually, the process of testing and approving a new treatment or vaccine is a complex one, and for good reason. There needs to be safeguards in place to confirm that a treatment or vaccine is effective and safe before using it on the general public. It’s a painstaking process that involves sterilising every piece of equipment, from PCR plates to syringes, to ensure no cross-contamination. Results also take weeks, even months, to analyse, to ensure accuracy and reliability. To understand more, we’ve brought you the vaccine clinical trial and development process here:
CURRENT PHASE: RESEARCH & DISCOVERY
Currently, companies and labs around the world are working to identify and develop potential vaccine candidates and test them on animals to determine whether they’re promising and safe enough for human trials.
Once the vaccine has been proven to be successful and safe in animal testing, the FDA will approve it for human clinical trials. Some companies are already pushing to skip animal testing to accelerate the timeline to get to release, but many researchers are concerned about the risks of skipping this crucial step, let see the phases.
The first phase of the human clinical trial will involve giving the potential vaccine to a small group of healthy people (fewer than 100) and then monitoring those people for a few months for effectiveness and side effects.
This will help researchers understand the effect of the vaccine on the human body and whether there are harmful side effects that outweigh the benefits of the vaccine.
Once the vaccine passes the first phase, it will be approved for phase 2, which will involve a larger group of patients monitored over a longer period of time. Phase 2 clinical trials usually involve hundreds of patients and can take up to two years.
Due to the immediate nature of the pandemic and the fact that the vaccine is meant for the general population (and not a very specific subset of the population that could take a long time to recruit) this phase could be completed much faster than the normal timeframe.
Once the vaccine candidate is proven successful in the phase 2 trial, it will be approved for phase 3, in which the vaccine will be given to thousands of patients to gauge varying effectiveness and safety with different subsets of the population.
This will help ensure that the vaccine is truly effective for everyone and not just healthy and young members of the population.
FINAL PHASE: APPROVAL & RELEASE
Finally, the FDA will review the results of the clinical trials and approve the vaccine for the public. Then the company behind the vaccine can mass-produce the vaccine for public use and help them get immune with coronavirus infection.
The vaccine creator will still be required to run phase 4 trials after release to look for additional side effects and understand the long term effects of the vaccine once it’s out on the market. And at any time the vaccine can be taken off the market if necessary.
Even with an immediate global need, unlimited funding (it will take billions to shepherd vaccine candidates through the testing and approvals process), and collaboration from dozens of companies and governments, it will still take over a year before any vaccine will be available to control the COVID-19
Meanwhile, Australian researchers said they have mapped the immune responses from one of country’s first coronavirus patients, findings the health minister said were an important step in developing a vaccine and treatment.
Watch Video: The Race To Develop A Coronavirus Vaccine
While on the other hand, US volunteers test first vaccine for coronavirus and first human trial of a vaccine to protect against pandemic coronavirus has started in the US. But the biotechnology company behind the work, Moderna Therapeutics, says the vaccine has been made using a tried and tested process with more research.
Till now, none of vaccine is developed and not available in the market, you need to be very careful and stay protected from this virus with right preventive measures guided by designated medical authorities or health organizations.
