Ever since the SARS-Cov-2 was declared a pandemic by World Health Organization (WHO), health institutions worldwide are doing their best to develop the vaccine of the life-threatening virus. However, the development of a vaccine – for any disease – is not that easy; it requires years of research, testing, and a hundred percent assurance before reaching the clinics.

That being said, 2020 has been quite uncertain year. With the death rate pushing ahead faster than ever due to the coronavirus, scientists were practically racing each other to develop the safest and the most effective vaccine for coronavirus. As a result of this race, more than seventy vaccines reached the clinical trial from all around the world. Researchers tested all of these vaccines on subjects using high-tech machines to calculate their success rates, after which twenty vaccines reached the final testing stage.

Apart from that, around eighty-nine preclinical vaccines are already under investigation by researchers. Preclinical testing refers to testing vaccine first on cells and then on animals to see if it creates an immune response. It is safe to say that after completion of proper phases of trials and tests, the “one” vaccine with the highest success rate will be made public and would be deployed to clinics around the countries.

Phases of Coronavirus Vaccine

Currently, the coronavirus vaccine is being developed and tested in phases around the United States. In Phase 1, a small number of people were given the vaccine to test if the immune system responds effectively. Phase 1 also figures out how much dosage would be safe for patients to take.

In Phase 2, further safety of the vaccine is checked. Hundreds of people split into different groups, such as children, elders, and teenagers, made an appointment at other vaccination camps around the states to see if the vaccine would work all the same on them or differently. 

Phase 3 of the vaccine development is an efficacy trial involving vaccines given to thousands of people and see how many still catch the infection; this number is then compared to the volunteers who received a placebo. These trials are necessary to determine the efficacy rate and ensure that the vaccine is protective against the virus. This phase also reveals side effects, if there are any.

Authorities in the US are setting up vaccination camps around different states for Phase 2 and Phase 3; however, in other countries, such as China and Russia, the vaccine was given “early or limited approval” before detailed data verification of Phase 3, the evidence of vaccine’s safety being preliminary. However, authorities have issued a “serious risk” warning against such unverified deployments of the vaccine.

The “approval” would only come when the data from Phase 3 is positive; the approval would mean that the prioritized candidates would be able to get the vaccine first, while the whole public would get vaccinated after the new stock is developed.

If you want to appoint yourself as a prioritized vaccine candidate, get your appointment scheduled first for a coronavirus test and be sure if you can be the first to get immunity.
