In the first stage of clinical trials, it is investigated whether the vaccine candidate is safe and possible side effects on a small number of volunteer healthy subjects.
In the second stage, the effectiveness of the vaccine candidate, whose reliability has been confirmed, is tested on more than 100 subjects.
In the third and final stage, the same process is repeated with several thousand subjects. This whole process can take months or even years.
According to the World Health Organization data, as of July 28, 25 vaccine candidates against Covid-19 are in the pre-clinical development stage and 139 vaccine candidates are in the clinical trial phase.
Covid-19, which emerged in China, spread to more than 200 countries and regions and turned into an epidemic. Worldwide, the number of cases exceeded 17 million 780 thousand, while more than 680 thousand people died.
