Successful Trial of Covid-19 Vaccine in Humans

China is a country that has successfully carried out research into the corona vaccine or Covid-19 developed in the country after the US pharmaceutical company, Moderna, now China has published the results of the study. The vaccine, made by the Beijing Institute of Biotechnologies and CanSino Biological, successfully triggers antidote antibodies in dozens of patients who are clinically tested at this early stage. The vaccine, named Ad5-nCoV, was approved for human trials in March. During the trial phase participants were aged 18 to 60 years. receiving low, moderate or high doses. There were 36 people in each of the three low, medium and high dose groups.

    For the results of clinical trials at this early stage was published in the medical journal The Lancet on Friday (5/22/2020). Candidates in previous vaccine trials were induced with antibodies that bind to most corona patients who have been infected for 28 days. In a vaccine trial on day 28, patients who received low and medium vaccine doses showed antidote antibodies compared to patients in the high dose group.

    According to experts, the concentration of antidote antibodies is very important to get patient protection from corona virus. The researchers also recommend that further research and trials be conducted with more volunteers before the vaccine is presented to the public. The vaccine, named Ad5-nCoV, was approved for human trials in March. During the trial phase participants were aged 18 to 60 years. receiving low, moderate or high doses. There were 36 people in each of the three low, medium and high dose groups.

    "This result is an important milestone," Wei Chen, professor at the Beijing Institute of Biotechnology and research leader told the media, was quoted as saying by CNBC International, Sunday (05/24/2020). "But it must be interpreted with caution. The challenges in developing the Covid-19 vaccine are unprecedented, and the ability to trigger an immune response does not always indicate that the vaccine will protect humans from Covid-19."

    In the notes of the World Health Organization (WHO) there are 8 corona vaccines that are being tested on humans. The four vaccines were developed in China. The rest, two United States (US), One in Germany and one in England.
