Study In China Reveals Coronavirus Vaccine Found Effective During Human Trial

CORONAVIRUS VACCINE EFFECTIVE – The first phase of a COVID-19 vaccine study in China was found effective.

As the world reaches over 5 million reported coronavirus cases, a vaccine for the deadly disease becomes critical. Several vaccines are being studied with China leading the bulk of them.

According to an article from UPI, one of these potential vaccines were found to be safe and effective during human trials. Moreover, the first phase of the study was conducted with 108 patients over a span of 28 days.

However, these findings were still preliminary with the final results to be evaluated in six months. Most experts also predicted that a vaccine would be available after at least 18 months.

Due to the breakthrough, co-author of the study, Wei Chen, of the Beijing Institute of Biotechnology in China stated the results were an important milestone.

Still, he emphasized that the results needed to be interpreted cautiously. He explained that there could be unprecedented challenges when developing vaccines for the new coronavirus.

Currently, there are about 100 potential coronavirus vaccines being developed globally. However, as per the report, the adenovirus type 5 vectored COVID-19 or Ad5-nCoV was the first to undergo human trials.

The antivirus works by exposing a human’s cells with a weakened common cold virus, incapable of causing diseases. Afterward, the virus is used to deliver genetic material for the SARS-CoV-2 spike in cell proteins.

Once the spike protein has been produced, the immune system creates antibodies to fight against COVID-19.

The effectiveness of the virus was attributed to using three different doses in 108 healthy adults between 18 and 60 years old. Moreover, the participants had yet to be infected with the new coronavirus.

Our trial demonstrates that a single dose of the new adenovirus type 5 vectored COVID-19 vaccine produces virus-specific antibodies and T cells in 14 days, making it a potential candidate for further investigation
