  • Lack of control: de-escalation in Spain: what can be done and when in each phase

The first Covid-19 vaccine to have reached the Phase 1 clinical trial is safe, well tolerated, and capable of eliciting an immune response against Sars-Cov-2 in humans, according to research published in The Lancet .

The study, carried out by the Beijing Institute of Biotechnology (China), was carried out on 108 healthy adults and after 28 days it shows promising results: the vaccine produces neutralizing antibodies and T-cell response against the virus.

In any case, more research is needed to confirm whether the vaccine and the immune response it elicits effectively protect against Sars-Cov-2 infection. The final results will be evaluated in six months. "These results represent an important milestone. The trial demonstrates that a single dose of the new Covid-19 vaccine using an adenovirus 5 vector (Ad5-nCoV) produces virus and T-cell specific antibodies within 14 days , makes it a potential candidate for further investigation, "says Professor Wei Chen, head of the study, adding that you have to be very cautious.

"The challenges in developing a Covid-19 vaccine are unprecedented and the ability to trigger these immune responses does not necessarily indicate that the vaccine protects people from Covid. These results give promising insight into developing vaccines, pro We are still a long way from making this vaccine available to everyone. "

Creating an effective vaccine is considered the long-term solution to control the pandemic. Currently, there are more than 100 candidate vaccines in development worldwide. One of the few that is in phase 1 is precisely this one, developed by the Beijing Institute of Biotechnology together with the Chinese laboratory CanSino Bio.

Another is that of the American laboratory Moderna Therapeutics, which announced positive results a few days ago by developing a certain immune response, although its results have not yet been published.
