El laboratorio Moderna Inc ha realizado una prueba preliminar en personas sanas que habría funcionado al generar un nivel de anticuerpos igual o superior al de pacientes recuperados de la enfermedad.

La farmacéutica estadounidense Moderna Inc, una de las que trabaja en la búsqueda de la vacuna para el coronavirus, ha anunciado que su vacuna experimental ha dado resultados prometedores en el primer ensayo con humanos.

Los hallazgos, que han verificado que la vacuna mRNA-1273 es segura y capaz de estimular una respuesta inmune contra el COVID-19, se basan en los resultados obtenidos tras probarla en ocho personas, según informa la propia empresa en un comunicado.

Este primer grupo de voluntarios sanos ha recibido dos dosis de la vacuna desde el mes de marzo. Sus organismos fabricaron anticuerpos que después fueron probados en células humanas en un laboratorio y consiguieron evitar que el virus se replicase.

Según ha explicado la farmacéutica, en todas las personas tratadas el nivel de anticuerpos era igual o superior al de pacientes que habían pasado la enfermedad.

El presidente de Estados Unidos, Donald Trump, ya ha mostrado satisfacción por los avances realizados en su país. “Hay grandes noticias sobre curas, tratamientos y vacunas. He visto resultados y son asombrosamente buenos”, ha explicado en rueda de prensa. Queda por comprobar si una vez alcanzados los resultados finales, Trump se mostrará igual de satisfecho por compartirlos con el resto de países.

Una posible vacuna a finales de este año
El laboratorio sigue trabajando a la carrera para encontrar la cura a la pandemia mundial. En una segunda fase, que cuenta con el visto bueno de la agencia de gobierno responsable de la regulación de los medicamentos (Food and Drug Administration) para desarrollarse este mes, la vacuna experimental será administrada a 600 personas.

Se espera que en julio se pueda proceder a una tercera fase con miles de voluntarios.

Tal y como ha indicado el doctor Tal Zaks, director médico de Moderna, si este procedimiento marcha bien, la vacuna podría estar lista para su uso generalizado a principios del 2021.

La tecnología del estudio
En las investigaciones que desarrollan laboratorios y farmacéuticas de todo el mundo para encontrar la cura del coronavirus, Moderna Inc, junto con un equipo chino, habían sido los dos primeros en anunciar avances en el mes de marzo. En la actualidad hay 11 vacunas experimentales en todo el mundo.

La tecnología que concretamente utiliza Moderna es la del ARN mensajero, que implica que la vacuna la produce el propio organismo tras su administración.


A US pharmaceutical company ensures positive results in its coronavirus vaccine


The Moderna Inc laboratory has carried out a preliminary test in healthy people that would have worked by generating an antibody level equal to or greater than that of patients recovered from the disease.

The American pharmacist Moderna Inc, one of those working on the search for the coronavirus vaccine, has announced that its experimental vaccine has shown promising results in the first human trial.

The findings, which have verified that the mRNA-1273 vaccine is safe and capable of stimulating an immune response against COVID-19, are based on the results obtained after testing it on eight people, according to the company itself in a statement.

This first group of healthy volunteers has received two doses of the vaccine since March. Their organisms made antibodies that were later tested in human cells in a laboratory and managed to prevent the virus from replicating.

As explained by the pharmacist, in all treated people the level of antibodies was equal to or higher than in patients who had passed the disease.

The President of the United States, Donald Trump, has already shown satisfaction with the progress made in his country. “There is great news about cures, treatments and vaccines. I have seen results and they are amazingly good,” he explained at a press conference. It remains to be seen if, once the final results are reached, Trump will be just as satisfied to share them with the rest of the countries.

A possible vaccine later this year
The lab continues to race to find the cure to the global pandemic. In a second phase, which has the go-ahead from the government agency responsible for drug regulation (Food and Drug Administration) to be developed this month, the experimental vaccine will be administered to 600 people.

A third phase is expected in July with thousands of volunteers.

As Dr. Tal Zaks, medical director of Moderna, has indicated, if this procedure works well, the vaccine could be ready for widespread use in early 2021.

The study technology
In research carried out by laboratories and pharmaceutical companies around the world to find the coronavirus cure, Moderna Inc, together with a Chinese team, had been the first two to announce advances in March. There are currently 11 experimental vaccines worldwide.

The technology that Moderna specifically uses is that of messenger RNA, which implies that the vaccine is produced by the body itself after administration.
