American Company Moderna held successful trials of the vaccine against coronavirus. The results of the trial showed that the medicine does not increase the risk of the exacerbation of the infection and can protect from the Covid-19, as bioRxiv reported.
The company said that during the studies, the scientists tested the vaccine on mice. The rodents got different amounts of vaccine, including doses, which are considered to be not strong enough to create protective immunity. After vaccine administration, the mice were infected with the coronavirus.
The trials showed that the medicine does not increase the risk of the severity of the disease and neutralizing activity of the vaccine might be reached by one dose.
Moreover, the vaccine protects the lungs from the Covid-19 infection without signs of the toxic effects and causes powerful immune response necessary for blocking of the infection.
It is noted that the company finished the second stage of the trials and it will proceed to the final one, which is planned for July. 30,000 people will participate in the next trial.
Earlier, US President Donald Trump said the country created a vaccine against coronavirus infection.
