US begins testing coronavirus vaccine

An experimental coronavirus vaccine began testing in the first American participants, US media reported.

The American pharmaceutical giant Pfizer and the German biotechnology company BioNTech announced that, as part of their global vaccine development program, the participants received separate doses at the Grossman School of Medicine at New York University in New York and at the Faculty of Medicine of the University of Maryland.

In Germany vaccines were applied to volunteers from that European nation last week and now also in the US. begins the development of human tests, under the program called BNT162, reports CNN.

“With our unique and robust clinical study program underway, starting in Europe and now in the US. In the US, we look forward to moving quickly and collaboratively with our partners at BioNTech and regulatory authorities to bring a safe and effective vaccine to the patients who need it most, ”said Albert Bourla, Pfizer President and CEO.

“The short period of less than four months in which we have been able to move from preclinical studies to human testing is extraordinary and further demonstrates our commitment to dedicate our best resources, from laboratory to manufacturing and beyond, to battle against COVID-19 ”, he explained.

“We are optimistic that moving towards multiple candidates in these human vaccine trials will allow us to identify the safest and most effective vaccination options (…),” said Ugur Sahin, CEO and co-founder of BioNTech.

The phase of the program, currently underway, is designed to assess the safety, efficacy and best dose level of four candidates for mRNA vaccines and will be evaluated in a single ongoing study, according to the companies.

Other projects have been developed at the same time in order to find a cure for the disease that has already caused the death of more than 250,000 people worldwide.

In April, for example, scientists at the Jenner Institute at the University of Oxford in the UK began testing their vaccine in humans, and based on the results of the trial, they say the result could be ready in September.

Eight vaccine programs are in the clinical trial phase and another 100 are in the preliminary stages, according to the World Health Organization (WHO).

At the end of April, they were 5 the most advanced in that sense, mostly in charge of China, country where the outbreak of the new coronavirus originated, whose first cases were reported in the last dates of 2019 from the city of Wuhan.
