No international vaccine has yet been approved against “Covid 19”, which is caused by “the coronavirus that has killed more than a million people around the world.”
More than 40 pharmaceutical companies and research groups are conducting “human trials to develop vaccines, 7 of which have reached the advanced stages of testing.”The two companies aim to “start clinical trials on humans before the end of this year, in order to test safety and dose.”
In mice, the two companies said, “4 dose levels, were evaluated using a two-dose vaccination schedule, and added that preclinical results are under review prior to possible publication.”
“Two doses of MRT5500 neutralized antibody levels much higher than those observed in HIV-infected patients,” the two companies said.
“The preclinical results that we reported in this paper demonstrate the ability of MRT5500 to elicit a favorable immune response in non-human organisms,” said Translate Bio CEO Ronald Reno.
The candidate vaccine uses a technology known as (mRNA), which “directs cells in the body to manufacture specific coronavirus proteins that then produce an immune response.”
Many companies are also using this approach to develop a vaccine, “including the American companies” Moderna “and” Pfizer “, whose vaccines are in the late trial stage.
Sanofi is also developing another vaccine against the Corona virus in cooperation with the British pharmaceutical company, “Glasgow Smith Klein”, as “clinical trials began last September, while the first results are expected by the end of the year.”
