Ninitial clinical trials of the vaccine have been shown to elicit an immune response in volunteers, according to a study being carried out by scientists at the University of Bristol in the United Kingdom, reports the newspaper The Sun.
Normally, vaccines use a weakened form of the virus, or small amounts of it, in their formulation, however the innovative Oxford vaccine makes the body part of the virus itself.
The researchers found that this new technique works for the new coronavirus.
The study used cells in the laboratory and detected that the vaccine instructs the protein in the Covid, which cells then replicate thousands of times – producing it in huge quantities.
Due to this process, the system immune of people is prepared to recognize the disease and combatit without individuals getting sick.
Professor David Matthews, from the Faculty of Cellular and Molecular Medicine (CMM), from the University of Bristol, who led the study, said: “so far, technology has not been able to give very clear answers, but we know that this vaccine is doing everything we expected, and that it works perfectly. This is the only one good news in our fight against Covid-19″.
Sarah Gilbert, in charge of the clinical trials at the University of Oxford, said: “This study confirms that large amounts of the new spike protein coronavirus are produced quite accurately, and this is highly promising to explain the vaccine’s success in inducing a strong immune response “.
The death of the volunteer
The doctor and volunteer João Pedro Feitosa died of complications while taking part in clinical trials. It is believed that the doctor will not have received the vaccine, but a benign placebo.
However, testing for the vaccine is already underway again.
To date, the AZD1222 vaccine has been administered to 18,000 people in clinical trials, which are taking place in the United Kingdom, Africa South, United States and Brazil.
The Oxford vaccine and the AstraZeneca remains the great hope to be able to halt the spread of Covid-19 worldwide.
