London, May 22 (Prensa Latina) The University of Oxford has announced today that it wants to recruit 10,000 volunteers, including children and elderly to do more clinical tests on its coronavirus vaccine candidate.
The trials began last April with around 160 people between 18 and 55 years old, but now researchers at the Jenner Institute, which belongs to the prestigious British university, want to further expand the age range.
Professor Andrew Pollar, head of the Oxford Vaccine Group, explained that clinical studies are progressing and they will now begin assessing the vaccine’s ability to induce immune responses in the elderly and to test whether it protects a broader population range.
As he explained, the plan is to recruit people over the age of 70 and children between the ages of five and 12 to inoculate them with the vaccine candidate known as ChAdOx1 nCoV-19, because it is based on a chimpanzee adenovirus that was genetically modified to prevent reproduction in humans.
During the second and third phase of the clinical trial, the 10,260 volunteers who may not have had Covid-19, and in the case of women, not be or have been pregnant, will receive one or two doses of the vaccine candidate or from another being used as a comparison control.
After being inoculated, each test subject is to write down the symptoms they suffered during the following week and report if they think they were exposed to the infection, then a blood sample will be taken to determine if they are immune to the coronavirus.
The main goal of the study is to find out whether this vaccine works against Covid-19, if it does not cause unacceptable side effects and if it induces a good immune response, as per the Oxford researchers.
Most experts believe, however, that it will take between 12 to 18 months to produce an effective medicine on a large scale to the more than 100 laboratories participating worldwide in the race to find an antidote to Covid-19.
