Study leaders chose Brazil “because of the network of experienced and dedicated researchers who can support the conduct of quality clinical trials in the region,” Andrew Pollard, director of Oxford Vaccine Group and chief expert in SARS-CoV-2 vaccine studies, wrote in an email to Science. “Everything is done according to the strictest protocols,” says Soraya Smaili, the pharmacocolon and president of Unifesp. Along with other Oxford vaccine studies, this study was discontinued on September 6, supposedly because a British participant developed transverse myelitis; it was repeated on 12 September in Brazil and the United Kingdom, after independent safety observers concluded that the adverse event was probably not related to the study. 15. June: Imperial College London announces human vaccine trials A Chinese pharmaceutical company has said the coronavirus vaccine it is developing should be ready for global distribution by early 2021. COVID-19 vaccines require authorization from Anvisa, a reputable federal agency with highly qualified technical personnel. But Anvisa is not immune to political influence, as his boss is directly elected by the president. Pazuello and Antonio Barra Torres, director of Anvisa, are military officers appointed by Bolsonaro. However, so far, the Agency has remained in good conditions with scientists.
The vaccine is being tested in the United States on 45 participants between the ages of 18 and 55. The European Commission has invited Member States to start working to ensure that, once a vaccine has been authorised by the European Medicines Agency, they can store and transport it properly and have the skilled labour and medical equipment necessary to implement the procedure. Meanwhile, the BioNTech/Pfizer/Fosun Pharma consortium is recruiting 2,000 volunteers in São Paulo and Salvador for a phase III study of its messenger RNA vaccine, as part of a 29,000-person trial program, which also has sites in the United States, Argentina and Turkey. Johnson & Johnson`s Janssen vaccine was recently authorized to recruit 7,000 volunteers in Brazil for its vaccine, also based on an adenovirus. The company also plans to conduct studies in the United States and seven other countries with a total of 60,000 participants, according to data ClinicalTrials.gov. Here`s our updated timeline on the global coronavirus vaccine hunt: The vaccine is produced by Brazil`s Fundação Osvaldo Cruz, also known as Fiocruz, the country`s main public health organization, Franco said. British Foreign Secretary Dominic Raab accuses Russian authorities of stealing information related to research into a coronavirus vaccine. On July 19, Russia`s ambassador to Britain, Andrei Kelin, rejected the accusations and said they made “no sense.” The Oxford and AstraZeneca vaccine is considered one of the leading candidates already at an advanced stage of studies. It is also the first in the race for development to obtain authorization and become an official vaccine against the disease. The other vaccine candidate, who is one of the leaders of the race, is Sinovac, the Chinese candidate. Commission President Ursula von der Leyen has announced an EU deal with Johnson & Johnson that will guarantee 400 million doses of the vaccine.
This is the third contract the EU has concluded with a pharmaceutical company. .
