Scientists tackle vaccine safety, efficacy and access at global R&D forum
More than 2,800 scientists from 130 countries gathered on Friday (January 15) in a virtual forum hosted by the World Health Organization (WHO) to identify knowledge gaps and set research priorities for vaccines against SARS-CoV-2, the virus that causes COVID-19. They discussed the safety and efficacy of existing vaccines and new candidates, ways to optimize limited supply, and the need for additional safety studies. “The development and approval of several safe and effective vaccines less than a year after this virus was isolated and sequenced is an astounding scientific accomplishment,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General, in his opening remarks. “The approval of the first few vaccines does not mean the job is done. Far from it. More vaccines are in the pipeline, which must be evaluated to ensure we have enough doses to vaccinate everyone.” More than 30 million vaccine doses have already been administered in 47 mostly high-income countries.
