Covid vaccine distribution has begun in much of the developed world. Politicians, commentators and citizens criticize the slow start to immunizations. But like the Tour de France: What counts is not who wears the yellow jersey during the first stage, but who crosses the finish line first at the end. Three factors are crucial to that: vaccine supply, vaccine distribution and, most importantly, vaccination acceptance.
U.S. biotech company Moderna reported positive results from the first interim analysis of its Covid mRNA vaccine candidate. The IA found that of the 95 identified Covid cases in the study population 90 occurred in the placebo group, thus yielding a vaccine efficacy of 94,4%.
The pharmaceutical companies and universities racing to develop a corona vaccine are making strides: according to the World Health Organisation (WHO), 25 candidates are currently undergoing clinical trials.
