in italy, gloria taliani, professor of infectious diseases at la sapienza university of rome. ondon, max lawson, head of inequality policy at oxfam international. a warm welcome to you all. if i could start with gloria, in italy, so, why is the eu excluding some vaccines, like covishield, which is a variant of astrazeneca, but made in india? >> well, the question is very interesting, because we really don't know exactly what the reason is. apparently, the declaration of the emaa society, the organization was, the factory, where the vaccine is produced, is not perfectly adequate for production of this kind of vaccine. or at least, it's not been certificated in a proper way. sami: if i could jump in, does that suggest the vaccines are not effective? >> well, this has not been proved. this has not been proved at all. the point is, the institute which produces the vaccine, the covishield, is the most relevant factory for vaccine production over the world. just remember that 60% of children are vaccinated with vaccines produced by this company. so it seems at least a little bit funn
