Our regular commentator Cambridge University consultant clinical virologist Dr Chris Smith joins us with the latest Covid-19 science, and to answer your questions.
This week the Wellington region was put on alert level 2 restrictions after a traveller from Sydney spent the weekend in the city and then returned to Australia, where they tested positive for Covid-19.
Health officials are working under the assumption the visitor has the Delta variant, which is estimated to be 40 percent more transmissible than the Alpha variant. Dr Smith will discuss the Delta variant, and whether the current vaccines are robust enough to cope with the emerging Covid-19 variants.
