Scientist behind the Oxford-AstraZeneca Covid-19 vaccine warns that the next pandemic could be even more deadly than the current one.
On the current threat from the emerging Omicron variant — which was has been detected in at least 16 U.S. states according to NBC News' tally — Gilbert said that its mutations were known to increase transmissibility, while immunities gained through vaccines or prior infection could be less effective against it.
"But as we have seen before, reduced protection against infection and mild disease does not necessarily mean reduced protection against severe disease and death," she said.The Delta variant remains by far the most dominant form of the virus in the U.S., accounting for 99.
Gilbert was delivering the annual Richard Dimbleby Lecture, named after a pioneering BBC broadcaster who died in 1965, where an expert in business, science or politics explains a topical issue. Previous speakers include World Wide Web inventor Tim Berners-Lee, European Central Bank chief Christine Lagarde and Bill Gates.
