BERLIN (AP) — The head of the World Health Organization says he’s worried about the omicron and delta variants of COVID-19 producing a “tsunami” of cases between them. Top officials with the U.N. health agency cautioned Wednesday that it’s still too early to be reassured by initial data suggesting that the omicron variant leads to milder disease. WHO’s director-general urged everyone to make a “new year’s resolution” to get behind a campaign to vaccinate 70% of countries’ populations by the beginning of July. Ninety-two of WHO’s 194 member countries missed a target to vaccinate 40% of their populations by the end of this year
