Don't expect global vaccine against coronavirus until mid-2021, says WHO
India TodayThe World Health Organization says it does not expect widespread immunisation against Covid-19 until mid-2021, despite growing expectations in the United States, the worst-hit nation, that a vaccine could be released within weeks. The UN health agency welcomed the fact that a "considerable number" of vaccine candidates had entered final stage trials, which typically involve tens of thousands of people. 'Trials too small' Russia has already approved a vaccine, and research published in The Lancet medical journal on Friday said patients involved in early tests developed antibodies with "no serious adverse events". Also on the list are movie stars Tom Hanks and more recently Robert Pattinson, whom Hollywood trade publications said contracted the disease while filming the latest Batman movie in Britain.
