The World Health Organisation doesn’t expect widespread vaccinations against COVID-19 until mid of the next year, said a spokeswoman of the world health body, stressin on the importance of rigorous checks on their effectiveness and safety.
“We are not expecting to see widespread vaccination until the middle of next year. This phase 3 must take longer because we need to see how truly protective the vaccine is and we also need to see how safe it is,” said spokeswoman Margaret Harris at a briefing in Geneva. Adding further, she said, “A lot of people have been vaccinated and what we don’t know is whether the vaccine works…at this stage we do not have the clear signal of whether or not it has the level of worthwhile efficacy and safety…”
Meanwhile, U.S. public health officials and Pfizer Inc, on September 3, said that a vaccine could be ready for distribution as soon as late October.
