7-9 billion doses are necessary annually to keep re-infection rates low
For high levels of immunisation, around 10 billion Covid-19 vaccine doses are required globally by end of 2021 and further 7-9 billion doses are necessary annually to keep re-infection rates low and to slow down the pace of virus mutations, said a DHL white paper, Revisiting Pandemic Resilience .
DHL, which has distributed more than 200 million vaccine doses to over 120 countries to date involving over 350 facilities and 9,000 flights, said locally adapted last-mile delivery, distribution models and a constant stock of vaccines will continue to be critical beyond 2021.
