Malawi Sticks to AstraZeneca Despite Concerns Over Efficacy Lameck Masina BLANTYRE - Malawi's President Lazarus Chakwera says the country will go ahead with acquiring the AstraZeneca COVID-19 vaccine, despite concerns about its efficacy. Chakwera on Sunday evening announced Malawi has acquired 1.5 million doses and that additional ones were on the way to vaccinate a total of about four and a half million people. Chakwera said Malawi, one of Africa's poorest countries, settled for the AstraZeneca vaccine because it is cheaper. In a televised address on the fight against COVID-19, President Chakwera said the vaccine type coming to Malawi has an average of 60 to 70 percent efficacy. .
