Longer gap between COVID-19 vaccine doses may increase immune response

Bangladesh, face a resurgence of COVID-19 cases, while at the same time, their supplies of vaccines remain severely limited.In these countries, poor vaccine supplies have led to longer gaps than recommended between the first and second doses, raising concerns about inadequate immune responses.The World Health Organization (WHO) recommends a gap of 8–12 weeks between the first and second doses of the AstraZeneca vaccine, one of the most widely distributed vaccines, globally.But a new study from the University of Oxford in the United Kingdom has provided reassurance that a second dose of the vaccine remains highly effective even after a gap of up to 45 weeks.In fact, the immune response of volunteers after an extended delay was superior to
