Mixing of Pfizer and AstraZeneca vaccine doses creates strong immune response: Study

According to a University of Oxford study, the mixing of Covid-19 vaccines from Pfizer and AstraZeneca generates a strong response. As per the research, a mixed shot of Pfizer dose followed by the Astra vaccine after a 4-week gap, and vice versa, resulted in high concentrations of antibodies. "This argues for flexibility in the use of these schedules, where local circumstances require it," Matthew Snape, an Oxford researcher said.
