- 3 years ago
A mixed vaccination of first AstraZeneca and then a Pfizer Covid-19 shot boosted neutralizing antibody levels by six times compared with two AstraZeneca doses, a study from South Korea showed.
The study involved 499 medical workers - 100 receiving mixed doses, 200 taking two doses of the Pfizer/BioNTech shot and the remainder getting two AstraZeneca shots.
The South Korean study also analysed neutralizing activity against major variants of concern, the Korea Disease Control and Prevention Agency (KDCA) said.
