[Preprint] Mixing Covid jabs has good immune response, study finds – “The Com-Cov trial looked at the efficacy of either two doses of Pfizer, two of AstraZeneca, or one of them followed by the other. All combinations worked well, priming the immune system”.
Phase 2 RCT: Immunogenicity and reactogenicity of a Pfizer-BioNTech booster in patients that have received a single dose of AstraZeneca vaccine – “BNT162b2 (Pfizer) given as a second dose in individuals prime vaccinated with ChAdOx1-S (AstraZeneca) induced a robust immune response, with an acceptable and manageable reactogenicity profile”.
Commentary on Twitter
A study in @NatureMedicine shows that using a mRNA COVID-19 vaccine as a booster after a dose of the Oxford/AstraZeneca vaccine generated a better immune response. https://t.co/2jOprd0dO6 pic.twitter.com/9tK55KpgCM
