Real-world data shows increased reactogenicity in adults after heterologous compared to homologous prime-boost COVID-19 vaccination.

RCT: Safety and immunogenicity of heterologous vs. homologous prime-boost schedules with an adenoviral vectored and mRNA COVID-19 vaccine.

Another study shows increased immune response with heterologous Oxford-AstraZeneca/mRNA vaccination.

Heterologous Oxford–AstraZeneca and Moderna Vaccination induce increased levels of neutralizing antibody compared to 2 doses of Oxford–AstraZeneca.

Heterologous Oxford–AstraZeneca and BioNTech/Pfizer Vaccination induce increased levels of neutralizing antibody compared to 2 doses of Oxford–AstraZeneca.

[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”.

Lab study shows heterologous AstraZeneca/Pfizer vaccination produces strong immune response against SARS-CoV-2 Delta variant.

Lab study shows a heterologous AstraZeneca + Pfizer immunization strategy provides stronger immunogenicity against Covid compared to homologous AZ + AZ or Pfizer + Pfizer strategies.

RCT: Mixing 2 different Covid vaccines is associated with increased risk of side effects.
