Study shows AZ+mRNA vaccination regimen is as good as two doses of mRNA

23 Sept 03:09 Key points summarised by AI
  • A German immunogenicity study, published in Nature Medicine, found that a mixed AstraZeneca (AZ) and mRNA vaccine regimen induces significantly high levels of anti-spike and neutralizing antibodies.
  • This AZ+mRNA combination produced antibody levels comparable to two doses of mRNA vaccines and ten times higher than an AZ-AZ regimen, while also generating a strong cellular immune response.
  • The study noted that the AZ-mRNA regimen, administered 9-12 weeks apart, resulted in fewer and acceptable side effects compared to the mRNA-mRNA regimen.
  • These findings suggest that the AZ+mRNA sequence could be an effective and well-tolerated formula for future vaccination strategies.
