Let’s say you got a shot of the Johnson & Johnson vaccine or even the AstraZeneca vaccine. Can you get one of the statistically more effective mRNA vaccines such as the Moderna or Pfizer? The answer comes from $ Denmark where researchers reviewed the experience of some 5.5 million Danes.
The records show that 144,360 received the AstraZeneca vaccine as a first dose but then 136,551 of them received an mRNA vaccine as the second dose. The vaccine effectiveness of this combo was 88%. This figure is very close to the 95% vaccine efficiency figure published for 2 dose courses of the Moderna and Pfizer vaccines and significantly higher than 66-70% figure for the full 2 dose AstraZeneca vaccination course.
What about Delta? Data from Germany shows that the mixed vaccination regimen yields effectiveness against the Delta variant equal to a full 2 shot course of Pfizer vaccine. There were no significant side effects.
