AstraZeneca vaccine shortcomings 18/6/21

There is very strong scientific evidence that AstraZeneca COVID vaccine a a significantly INFERIOR vaccine to the mRNA COVID vaccine. In my view, this is the real issue with AstraZeneca, not blood clots. Some of the evidence for this is at the bottom of this page.      Every Australian deserves access to the very best COVID protection not just the few.

There are a few solutions to this:

  • Solution 1. Dr Norman Swan's solution - the government should commit to all those getting AstraZeneca, to get them an mRNA vaccine booster by end of 2021. Elegant solution because of current short-supply of Pfizer in Australia. But has nto committed to do this. 

  • Solution 2. Vaccine Combinations. eg AstraZeneca first dose, Pfizer second dose. European countries plus Canada are already doing this.   Australian government

It is true that there seems to be growing evidence that AstraZeneca vaccine substantially reduces the likelihood of death and hospitalisation - at least with some COVID variants.   However, it seems that AstraZeneca is not nearly as effective against asymptomatic and mild/moderate COVID - and that is very problematic because up to 30% of asymptomatic to moderate infections can cause Long COVD - and that is VERY SERIOUS.

The Federal government needs to be open and honest with Australians, and commit to getting ALL Australians the best possible protection against COVID.  To date they are not doing that.

Dr Norman Swan says over-50s should get AstraZeneca now + Pfizer booster at years end. Better protection than 2 Pfizer shots.  25/May/21


  • At 2mins40 into this clip, Norman suggests that Aussie's 50+ will :

    • be better off getting AstraZeneca now plus Pfizer booster at years end  (He says that is what the Federal Government's policy SHOULD be promising to those Aussies 50+) THAN

    • waiting for 2 shots of Pfizer at the end of the year. If you wait till year's end, you will be in the queue behind 12 years old, and you probably won't get Pfizer shot till well into 2022.

    • If the Federal government made this commitment to Aussies 50+, this would then accelerate the take-up rate of AstraZeneca now, because it would offer a better option than what is currently on the table. And it would also be better for Australia, because it would help manage the major risk of a major COVID outbreak in Australia.

  • Norman acknowledges that the AstraZeneca is less effective versus Indian variant than Pfizer vaccine.

Some of the evidence that AstaZeneca vaccine is clearly an INFERIOR vaccine compared with mRNA vaccines from Pfizer and Moderna.

Slide from Anne de Gheest's Clinical presentation 30/Apr/2021. Note the line: "AstraZeneca is ineffective with B.1.351".  Based on the scientific research, Anne de Gheest concludes:


Opinion: The problem with AstraZeneca is not clotting, but effectiveness

A lot of questions surround the role of AstraZeneca in Australia’s Covid-19 vaccine program. Brisbane epidemiologist Steve Kisely says he wouldn’t take it, and it’s got nothing to do with blood clots.
