You needn't have just one rushed, insufficiently tested, potentially dangerous, morally reprehensible vaccine that probably doesn't work against a disease that almost certainly won't kill you. You can now have a cocktail of them!https://t.co/lXjSX01aRD

Same same but different?

Mixing and matching vaccine doses isn't totally unprecedented. But we're in seriously uncharted territory when it comes to Covid-19 vaccines, and experts are very wary of this update.https://t.co/Aeukx8utr0

NYTimes: MIXING?

The CDC noted that the authorized Covid-19 vaccines “are not interchangeable,” and that “the safety and efficacy of a mixed-product series have not been evaluated. Both doses of the series should be completed with the same product.”https://t.co/R61NPKksWM pic.twitter.com/piwfMMFM8G

This is playing with fire.

Remember you control your care:

✳️ Check what vaccine make you are being given.
✳️ Ensure your second dose is of the same vaccine.

There's no data proving the efficiency of doses from different vaccines. https://t.co/HYb4ypMyM5

I have to implement EBM for patients but I’m not to receive that same EBM? I signed up to 2 doses of a vaccine 3 weeks apart and not to clinical trial of another regime without either ethical approval or my consent.
