Dr. Connie Lehman, director of breast imaging, Massachusetts General Hospital, Boston:
People started getting vaccinated in December and we were having our healthcare workers in for their mammograms and we were like 'Wow this person has really enlarged lymph nodes'.

We had reported this in mammography centers before but nowhere near at the level we were seeing with the COVID vaccine. We think that’s because the COVID vaccine creates a very strong immunological response.

Let's hope that they really are 'false' positives. When you start pumping populations full of experimental drugs that mess with the body's immune response then that's playing around with a fundamental regulatory system in human health.

From the previous study - AZ's inefficacy wasn't down to it not generating a vigourous immune response in the body - it was doing that fine - just not one that was useful against Covid anymore.

Weirdly the study speculated that generating "an enhanced antibody response ..might confer better residual neutralizing activity against the B.1.351 variant".

Please don't do that!

I guess all this is why normal safety trials are meant to take several years, as Dan pointed out many moons ago.
