And only one death. 1 in 6.8M is incredibly small risk.
My early hypothesis, based on the age of the 6 people and the fact that these are only women, is that it may be linked to birth control hormones, which elevate your risk of blood clots. If this was a widely distributed problem, you would see more instances, but perhaps if those people had other covariances for blood clots (e.g. they were also smokers), then the vaccine pushed them over the edge.
But still stopping all vaccinations for 1 death (and 6 cases) out of 6.8M boggles my mind. At the very least, you could continue for men (zero cases) and women over 48 years of age (zero cases).
