Reuters: Israel’s Health Ministry said on Sunday it is examining a small number of cases of heart inflammation in people who had received Pfizer’s COVID-19 vaccine.

Israel's pandemic response coordinator, Nachman Ash, said that a preliminary study showed "tens of incidents" of myocarditis (with) ... most cases reported among people up to age 30.

Nachman Ash: The Health Ministry is currently examining whether there is an excess in morbidity (disease rate) and whether it can be attributed to the vaccines.

Pfizer: (W)e have not observed a higher rate of myocarditis than what would be expected in the general population. A causal link to the vaccine has not been established.

There is no evidence at this time to conclude that myocarditis is a risk associated with the use of Pfizer/BNT COVID-19 vaccine.

The old 'no evidence' line again. Seems like there is some evidence though. Israel has been the most pro-active vaccinators in the world - why announce that a "preliminary study" had found cases? Just to stir up trouble against your own program?

Reading between the lines i'd say we've got another serious side effect coming to the fore.

The article doesn't say the time-lag - but mentions the cases were "primarily after the second dose".

This suggests a build-up sleeper effect, which is the worst kind of side-effect in terms of flagging it early - the kind you miss when you're in a rush with trials.

As with the blood clots, are your chances further increased with a yearly set of shots?
