That has changed, my first two jabs were pfizer my booster 4 weeks ago was novavax.

I have chronic heart disease, so was concerned of the myocarditis/pericarditis risk had I risked another mRNA jab.

GP agreed and organised the novavax for me, did get the impression it was available to anyone= irrespective of whether or not they had cardiac issue.

Only side affect has been feeling of lethargy since, that could be old age and not the vaccine.
