Hubby has had no side-effects at all which is a blessing.
Me, the 'problem child', had the chills and shakes before bed then woke in the night with Fitbit telling me my heart was beating at 111 beats per minute ! My blood pressure was not high at 133/75. Had a drink then took a soluble aspirin. I slept a few more hours.
This morning I rang the clinic and was told that is a 'normal' sort of reaction and they would have kept me in hospital to monitor me. I have had allergic reactions to other medications over the years.
All OK now, taking it quietly, keeping warm and keeping up the fluids.
I know of 2 healthy people in the US who were on ventilators for months and would prefer to avoid that ! Even though home now they are still not 100%.
Glad we've had the jab, at least we have some protection now.
