I remember the lines for polio sugar cubes as well as the smallpox vaccine in first grade....
I had an aunt pregnant and I believe she took the polio sugar cube at our local elementary
They opened for a month on weekends and you stopped by and took it
Orderly as I recall
As for vets and pregnant animals...indeed you are correct.
There is a distinction
Live vaccines are a no no
Killed ones are usually ok especially in latter half of gestation
Shorter gestation pets are more at risk
I wouldn’t vaccinate a pregnant pet just to be safe or I assume a pregnant woman unless it were dire...a real actual bring out the dead scenario...Ebola infections by the billions ...
I’m ambivalent
I was just with my late 80s aunt and uncle...they both had Covid last year
And the two stage vaccine three months ago
Neither had any side effects and he has pretty bad COPD
I have scar tissue on lungs from surgeries and pacemaker and pulmonary emboli and a leg clot...
I’m leery given what I read
I need the antibodies test...we think we all had it
