Seriously, a baby is better off in the uterus of someone who vapes pot than someone who gets a flu shot while pregnant. There might be bad sequelae both ways, but there is more chance the system can filter the cannabis out than the neurotoxic flu vaccine ingredients, including the heavy metals.
And when I was pregnant in Europe, my doctor told me to cut down on alcohol (I didn’t drink), down to one or two glasses of wine with dinner, and no more. That was in the 90s. Meaning everyone in Europe is born bathed in alcohol.
Please stop spreading your anti-vax misinformation. A pregnant woman who gets the flu vaccine not only protects herself, but her baby, since the antibodies her body produces in response to the vaccine cross the placenta and are contained in breast milk.
As for "heavy metals"--I am not sure what you are even talking about. If that is a reference to the sodium azide or thiomersal used in some vaccines, the dose of mercury is extremely small, much lower than any established harmful threshold. A pregnant woman consumes much more mercury in a tuna sandwich than she would ever receive in a flu shot. Furthermore, the preservatives are not used in single-dose vaccine formulations, so it isn't a given that the vaccine even contains them.
