I will say, and I know I will get flack for this, I am expecting and I got the vaccine. Studies as well as my doctor both said it was safe to get.
Now, from what I know the vaccine doesn't prevent me from getting Covid. But, usually with how vaccines work, if I do get it - it means I have a better chance of fighting it off because I have antibodies for it in my system. Getting the vaccine while pregnant (as long as it's not three weeks before delivery) has shown that the baby also will have antibodies for it.
