Uy, sis, I'm really glad you asked this first instead of just showing up sa vaccination site! Given your tachycardia, thyroid issues, at especially that serious reaction you had sa tetanus vaccine during pregnancy, please talk to your doctor or cardiologist ASAP before any vaccine, ha. This is not something to decide on your own kasi may history ka ng complications, at they need to know the full picture.
A few of my mum friends with heart conditions din nagpa-consult muna with their doctors about timing at which vaccines are safe for them, it's totally normal to ask. Your health matters, lalo na kaya ka lang gumagawa for your family ngayon. Don't skip this step, okay?
