While the vaccines available for use in pregnancy are still fairly newly developed, the ingredients in them are well known and their mechanisms of action are well understood - the information available doesn't point towards any significant risks of long-term negative effects for a developing baby. The vaccines available and recommended in pregnancy and childhood are all considered safe for the vast majority of people. There was some scare-mongering years ago about vaccines, but this has been discredited - the main research doctor was actually struck off for his misconduct in spreading false information.
There are some people who, for various reasons such as allergies or immunodeficiencies, can't have certain vaccines, but this is rare and there's no evidence to suggest that a prenatal exposure to maternal antibodies (the Covid vaccines available in pregnancy don't cross the placenta, only maternal antibodies are shared) would cause any problems with this.
There are risks with anything in life, any intervention and any lack of intervention. The way I see it is that the known, significant risks of Covid in pregnancy, plus any longer-term unknown risks from it, statistically far outweigh the risks of any clinically significant adverse effects from the vaccines based on the data we have available.
If you're not sure what to do, I'd suggest looking at the RCOG website (they have a lot of good quality evidence and guidelines) and speaking with your doctor or midwife - they'll be happy to help you.
