First of all, there is no vaccine against chlamydia and/or gonorrhea. Chlamydia and/or gonorrhea are bacteria, so the treatment your spouse had to receive is an antibiotic (Ceftriaxone) that is given as a single injection into a muscle. This treats the infection, but it is still possible to get it again from another person
When a person is treated, it is recommended that they do not have sex for up to 7 days after taking the medication AND until the symptoms have gone away (whichever is longer). Otherwise, the person can transmit the infection to their partner. Moreover, a control test 2 weeks after the treatment is recommended to be sure that the infection has disappeared, given the resistance of certain bacteria to treatment. Especially if you are pregnant, if you catch the infection, there is a risk of transmitting the infection to your baby (severe eye and skin damage possible) during delivery and, more rarely, of having a premature delivery.
Usually, when a person is diagnosed with chlamydia and/or gonorrhea, all partners in the last 60 days should be screened to validate if they do not have an infection without having symptoms. So, in your situation:
- You should avoid having unprotected sex until your partner has a control test confirming that he or she is free of infection since you are pregnant. We don't want to take any chances.
- Considering the risk to your child, you should also get tested.
