Timing of Vaccine Administration

As vaccines become more widely available, a practical question has arisen regarding the timing of vaccine administration with respect to certain invasive reproductive care treatments. In general, it is recommended that:

Patients scheduled for elective surgery or outpatient procedures, including oocyte retrieval, embryo transfer, and intrauterine insemination, avoid COVID-19 vaccination at least three days prior and three days after their procedure. This recommendation is not because being vaccinated is unsafe, but rather because known side effects of the vaccine may impact intra-operative and post-surgical monitoring. Common side effects after COVID-19 vaccination, especially after the second dose, include fever, chills, fatigue, myalgia, and headaches, which typically occur and resolve within three days. Anesthesia impairs normal thermoregulatory control and may be impacted by pre-existing fever. Additionally, these side effects would make it difficult to determine if a post-procedure fever is related to the vaccine or to a developing infection related to the procedure. Finally, many medical facilities may not allow patients into their facility or proceed with any elective procedure if a patient has COVID-like symptoms, including those that are possible side-effects of the vaccine, even if their COVID-19 test is negative. Practices should notify and encourage their patients to communicate with their surgeons and fertility programs when they become eligible for COVID vaccination. This will help coordinate planned surgical procedures, fertility testing and treatment, and will decrease the chance of inadvertent procedure cancellation.
