Medical Procedures and Screenings After Getting the COVID-19 Shot

If you know you will need to have a medical procedure or go into the hospital or other medical facility, it is a good idea to get a COVID-19 vaccine first in order to protect yourself and others. Baystate Health no longer requires that you wait 4-6 weeks to get your COVID-19 vaccine.

Can the COVID-19 Vaccine or Booster Affect My Mammogram Results?

Yes. Research shows that lymph nodes can temporarily enlarge after receiving the COVID-19 vaccine. Swollen lymph nodes on the side of the injection are common and temporary, but they can cause a false reading on a mammogram. This swelling is a normal sign that your body is building protection against COVID-19.

Which Medical Procedures are Okay After Getting a COVID-19 Vaccine?

According to the CDC, most routine medical procedures or screenings can be performed before or after getting a COVID-19 vaccine.

These procedures include:

  • Routine blood work
  • Dental procedures
  • CT scans (also known as CAT scans or computed tomography), with or without IV contrast dye
  • EKGs (also known as ECGs or electrocardiograms)
  • Cardiac stress tests (also known as exercise tolerance tests or treadmill tests), with or without radiographic dye
  • Colonoscopies
  • Ultrasounds
  • Other medical screening exams
