Should I get the COVID Vaccine?
Yes! There are very few potential contraindications to COVID vaccine. Below are some special considerations:
What if I’m pregnant or breastfeeding? Pregnancy and breastfeeding are not contraindications for the COVID vaccine and should be discussed on a case-by-case basis with your family physician.
What if I’m on blood thinners? This question shows up on the COVID vaccine consent, however there is no problem receiving the COVID vaccine on blood thinners.
What if I have allergies? Allergies to medications or other vaccines is not a contraindication to receiving the COVID vaccine. If you had a reaction with your first dose or have a severe allergy to PEG or polysorbate, please speak to your family physician. PEG and polysorbate are used in skin care products, medications, and processed foods, so most people with this severe allergy are aware.
What if I am immunocompromised or have an autoimmune condition? You should still get the COVID vaccine, but it may be less effective as your medical condition may make you less likely to mount a strong immune response. You may want to speak to your family physician and/or specialist regarding the timing of your vaccine.
