If swelling and redness at the injection site after my COVID-19 vaccine last longer than a couple days does this indicate a serious problem? How long is too long?

Question: 

If swelling and redness at the injection site after my COVID-19 vaccine last longer than a couple days does this indicate a serious problem? How long is too long?

Answer: 
Pain, redness, itchiness or swelling at the injection site are common reactions to the COVID-19 vaccines. These reactions can happen right away and/or 7 days after and last one to two days but can sometimes last longer.
 
If you have concerns regarding a vaccine reaction, it is recommended that you contact the health care provider that gave you the vaccine. Pain and swelling can be managed with cold compresses at the injection site and acetaminophen, if needed. Avoid pressure on the injection site.
 
Pain or redness, or swelling that extends past the nearest joint (shoulder or elbow) or that lasts for 10 days or more should be reported to the health care provider that gave the vaccine if possible. It is important to always report unexpected or serious reactions to a health care provider so that they can be investigated further. If you don't know who gave your vaccine, call your local health unit to report. You can find the number here.
 
If you are concerned about your health, please speak with your health care provider. You can also contact HealthLink BC at 8-1-1.
