Will the vaccine trigger a sickle cell crisis and if I have a lot of crises should I still get the vaccine?

Side effects from the vaccine are possible. The most common side effects are an ache for 1-2 days at the site of injection, headache, fever, and body aches. These side effects go away after a few days. It is unlikely that the vaccine will trigger a sickle cell crisis, but if anyone has severe symptoms they should seek medical attention.
