The typhoid vaccine is used to prevent typhoid fever, a serious potentially life-threatening illness caused by Salmonella Typhi bacteria. The vaccine is widely considered to be both safe and effective at preventing this illness. However, a range of side effects may be experienced following the vaccine.
Two types of typhoid vaccine are available: a live, attenuated (weakened) oral vaccine and an inactivated (killed) vaccine in the form of an injection.
Side effects for the injection typically include swelling, redness or pain at the injection spot, headache, fever and general discomfort. These side effects can be alleviated through rest, over the counter pain medications, and hydration.
Side effects for the oral typhoid vaccine may include mild loosening of the bowel motions, nausea, and abdominal discomfort or cramping within 12-24 hours after each capsule is ingested. Very rarely people may have moderate diarrhoea or vomiting. Oral typhoid vaccine side effects can be minimised through hydration and rest. If these side effects become severe, contact a medical provider.
Side effects for both typhoid vaccines should not last for more than two days after receiving them. As with any vaccine or medication, there is a very small risk of developing a serious reaction. However, typhoid fever is far more dangerous to your health than the typhoid vaccine. If you have any questions about the typhoid vaccine, or its side effects, contact the medical provider who administered the vaccine to you.
