It should not be given to children who are vomiting constantly or are dehydrated. 2  Do not use aspirin to treat your childâs fever or discomfort. Aspirin has been linked with side effects such as an upset stomach, intestinal bleeding and, most seriously, Reye syndrome. If your child is vomiting and cannot take anything by mouth, a rectal suppository may be needed.
Vaccines contain antigens and adjuvants. Vaccines generally have two major types of ingredients, antigens and adjuvants. Antigens are designed to cause the immune system to produce antibodies and/or T-cells against a specific pathogen or its toxin. Adjuvants amplify immune responses more generally.

Vaccines work by stimulating our immune system to produce antibodies (substances produced by the body to fight disease) without actually infecting us with the disease.They trigger the immune system to produce its own antibodies, as though the body has been infected with a disease. This is called active immunity.ow vaccines work.
