How to improve your childâs comfort with medicine. 1  Ibuprofen should only be used for children older than 6 months. 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.
There are 4 main types of vaccines: 1  live attenuated vaccines, which contain a living, but weakened, form of the germ (organism); 2  inactivated vaccines, which contain a killed form of the organism; 3  subunit vaccines, which contain just the part of the organism that stimulates an immune response (the antigen); and.n antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells â another type of immune system cell that helps protect against disease â is also important for some vaccines.
