Which Vaccines Contain Blood Products?
Vaccines are an important part of public health and preventing the spread of infectious diseases. While many vaccines are made from a weakened or inactivated form of a virus or bacteria, some vaccines are made from blood products.
Whole cell vaccines are vaccines made from a weakened form of the virus or bacteria. These vaccines are made by taking a sample of the virus or bacteria and weakening it, allowing it to be used to create the vaccine. Whole cell vaccines can contain various components, including blood products. For example, the yellow fever vaccine contains human blood products.
Subunit vaccines are made from pieces of the virus or bacteria, such as proteins, carbohydrates, or lipids. Subunit vaccines can also contain blood products, such as the hepatitis B vaccine. The hepatitis B vaccine contains a protein derived from human blood.
Conjugate vaccines are made from components of the virus or bacteria that are attached to a carrier molecule, such as a protein or sugar. Some conjugate vaccines, such as the Haemophilus influenzae type b (Hib) vaccine, contain blood products. The Hib vaccine contains a protein derived from human blood.
Toxoid vaccines are made from toxins produced by the virus or bacteria. These toxins are then inactivated, allowing them to be used as vaccines. Some toxoid vaccines, such as the diphtheria vaccine, contain blood products. The diphtheria vaccine contains a protein derived from human blood.
Live attenuated vaccines are made from a weakened form of the virus or bacteria. These vaccines can also contain blood products, such as the rotavirus vaccine. The rotavirus vaccine contains a protein derived from human blood.
In conclusion, some vaccines are made from blood products, such as whole cell vaccines, subunit vaccines, conjugate vaccines, toxoid vaccines, and live attenuated vaccines. Vaccines made from blood products should only be given to people with healthy immune systems, as they can cause serious side effects in those with weakened immune systems.
