An inactivated vaccine uses a strain of a bacteria or virus that has been killed with heat or chemicals. The types of diseases that live-attenuated vaccines are used for include: As a live version of the virus or bacteria is included in this type of vaccine, medical advice should be sought before the vaccine is given as it may not be suitable for people with weakened immune systems or long-term health conditions. Recombinant and cell-based vaccines are produced using a different production process that does not require growth in eggs. Recombinant protein subunit vaccines are significantly more secure than live attenuated and inactivated/killed vaccines. Immunologic correlates of protection induced by vaccination.

It affects the liver by causing a wide range of diseases, from acute hepatitis (including fulminant hepatic failure), to chronic hepatitis, cirrhosis and potentially hepatocellular carcinoma (Liang, 2009). That's exactly what immunizations aim to do. vaccine: a substance given to stimulate the body's production of antibodies and provide immunity against a disease, prepared from the agent that causes the disease, or a synthetic substitute. The vaccines we get can help our bodies develop immunity, as tiny doses of the disease are introduced to our body, without causing illness. These usually happen very soon after getting the vaccine, and doctors' offices are well equipped to handle such reactions. They can also be used on almost everyone who needs them, including people with weakened immune systems and long-term health problems. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Few parents today have even heard of all of the diseases we vaccinate against, let alone seen a case of the measles, diphtheria, or whooping cough. It also avoids mutations that can occur when viruses are grown in eggs, which can sometimes affect how well the finished vaccine works. Thimerosal has been used as a preserving agent in some vaccines and other products since the 1930s. Another concern about vaccines involves the use of a mercury-based preservative called thimerosal.
