How Vaccines Work There are two main groups of vaccines: live-attenuated vaccines and inactivated vaccines. Live-attenuated vaccines: Live-attenuated basically means alive, but very weak. These vaccines are made when the virus is weakened to such a level that they reproduce only about 20 times in the body.

HIV/AIDS Vaccine: An Update Broadly speaking, the potential HIV vaccines may be classified as:(9). Live attenuated vaccines: Although scientists have studied live attenuated vaccines against HIV in animals, where they have shown high levels of protection, they are not currently being developed for use in humans because of safety concerns.

- Live attenuated vaccines. Live vaccines are derived from “wild,” or disease-causing, virus or bacteria. These wild viruses or bacteria are attenuated, or weakened, in a laboratory, usually by repeated culturing. For example, the measles vaccine used today was isolated from a child with measles disease in 1954.ive attenuated vaccines.

Vaccines for Children - A Guide for Parents and Caregivers Vaccines are frequently given by injection (a shot), but some are given by mouth and one is sprayed into the nose. There are various types of vaccines that are routinely given to children Attenuated (weakened) live viruses- These vaccines contain a live virus that has been weakened during the manufacturing process so that they do not cause the actual disease in the person being vaccinated.

It’s for healthy people ages 2 to 49 who aren’t pregnant, who are not allergic to the flu vaccine or any of its ingredients, and who don’t have weak immune systems. It should not be used for the 2016-2017 flu season.

Anthrax Human anthrax vaccines were developed by the Soviet Union in the late 1930s and in the US and UK in the 1950s. The current vaccine approved by the U.S. Food and Drug Administration (FDA) was formulated in the 1960s. Currently administered human anthrax vaccines include acellular (USA, UK) and live spore (Russia) varieties. All currently used anthrax vaccines show considerable local and general reactogenicity (erythema, induration, soreness, fever) and serious adverse reactions occur in about 1% of recipients.

Different Types of Vaccines The smallpox vaccine used cowpox, a poxvirus that was similar enough to smallpox to protect against it but usually didn’t cause serious illness. Rabies was the first virus attenuated in a lab to create a vaccine for humans.Vaccines are made using several different processes.onjugate vaccines are somewhat similar to recombinant vaccines: they’re made using a combination of two different components. Conjugate vaccines, however, are made using pieces from the coats of bacteria. These coats are chemically linked to a carrier protein, and the combination is used as a vaccine.

Live Vaccines and Vaccine Shedding Live vs. Inactivated Vaccines. Live vaccines contain a weakened or attenuated form of a virus or bacteria. They are altered so that they can't cause disease. The other main type of vaccine is made of the inactivated virus or bacteria (whole vaccine) or just parts of the virus or bacteria (fractional vaccine).

- There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacteria in a laboratory.lthough live attenuated vaccines replicate, they usually do not cause disease, such as may occur with the natural (“wild”) organism. When a live attenuated vaccine does cause “disease,” it is usually much milder than the natural disease, and is referred to as an adverse reaction.
