A conjugate vaccine is created by covalently attaching a poor antigen to a strong antigen thereby eliciting a stronger immunological response to the poor antigen. Most commonly, the poor antigen is a polysaccharide that is attached to strong protein antigen.
Diphtheria, Tetanus, and Pertussis (DTaP) Vaccines What You Need to Know . Why get vaccinated? Diphtheria, tetanus, and pertussis are serious diseases caused by bacteria. Diphtheria and pertussis are spread from person to person. Tetanus enters the body through cuts or wounds. DIPHTHERIA causes a thick covering in the back of the throat.
When it comes to the flu vaccine, the question for almost everyone shouldn't be if you should get it, but how you should get it. There are two options: the flu shot and the nasal spray FluMist. Most years, both offer about the same level of protection, but some people are better suited for the shot, while others do better with the spray.
There are 4 main types of vaccines: Live-attenuated vaccines; Inactivated vaccines; Subunit, recombinant, polysaccharide, and conjugate vaccines; Toxoid vaccines; Live-attenuated vaccines. Live vaccines use a weakened (or attenuated) form of the germ that causes a disease.
Measles, mumps, and rubella vaccine viruses are not transmitted from the vaccinated person, so a recently vaccinated person would not pose a risk to a pregnant woman. This information was taken directly from the MMR (Measles, Mumps & Rubella) Vaccine information Statement (VIS) dated 04/20/2012.
In 1955, before the introduction of polio immunisation, there were nearly 4,000 reported cases of polio in England and Wales. Polio is now very rare in the UK because of the success of immunisation. Since 1988, the World Health Organization (WHO) has organised an immunisation programme to remove polio virus from every country in the world.
Like inactivated vaccines, subunit vaccines do not contain live components and are considered as very safe. Key point Rather than introducing a whole-cell vaccine (either inactivated or attenuated) to an immune system, a subunit vaccine contains a fragment of the pathogen and elicits an appropriate immune response.
Chickenpox is a very contagious disease caused by the varicella-zoster virus (VZV). It causes a blister-like rash, itching, tiredness, and fever. Chickenpox used to be very common in the United States. Each year, chickenpox caused about 4 million cases, about 10,600 hospitalizations and 100 to 150 deaths.
