June 14, at 3: The first outbreaks in Australia, in12 years after the introduction of Dtap, all the victims were fully vaccinated, all aged I tested most of them………Albany, Western Australia, city of 45, people, all coughed over for about 8 months. NO ONE over age 12 caught whooping cough, no grannies, no mums and dads, just all the Dtap kids, whose vaccine obviously fails around 3 years after last jab.
Can vaccines cause or spread diseases? No, with some extremely rare exceptions The longer answer: There is a theoretical risk that live attentuated vaccines like the MMR can be found in body fluids known as sheddingbut that does NOT mean they are capable of causing the disease in the person vaccinated, much less being passed on, or causing disease in anyone else.
Even the most severely immunocompromised individuals can be around recently vaccinated people with all vaccines, the ONLY exceptions being the live polio vaccine not used in Australiaand a few very simple precautions are needed for the chicken pox or rotavirus vaccine, or the influenza nasal spray also not available in Australia.
The even longer answer! Definitions A germ is an infectious microorganism, such as a bacterium or virus, capable of causing disease. For a germ to cause disease, for someone to actually get sick from a bacterial or viral infection, the germ needs to be potent enough to overcome the defenses of that person, and then it needs to be capable of causing harm.
Virulence is the term used to describe how potent and dangerous a germ is, how likely it is to be able to overcome a healthy persons natural defenses, and then how likely it is to cause damage or sickness.
Some germs are extremely virulent, and capable of breaking through even the strongest unimmunised defenses vaccines boost specific immunity for some really virulent diseases, so your own body can be helped to be strong enough to defend against them.
Pertussis (whooping cough) – contains fragments of the bacteria and a small harmless section of the toxin. This vaccine CANNOT cause the disease, so cannot . Pertussis is most likely to spread to others early in the illness. Persons with pertussis can no longer spread the disease once they have completed 5 days of treatment with antibiotics. However, persons with pertussis who do not take antibiotics can spread the disease during the first 21 days of illness. Pertussis, or whooping cough, is an upper respiratory infection. It is caused by the Bordetella pertussis bacteria. It is a serious disease that can affect people of any age and cause permanent disability in infants, and even death.
Other germs are opportunistic, and can only cause disease if the host defenses are somehow damaged or deficient, for example if they are immunosuppressed with disease or medication, or frail with old age. Vaccines increase the resistance of a person to infection.
Transmission is when an infectious person passes a germ on to someone else. There are a number of ways in which a germ can be transmitted, for example, when a person gets sick with an infection they may cough or sneeze, and spray tiny particles laden with germs into the air via droplets.
Or, germs in faeces, and vomit can be spread via contaminated surfaces such as bathroom taps and door handles. Other infections can be transmitted in blood between people through activities such as sharing needles or having sex.
An infectious disease that can be transmitted between individuals is said to be contagious. Shedding occurs when a germ that is infecting someone is then present in one or other of their body fluids, and could be transmitted to another person.
Types of vaccines — subunit, split and toxoid To understand any risks associated with vaccines, is important to understand that there are different kinds of vaccines. Vaccines can be described as being made up of subunit or split particles, toxoid, or being live and attenuated.
Subunit or split particle vaccines contain fragments of germs, not the whole thing. Some diseases are not caused by the germ itself, but by a toxin that the germ produces. Toxoid vaccines are made to prevent that kind of disease, and so contain an inactivated toxin known as a toxoidbut not the germ itself.
The toxins are inactivated and so are not capable of causing harm Tetanusand diphtheria are toxin mediated diseases, and the vaccines that protect you from them are toxoid vaccines.
These vaccines are enough to show your immune system what they need to be able to fight off, but it is utterly physically impossible for them to cause disease in the person receiving the vaccine.
This of course also means that they cannot be shed, let alone be transmitted to cause disease in anyone else. Vaccines in this category include those for: Pertussis whooping cough — contains fragments of the bacteria and a small harmless section of the toxin.
The pertussis vaccine does not protect against these diseases. Is there a lab test for parapertussis/holmesii? Yes. To test for parapertussis or holmesii, the nasal passages are swabbed. Nasal material on the swab is then examined in the lab for the presence of parapertussis or holmesii bacteria. Parapertussis and holmesii are spread. Diphtheria, tetanus and pertussis are very serious bacterial diseases. While diphtheria and pertussis spread from person to person, tetanus enters the body through broken skin. Before the DTaP vaccine became available to the public, roughly , people contracted diphtheria and tetanus, and. The pertussis vaccine simply cannot cause whooping cough, as it doesn’t have any live bacteria or toxin in it. It’s physically impossible. It’s physically impossible. You can only get sick if you’re exposed to someone who’s infected, and if you and they are vaccinated, the risk is greatly reduced.
Diphtheria — a toxoid vaccine contains some of the diphtheria toxin which has been inactivated. This vaccine contains no bacteriaso cannot be shed or transmitted. Tetanus — a toxoid vaccine contains some of the tetanus toxin that has been inactivated.
Hepatitis B — contains only fragments of the virus, so cannot be shed or transmitted. HiB — contains only the outer shell of the bacteria, so cannot be shed or transmitted.
IPV inactivated polio vaccine — In Australia, only the inactivated killed polio vaccine is used, so it cannot be shed or transmitted.
Pneumococcus — contains fragments of the bacteria, so cannot be shed or transmitted. These DO contain whole germs.
However, these germs have been attenuated, or weakened, meaning that their virulence has been removed. They are, however, similar enough to the germs found out in the wild so your immune system gets a specific boost as it gets shown what the real germs might look like, so is ready to fight off the dangerous infection should it come along.
The following are live attenuated vaccines:pertussis (whooping cough) vaccination and adults who have not Pertussis is spread from person to person. The infection gets into your body through your nose, mouth or eyes.
When an infected person coughs or sneezes, bacteria-containing droplets get in the air.
If . Whooping cough (pertussis) spreads easily by coughing and sneezing. Vaccination is necessary to stop or slow its spread of the disease. The whooping cough vaccine is the best protection for yourself, your family, and especially small babies, who can develop serious complications from this disease.
The pertussis vaccine does not protect against these diseases. Is there a lab test for parapertussis/holmesii?
Yes. To test for parapertussis or holmesii, the nasal passages are swabbed. Nasal material on the swab is then examined in the lab for the presence of parapertussis or holmesii bacteria. Parapertussis and holmesii are spread. Whooping cough (also known as pertussis or day cough) is a highly contagious bacterial disease.
  Initially, symptoms are usually similar to those of the common cold with a runny nose, . And because of waning immunity, vaccines don’t do as good a job of preventing the spread of pertussis and mumps as we would like. Still, that’s only when the vaccines don’t work, and even then, as Dr.
Bob says, they do work to reduce the severity of symptoms. Whooping cough is spread through the air by coughing and sneezing. It is very contagious.
should be vaccinated against whooping cough. The vaccine for infants and children is combined with diphtheria and tetanus vaccine as DTaP. The schedule is 4 doses at 2, 4, 6 and months of age.
