Vaccines have a minuscule amount of the disease, so your immune system can easily destroy it and then retain in the immune systems memory the best way to destroy it. That is how vaccines work. However if you have an immune deficiency disorder, or a weak immune system, the disease inside the vaccine has a tiny chance of surviving and reproducing causing the disease to infect you.
Because the vaccine is a small piece of the antigen, a weakened or even dead version, the healthy immune system would overwhelm the antigen and immediately create antibodies for the disease. It is important to note that vaccines are only to be given when a person is healthy, because a weakened immune system could compromise the effectiveness of the vaccine.
According to the Center for Disease Control, you should always be up to date on routine vaccines such as the flu, measles, and so forth. Because conditions may be poor or even unknown to where you're visiting in Venezuela, you should also have Hepatitis A and Typhoid vaccines.
Because whenever there is a group of people together in a small space like classrooms, there is an increased chance of spreading infectious diseases. When more people are immunized against a disease, there is an increase in 'herd immunity'. That is, it's less likely that the disease will appear in that group, even if a few of them are not immunized for whatever reason. Keep in mind that there are people who cannot not get vaccines for medical reasons like allergy. So, if a family chose not to vaccinate their kids for non medical reasons, they not only increase their own risk of getting the disease, they also increase the risks of other children who cannot get the vaccine due to medical reasons.
No such thing at present. We don't even know what causes it.
Its not known actually but its beilived adolescents stress and tension leads to the disease
Opinion only: While most vaccines contain weakened or dead pathogens, the volume is so low that it alone cannot harm you. This low volume of pathogens, does, however, stimulate antibody production or cellular immunity within your body to act as a shield or protection against certain bacteria or viruses such as smallpox; measles; malaria; influenza, etc. Antibodies help to trap and kill germs that could lead to disease. Your body can make antibodies in two ways: by getting the disease or by getting the vaccine. Getting the vaccine is a much safer way to make antibodies without having to suffer the disease itself as well as being at risk of becoming disabled or even dying. Antibodies stay within your system for a long time and remember how to fight off a particular bacterium or virus. Some vaccines only require one dose (injection or capsule(s)) while others require periodic boosting. Some vaccines prevent one disease, while others can be combined to protect you from several diseases. As an example, the MMR vaccine protects you against Measles, Mumps and Rubella.
Also if they werent other diseases may not have even found a cure as many developed vaccines cure more things!!!! ... Thankyou for searching this :)
It's a vaccine for a bacteria, Haemophilus influenzae type B. Thanks to the effective of the vaccines, most doctor these days have no idea what it was like before when it caused childhood menigintis, epiglottitis, pneumonia, ect. This is actually true with quite a few diseases like polio, smallpox, even chicken pox. It's so rare to see these because the vaccines were so effective that the parents are more concern about the side effects of the vaccines than the disease themselves. No one remembers what it was like before the vaccines!
It is not known at this time what causes this disease but it can come on at any time in life, even baby's can suffer from it.
Most commonly, immunity: "a state of having sufficient biological defenses to avoid infection, disease, or other unwanted biological invasion." (Wikipedia). Immunity is naturally acquired (via exposure or maternally-transferred antibodies in utero) or artificially required through the use of vaccines.
Hello there! Vaccines are a preventative measure to make the person's immune system get familiar with the pathogen and learn how to completely neutralise them. Additionally, your immune system will develop a memory of how to beat them up effortlessly. Sometimes the person may not have symptoms during an actual infection, or they will just get a mild infection that is tolerable and doesn't require hospitalisation. Being vaccinated protects the immunocompromised and other people who did not get the vaccine. In that way, the pathogen gets a very slim chance to even replicate and mutate into some bad strain. That's how herd immunity can make terrible disease die out like the smallpox virus. These are the benefits of getting vaccinated and one should not be scared of getting one. If uncertain due to health issues or any other legit reason, it is best to consult a professional doctor for proper advice. Hope this response was helpful to you! 😃
Yes. The vaccines are not 100% effective.
Vaccines that are approved in the US by the Food and Drug Administration are considered much safer than the diseases that they prevent. If your physician or other health care professional recommends these for you, waste no time getting them to avoid hurtful effects from the disease. This is why medical professionals recommend vaccinations to their patients. The diseases, if not prevented, can cause much more illness and even death. When you get your vaccine, you will not only be less likely to become infected and ill yourself, but you will also be less likely to give the disease to others. When you get sick instead of preventing your illness, you can infect someone else who may not be able to withstand the disease and are not able to be vaccinated themselves to prevent it. This is true with infants who can not be vaccinated until their immune systems develop further after 6 months. Your protecting yourself also protects them. Any untoward effects from vaccine use is reported and monitored in the US by the VAERS (Vaccine Adverse Event Reporting System), see the related links below. The incidences of problems are very low, and, other than allergic reactions there are not many reasons not to take the vaccines. See the related questions below for more information.
