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.
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.
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.
Its not known actually but its beilived adolescents stress and tension leads to the disease
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!
Vaccines help prevent the spread of diseases through a phenomenon known as herd immunity. When a significant portion of the population is vaccinated, it reduces the overall prevalence of the disease, making it less likely for unvaccinated individuals to come into contact with the pathogen. This collective immunity protects those who cannot receive vaccines, such as individuals with certain medical conditions or allergies, by limiting the disease's ability to spread within the community. Ultimately, widespread vaccination contributes to lower infection rates and helps safeguard public health.
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.
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.
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.
