There are 2 types of vaccines:
(1) Live ("attenuated", or bred to be harmless)
(2) Killed (dead disease-causing particles)
Live vaccines can be more effective, don't usually need 'booster' shots later to make them work better, but are less able to be given to immunocompromised or pregnant people as they are still alive.
Killed vaccines are less effective, often requiring boosters, but can be given to immunocompromised people and (often) pregnant ladies. They are used with an "adjuvant", or a substance that helps them work better (makes your body more able to make antibodies to them faster).
Both types of vaccines have 'epitopes', or molecules that your body recognises. These epitopes are the SAME as what is on the actual disease-causing particles. This is why they work - your body sees the "HARMLESS" particles and learns to recognise them, or creates "antibodies" that help your body respond to the actual thing when it appears.
It takes time to create these antibodies, so if you can make them BEFORE the actual disease finds its way into your body, you can respond much faster and destroy the virus particles before they can cause you harm.
The type of vaccine depends on what has been developed. There are benefits of both ways, but it is not always easy to do both.
Side note: occasionally, you will hear about how "vaccines are horrible, and cause more harm than good". Most of the time, people use multi-resistant organisms as examples, however, these organisms become resistant to ANTIBIOTICS, and NOT vaccines! Having antibodies is natural, unlike many antibiotics! They are NOT comparable! Antibodies are a post-infection method of disease control, whereas vaccines prevent the disease from establishing. Thus, vaccines have in the past been used rather successfully to rid the world of several diseases! (Which we can ALL be extremely grateful for!!!!!)
Another poorly-used example was that of the smallpox vaccine causing many deaths. Reasons why this example is tragically misused is that it was the first-ever attempt at vaccination in recorded history (we no longer live in such an age where we must rely on random human-testing of live NON-attenuated pathogen injection!). Smallpox protection included injecting pus from the lesions of an infected person (or another vaccinated person) to create antibodies.
Case in point: we no longer inject pus into people... it's a good way to spread other infections, and is less reliable in results. We no longer live in the 'dark ages' of immunology. The first attempts at reaching space failed badly, and yet nobody seems to be boycotting space travel now that science and technology has improved, so please be open-minded if anyone ever tells you that in vaccines, in general, are "bad". Okay? :)
Yes, vaccines can be used to prevent certain bacterial infections by stimulating the immune system to produce antibodies against specific bacteria. Examples include the vaccines for tetanus, pertussis, and pneumococcal infections. Vaccines have been successful in reducing the incidence of these bacterial diseases.
There are vaccines available for certain types of bacterial meningitis, particularly caused by Neisseria meningitidis and Streptococcus pneumoniae bacteria. Vaccines like MenACWY and PCV13 help protect against these bacteria by stimulating the immune system to produce antibodies against them. Vaccination is an effective way to prevent bacterial meningitis and its complications.
There are several vaccines to prevent bacterial infections, but not nearly as many as there are for viral infections. One widely used today is the vaccine for bacterial pneumonia which has been very effective in reducing death from this infection in the elderly. Other frequently used vaccines for bacterial diseases include those for: meningitis, cholera, salmonella, anthrax, plague, Hib, and tuberculosis.
No, bacterial cells do not contain nuclei. Bacterial cells are prokaryotic, which means they do not have a membrane-bound nucleus. Instead, their genetic material is present in a circular chromosome located in the nucleoid region of the cell.
preventing infectious diseases by stimulating the immune system to produce an immune response without causing the disease itself. This helps protect individuals and communities by building immunity and reducing the spread of diseases.
There are several vaccines that protect against bacterial meningitis, targeting different bacteria. The most common ones include the meningococcal vaccines (like MenACWY and MenB), the pneumococcal vaccines (PCV13 and PPSV23), and the Hib vaccine for Haemophilus influenzae type b. These vaccines help prevent infections caused by the specific bacteria associated with bacterial meningitis.
No. Vaccines are not used for treatment. They are used as prevention.
Penicillin is for bacterial disease.

yes they do
Most pneumonia vaccines, including the pneumococcal vaccines, do not contain mercury. Some vaccines historically contained thimerosal, a mercury-containing preservative, but many vaccines have been reformulated to eliminate this ingredient. Current formulations of pneumonia vaccines are considered safe and do not pose mercury-related risks. Always consult with a healthcare provider for specific vaccine ingredient information.
Vaccines are used to make your body produce antibodiesand T-cells against viruses or bacteria! The Measles and Flu vaccines are viral. The Whooping Cough (Pertussis) and Tuberculosis vaccines are bacterial.
Vaccines do not destroy pathogens, they give the immune system antibodies so it can destroy a pathogen before it causes an infection. Vaccines do exist for some bacterial infections.
Among others, seasonal flu vaccines into multi-dose containers may contain mercury, labeled as thimerisol. Mercury has been removed from most other vaccines. If you have concerns, you should check with your health care provider.....and avoid eating tuna and most other fish.
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
Yes, Tetanus Toxoid does contain Thimerosal (mercury), in most vaccines. BUT, there are several tetanus vaccines that are free of mercury. Infanrix, Daptacel, ADACEL and Boostrix have no mercury in them. Tripedia is manufactured with thimerosal that is gradually diluted out of the final product. Some older ones still contain up to 25mcg/0.5ml of mercury.
