Vaccinations and Drugs

Vaccinactions involve injecting a small amount of dead or inactive pathogens into the body, these pathogens still carry antigens which means our white blood cells will still try to find the right antibodies to attack them even though they are harmless. But this means that if the same type of pathogen entres the body again then white blood cells can rapidly mass produce the correct antibodies to kill the pathogens. Therefore you dont get ill.

Pros:

1) Vaccinations have helped to control lots of the comminicable diseases that were once comman, such as rubella, mumps,tetanus.

2) Disease epidemics can be prevented if a large number of the population has been vaccinated. That way the unvaccinated people are less likely to catch the disease. ( if you have 100 people and 96 of them are vaccinated for tetnus, 2 of them are not vaccinated and the other 2 have tetnus, its very unlikely that the 2 unvaccinated people will come in contact with the 2 people that have tentus).

Cons:

Vaccines dont always work, sometimes they dont give you immunity.

Sometimes you can have a bad reaction to the vaccine such as swelling, or mabye fever.

Antibiotics kill (or prevent the growth of) bacteria inside a living organism, differenant types of antibiotics are for different bacteria.

Antibiotics dont however kill viruses. As they reproduce by using our own body cells antibiotics will not stop them from reproducing as antibiotics stop patogens (foreign microorganisms) from reproducing not attack our own body cells where the viruses are reproducing.

Antibiotic resistant bacteria:

Bacteria can mutate to make them resistant to our antibiotics. This means that if you treat a disease…
