Skepticism is great but without knowledge that is lethal weapon. Everyone heard about vaccine bad for health. Is it really true? What science say about that, let's look at the facts and scientific way.
Vaccines are protecting(not %100) us from diseases, pandemics etc. How is possible that? Because vaccine content vary chemical. (Chemicals are not bad for us. Everything occurs chemicals even human body, too) Every vaccine contents different amount chemicals and some vaccines does not contain some chemicals. Indeed, this chemicals(e.g mercury[thimerosal], aluminium, etc ) prevent the growth of dangerous microbes. But some media, people say it is bad for health in children. There is no evidence that thimerosal in vaccines are dangerous and autism [1][4][5] What about aluminium and why aluminium are using in vaccine? Aluminium is improving immune system for fighting with bacterias, microbes. Low dosage aluminium is necessary for being healthy. Aluminium, contained 4.4 milligram in vaccine of infant formula which is less than received by their diet and infants ingest about 7 milligrams via breast-fed or about 38 milligrams via infant formula. So, i heard what said to me that is not prove for safety. For safety, vaccines contain low dosage of aluminium(you can see that, aluminium dosage in link 3 and 6)Some study shows may be toxic in other species.[6] In human, studies in-progress. Aluminium linked to Alzheimer's disease which is accumulation of aluminium in brain. However, this is not directly linked to increased level of aluminium.[3] Indeed, aluminium is still in-progress. Too much, aluminium exposure may be harmful for human but it does not mean aluminium is bad for you. In toxicology, "The dose makes the poison" not itself.
So, what happened if we stop vaccination?
-Today, a lot of medical doctors have never seen measles. If we stop vaccination, measles spread again and a lot of people die[9]
-A lot of people died diphtheria in 1921 before the vaccine. Only two cases reported in 2004 and 2014. That is mean nearly diphtheria is destroyed.[9]
-German measles(rubella) in 1964-65 infected 12½ million Americans, killed 2,000 babies, and caused 11,000 miscarriages. Since 2012 15 cases of rubella were reported of CDC[9]
If you don't vaccinate, you are in danger and not just you in danger all around of you will danger. In 2013, for example several measles occurred in USA, mainly among groups with low vaccine rates.
Conclusion
Vaccine comes with a little risk but it provides huge advantage to protect disease. I think, benefits more than risks of vaccine. If you still have issues consult your medical doctor for best information.[8]
I am sorry if i made mistakes.
Have a nice day and stay healthy!
