Believe it or not, my intention was not to be an asshole right off the bat. I can tell that you are an intelligent person, and while I may have come off as an asshole with my spelling correction, I am attempting to give you helpful advice. In any argument, if you have a spelling mistake, it will automatically detract from your credibility. Am I flawless with my spelling most of the time? Heck no, but I try to proofread to make myself sound more believable.
On the one regarding profit margin, this is (mostly) untrue for a few main reasons: The first being that more than 1 in 100 unvaccinated people would get sick. This is simply untrue; even with people who are being inoculated to a disease, or given extremely small amounts of the virus to build immunity, about 1 in 50 or 2% become sick with it. Lets say people contract a virus, like, say, measles. The majority of people are not immune to measles, thus the amount of money for intensive care for 100 unvaccinated people would be much more than you say. And vaccines still are not as much as a profit as intensive care. Vaccines almost always prevent the possibility of intensive care, so hospitals would not make as much money. That was the point I was trying to get at; that vaccines prevent something that is much more of a monetary gain for medical institutions.
On the fact that fevers are common for vaccines, I have never heard of that ever happening but I will believe you on it because I have not researched it and I assume you have.
On your point on autism, you are partially correct. There is not 100% certainty on what the cause of autism is, but it is thought by many medical researchers that autism is caused mostly by genetics.
On my "knee jerk reaction" I'm not really sure what you mean here. It seems like an immature way to phrase something impulsive, but I don't really know. Please have better context in the future.
Lastly, there is the fact that it is absolutely indisputable that vaccines save more people than they harm. I am aware that you did not argue about this specifically, but I really need to get it out there. WHO (World Health Organization) estimates that the measles vaccine alone has saved the lives of 20.4 million people alone from 2000 to 2016. It is also estimated by WHO that 6 million people are saved by vaccines around the world annually. Last but not least, only 1 in 1 million children have an adverse reaction to a vaccine, a statistic also from WHO.
