Quote Wikipedia:
The principle is popularly, but incorrectly, summarized as "the simplest explanation is more likely the correct one." The principle of Occam's Razor recommends selecting the competing hypothesis that makes the fewest new assumptions (aka postulates, entities). It is also important that the two hypotheses be equal in other respects; for instance, they must both sufficiently explain available data in the first place. It is in this sense that Occam's razor is usually understood.

<i>1) Instead of all this scientific mumbo-jumbo about physics and relativity that is imperfectly understood and nigh-impossible to prove outside of theory, it is much simpler to believe that God exists and that He controls all things.</i>

This explanation fails to sufficiently explain available data. For example, synchrotron radiation forming a beam is a relativistic effect you see in practive.

<i>2) Instead of assuming that some sort of invisible, all-powerful supernatural being exists and has some sort of mechanism from which he creates/controls all things, it is much simpler to believe that the Universe just exists, and it works according to a few basic laws from which we can derive how all other things work.</i>

God isn't really explaining anything in the world. Hence, Occam's razor can work here.

<i>Or, just to play devil's advocate,

Occam's razor says that either tens of thousands of scientists, businessmen, chemists, and engineers in the pharmaceuticals industry have ALL missed the possibility of negative effects stemming from these vaccines, or that certain key figures who have the data are silent so that the government can better control its people. Which is the simpler explanation?</i>

The simplest explanation is that you were eager to sell your new vaccine to the government and the healthcare companies and didn't want to invest more than minimal amount of money in testing that it's safe. Thus, a vaccine with flaws may have passed the not so thorough testing. Personally, I chose not to take the swine flu vaccine after seeing what it did to some people. After seeing that, I thought it might be better to have the swine flu than the vaccine. In addition, the vaccine used here was banned in US due to having an oil-based effectiveness booster component (Dunno the proper English term). Oil-based vaccine effectiveness booster components were banned in US after causing severe complications to US armed forces when used during the Gulf War. The medical companies produce 2nd rate crap vaccines like this because they are cheaper and faster to manufacture. It's better profits if the governments approve them. Simplest explanation is money, not a grand conspiracy.
