4. Rare side effects
As with any vaccine, you can’t say that the MMR vaccine contains no side effects whatsoever. Bear in mind that even Aspirin or Xanax can come with their own set of side effects. You’ll struggle to find anything that you consume that doesn’t cause side effects. While the MMR vaccine can cause side effects, it is a very rare occurrence.
The odds of developing encephalitis following a dose of the MMR vaccine are one in three million. This is according to tests conducted by the United States Food and Drug Administration — or FDA. In contrast, the odds of developing encephalitis due to measles are one in a thousand. It is also unclear if the vaccines actually caused those “one in three million” cases or if they just developed coincidentally.
Remember, as the saying goes, correlation isn’t causation. You can find the Denmark study for yourself and review the data if you’re still skeptical.
