Vaccines weaken the immune system

It won't hurt a Bit: Immunizations

Natural infection with certain viruses can indeed weaken the immune system. This means that when children are infected with one virus, they can.t fight off other viruses or bacteria as easily. This happens most notably during natural infection with either chickenpox or measles. Children infected with chickenpox are susceptible to infection with certain bacterial infections (like .flesh-eating. bacteria). And children infected with measles are more susceptible to bacterial infections of the bloodstream (sepsis).

But vaccines are different. The viruses in the measles and chickenpox vaccines (the so-called vaccine viruses) are very different from those that cause measles and chickenpox infections (the .wild-type. viruses). The vaccine viruses are themselves so disabled that they cannot weaken the immune system. Vaccinated children are not at greater risk of other infections (meaning infections not prevented by vaccines) than unvaccinated children.
