Vaccines that are created with a killed version of a pathogen or with just a small portion of the pathogen aren’t enough to trigger illness. When someone receives such vaccine, it’s impossible for that person to fall ill for that particular disease.

Just a Tiny Part of the Virus

Attenuated or weakened vaccines still have the capability of causing illness for they could replicate though not well, mutation is also possible that may lead to virulent form of pathogen.

On the other hand, they’re designed in such way and attenuated too in an effort to lower this possibility. The reversion to virulent form is a challenge with some types of oral polio vaccine or OPV, which is the reason why only inactivated form or IPV is what’s used across the US.

To be Vaccinated or not?

It is essential to take into account that an attenuated vaccine may create severe health problems among individuals especially those who have weak immune system like cancer patients. These people might get a killed form of vaccine, assuming that there’s one available. Otherwise, their doctors might suggest against vaccination. In this case, individuals are relying on their immunity as a way to protect themselves.

At the end of the day, your doctor will tell you the best course of action to take.
