@Nammu, thanks for sharing about the cause of your deafness. It's so awful that that happened! Far too many people have no clue how dangerous such diseases are, instead thinking the vaccines are always worse, or that they are fully protected because of others being vaccinated. Obviously, like you, my mom was born before the vaccine availability. She had awful cases of measles, mumps, and Scarlet fever that kept her home from school for months, one affecting her kidneys. At a point, they wondered if she might die. I think that period was even a bit traumatic for her.

I got the MMR vaccine as a very young child, but had to also again during university years. I recall during the latter them saying breakthrough cases were present from vaccines given during certain years. Since then, I've always kept up with vaccines and am happy I've done so, also getting additional (incl. a malaria one) before my travels to Asia in the 1990s. My mom, having gone through what she did as a child, instilled in my siblings and me a very pro-vaccine mindframe.
