RE: I'll take my natural immunity 🖼 any day over vaccines💉
Actually it was advances in sanitation and public health (such as more widespread handwashing, clean drinking water, etc.) that started the decrease of various diseases. Vaccines for them came on the scene after the illnesses were well in decline. The vaccines may have helped, but they can't take all the credit.
They surely do not have to take all the credit. But they are a huge part of the medical evolution.
