They are very thoroughly tested at this point Nicky. I understand some hesitation back when they were first being given out but at this point... over 4 billion people (more than 50% of the entire global population) has had a vaccine dose. That's an absolutely massive amount of testing data. Probably more than any other vaccine or medication in history.

Yep and low salts will make you rather unwell - if your salts are low you can drink all the water in the world and you'll still be functionally dehydrated. That's why sports drinks have salts and electrolytes in them.
