Did you know that medication in your system does not break down in the sewage treatment process and is released into the oceans where it affects the sea life?

So looking after our own health and reducing the need for pharmaceuticals in our own lives, will have a beneficial effect on the environment. That’s one good reason why building resilience and immunity through vaccination is a good idea.
