The number of viruses seem to be increasing - ebola, zika, covid-19 etc - and I'm becoming increasingly concerned that we 're becoming ever more reliant on vaccines's. I'm not a scientist, so not really sure what a vaccine is or what it is made of, but I like to keep my body is as natural a state as possible, so don't like putting ever more stuff into it.
I think we need to be reflecting on human behaviour that encroaches more and more on the animal environment, and what we can do to reduce it. Population growth, Insecticides, deforestation, meat eating should all be reduced.
