Hi Allan
Except in trials to make sure it is safe there is no vaccine available for Covid, with the most optimistic being that one (Fully tested and certified) will be available by the end of the year. (But don’t hold your breath though)
See my post above about masks as it applies to homemade masks as well.
Not sure about Oz but in the UK there are exemptions to mask wearing if the person has problems, (Asthmatics etc.) and I would imagine something similar applies in Oz, (Yours like most developed country’s have a 1st world health system) so may be worth looking into.
Look after yourself, stay safe, and listen to the advice medical professionals NOT politicians and social media.
Bill
