Australia here.
My Father in Law beat Leukemia about 18 months ago after a 2 year battle. As we are aware, you're never totally out of the woods. He now has a blood problem that was brought on by some delayed reaction to the chemo. In order for treatment, they say he has to have the vaccination first. I was blown away, does this sound right? BTW, the treatment of the Chemo reaction, is a low dose Chemo tablet. Doesn't sound right to me.
Obviously that's fucked. Who told you that? Your GP or the admin cunts at a hospital? If it's your GP I'd get a second opinion. If it's a Hospital your options are a bit limited as I don't think we have hospitals that operate outside of government interference. I think you'll need to find a based doctor if this continues to be a problem.
As far as it sounding right legally, I don't know. The government controls healthcare here and does whatever the fuck it wants. The law changes every day to suit those in power. If you have the money and it's not as simple as finding a new GP I would seek legal counsel.
Edit: Hang on a minute. Now that I remembered. Why the fuck are they saying no jab no chemo when only 5% of the country is vaccinated and it's difficult to get one because of a lack of supply?
