We had a bad experience last week .My husband was recently offered a chance to take part in a clinical trial as he has prostate cancer and other treatments haven't worked . 6 weeks ago we went down to Sydney (a 2 hour trip each way ) to meet the professor in charge of the trial .No mention was made of vaccinations or PCR tests ,we were treated warmly and asked to return in a month . Last week we went back with the expectation of my husband undergoing routine blood tests and to be accepted into the trial .We arrived at the clinic to a full waiting room and went up to the reception desk to say we were there ,the receptionist immediately asked if we were vaccinated ,when we said no the professors assistant suddenly appeared and we were told to go out into the corridor . the assistant then said he hadn't realised we wouldn't be vaccinated ,so i said why wasn't any of this mentioned previously . He asked if we would have PCR tests -i think he meant lateral flow ,he kept referring to it as a Covid swab .Anyway we refused ,he went away 3 times to speak to the professor and we were told my husband could not be seen .The assistant kept going on about the Covid swab -i told him none of the tests could detect Covid and they were using deception and misleading people i got very angry and said a few more things . Anyway we left and drove home .My husband sent an email to the professor the next day expressing his opinion and disappointment . he received a short reply stating that he could not accepted into the trial without continuous PCR tests or being double vaccinated . My husbands option is to go back to the hospital cancer clinic that referred him for the trail ,but i have a feeling their rules will have changed too . i was interested in how the participants in the trial being vaccinated would affect the results of the 2 treatments being studied .The feeling of being cast aside as a 2nd class citizens was not a pleasant t feeling .
