Dear all, my mum, who is in her mid 60s had had an allergic reaction to penicillin and some other antibiotics which we cannot recall the name about 10 years ago. The allergic was quite bad, she was in a daze and there were rashes all over. Is she suitable for covid vaccination? Also, I noticed that many medical publications suggest that Ethanol is more effective than Isopropyl alcohol in inactivating the virus causing covid, is that true? Lastly, it seems like many people reported long term symptoms after they 'recovered' from covid, such as brain fog, scarring of lungs and etc. How would we be certain that the dead RNA cells of the covid in the vaccines would not cause all these in the long haul?
