I reacted to the PEG, in my first Pfizer vaccine, with chemical sensitivity to products typically not bothersome to me for the last 10 years or so. Prior to that, since 1989, I could not be around perfumes, lawn chemical sprays, laundry detergents and softener fragrance, etc, etc, without getting severe headache, sore throat, nasal passage sores, insomnia. I was afraid that in getting the second dose, I would get even more sick. I have recovered since February 18 dose. I would be willing to get the second dose if I could recover in several weeks. I hope you understand that not recovering means withdrawing from life as I once had to do. I had itching for several hours following the injection, later, a painful lump in my armpit, below the injection site.
