I’ve never had the mRNA vax, but did have one shot of J&J’s Covid vax. I’ve had Covid twice, last in Nov/Dec 2021, the Delta variant which almost killed me, had pneumonia with it. Didn’t go in hosp as I was afraid to, no matter what. I had oxygen at home already, antibiotics for the pneumonia, and some other treatments. Then I had have LC ever since. I research all the time. I would take the Novavax Covid vax as it’s not a mRNA vax, but I can’t find it locally. That where I stand at present, while I try to treat the damaged and destroyed mitochondria with certain supplements as I’m exhausted all the time. I only go out of house for medical appts and always mask up with N95 mask and glove up with clean white cotton gloves, when I go to appts.
