Jennifer,

Thank you for posting the link. I have several serious heart problems, low IgM, hypoxia with unknown cause. I am on oxygen and self isolating most of the time except for appointments. All my doctors tell me to get the booster. I did not have side affects from the two Pfizer vaccines, but I’ll get J&J this time. The more I read about mRNA vaccines the less comfortable I am. I will be flying to Mayo in January and I need some protection.
