I just checked and none of the top four COVID-19 vaccines currently contain thimerosal nor aluminum adjuvant. I have been asking for that for many years now. Can the pharmaceutical companies now do that for all of the other vaccines, as well? The brains and intellectual capacities of the people of the world appreciate it. This could be a great "spin-off" of the pandemic, to eliminate those ingredients. Thank you. Gary Joseph Ordog, MD.
