Mary Altaffer / AP Originally published on April 13, 2021 5:12 pm The McLean County Health Department (MCHD) is suspending use of the Johnson & Johnson COVID vaccine after federal regulators recommended the vaccine be shelved because of rare reports of potentially dangerous blood clots. Illinois State University officials said Tuesday the weekly clinic the health department hosts on Thursday will switch to the Pfizer vaccine, which requires a second dose. The Pritzker administration also said it would follow the federal guidance against using the Johnson & Johnson vaccine. MCHD public affairs coordinator Marianne Manko said the health department received a “very small amount of the vaccine” prior to this week. The one-dose J&J shot was used primarily for targeted populations that health officials consider harder to reach, including college students and rural residents.
