April 16, 2021 COVID Vaccine Update- Johnson & Johnson

Johnson & Johnson vaccines remain on pause as the FDA reviews evidence of rare blood clots. The Moderna and Pfizer vaccines have not been linked with any concerns and continue to be administered. During calls on 4/14 and 4/15, physicians and vaccine researchers at the CDC emphasized that the number of reported cases has been very rare (less than 1 in 1,000,000 people). The reason for the temporary halt in vaccination is to thoroughly investigate whether additional cases of clots have occurred. The goal is to allow people to make informed decisions prior to receiving a vaccination with the Johnson & Johnson (J&J) product. It is the expectation of our Health Department that within the next 2-3 weeks, vaccinations with J&J will resume.

Of the 6 cases of cerebral blood clots reported among the 6.8 million people who have received the J&J vaccine, all were women under age 50 and happened within 2 weeks of vaccination. There was no association with pregnancy or birth control (1 of the 6 women took birth control pills and none were pregnant).> Read More
