Section 4: Considerations from the CDC (see https://www.cdc.gov/vaccines/covid-19/downloads/pre-vaccination-screening-form.pdf)
History of thrombosis (blood clots)
• If you have a history of an immune-mediated syndrome with thrombosis (blood clots) and thrombocytopenia (low platelets), such as heparin-induced thrombocytopenia (HIT) in the past 6 months, you should receive another FDA-authorized COVID-19 vaccine (i.e., mRNA vaccine), NOT the Janssen COVID-19 vaccine. Please talk to your doctor or healthcare provider.
Administration of Janssen COVID-19 Vaccine with other vaccines
• You should wait at least 14 days after getting any other vaccine before getting a COVID-19 vaccine.
• You may receive a COVID-19 vaccine if you have had a COVID-19 infection in the past.
• If you have a COVID-19 infection now, you should wait until you are better and have completed your isolation period before getting a COVID-19 vaccine.
Quarantine due to exposure to COVID-19 or travel
• If you are in quarantine because of COVID-19 exposure or because of recent travel, you should wait to complete your quarantine before getting a COVID-19 vaccine.
Monoclonal antibody or convalescent plasma treatment for COVID-19
• If you have received either of these treatments, you should wait at least 90 days to get a COVID-19 vaccine
Special populations: immunocompromised, pregnant, or breastfeeding
• A COVID-19 vaccine may be administered to immunocompromised individuals (including people with HIV and those on immunosuppressive medications) and to women who are pregnant or breastfeeding, BUT the vaccine has not been fully studied in these populations.
• If you are immunocompromised, pregnant, or breastfeeding consider talking with your doctor before getting a COVID-19 vaccine
If you have any additional questions after reviewing the above information, talk to your doctor or healthcare provider before getting the JANSSEN COVID-19 Vaccine.
