Are immunocompromised individuals more vulnerable to COVID-19?
People who are immunocompromised in a manner similar to those who have undergone solid organ transplantation have a reduced ability to fight infections and other diseases, and they are especially vulnerable to infections, including COVID-19.
Can a weakened immune system increase the risk of COVID-19 infection?
A weakened immune system or other conditions such as lung disease, obesity, advanced age, diabetes and heart disease can put people at increased risk for coronavirus infection and more severe cases of COVID-19.
Can I get the COVID-19 vaccine if my immune system is compromised?
CDC recommends that people with moderately to severely compromised immune systems receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of Pfizer-BioNTech COVID-19 vaccine or Moderna COVID-19 vaccine.
How long are immunocompromised people contagious during the COVID-19 pandemic?
Some severely immunocompromised persons with COVID-19 may remain infectious beyond 20 days after their symptoms began and require additional SARS-CoV-2 testing and consultation with infectious diseases specialists and infection control experts.
How does exposure to COVID-19 increase the risk of infection?
The risk of SARS-CoV-2 infection varies according to the amount of virus to which a person is exposed. Once infectious droplets and particles are exhaled, they move outward from the source. The risk for infection decreases with increasing distance from the source and increasing time after exhalation.
