CDC warns Covid-19 vaccines might not protect people who are immunocompromised

By Elizabeth Cohen, CNN

The US Centers for Disease Control and Prevention on Friday warned people who are immunocompromised that the Covid-19 vaccine may not have been effective for them and encouraged them to take precautions as if they were not vaccinated.

“People who are immunocompromised should be counseled about the potential for reduced immune responses to COVID-19 vaccines and to follow current prevention measures (including wearing a mask, staying 6 feet apart from others staying they don’t live with, and avoiding crowds and poorly ventilated indoor spaces) to protect themselves against COVID-19 until advised otherwise by their healthcare provider,” according to the CDC’s website.

The CDC did not go so far as to tell the millions of immunocompromised people in the US to get an additional shot of a Covid-19 vaccine, noting that “the safety, efficacy and benefit of additional doses for COVID-19 vaccines in immunocompromised persons continues to be evaluated.”

A federal official told CNN that “CDC is looking into ongoing research exploring the possibility that immunocompromised could benefit from an additional dose.”

Some immunocompromised people have, on their own, received additional doses of the vaccine, and a study last month by Johns Hopkins researchers suggested that an extra shot may help increase Covid-19 antibody levels for some organ transplant recipients who did not have a full response to their original vaccinations.

On Sunday, Dr. Anthony Fauci, President Joe Biden’s chief medical adviser, acknowledged the reality that some people are acting ahead of official recommendations, noting that there are individual physicians “right now that are saying, ‘I want to go the extra mile with someone who might have a lower level of immunity.’ “

On Friday, the CDC said data suggest the response to the vaccines might be reduced for several groups, including organ transplant recipients, people who are receiving chemotherapy for cancer, people who have certain blood cancers, and people receiving dialysis or taking certain medications that suppress the immune system.

The CDC’s Advisory Committee on Immunization Practices is scheduled to discuss additional doses for immunocompromised individuals during its meeting on July 22.
