The United States Centers for Disease Control and Prevention warned immunocompromised people on Friday that the Covid-19 vaccine may not have worked for them and encouraged them to take precautions as if they were not vaccinated.
“Immunocompromised people should be made aware of the potential for reduced immune responses to COVID-19 vaccines and to follow current prevention measures (including wearing a mask, staying 6 feet away from others they do not live with. not, and avoid crowds and poorly ventilated indoor spaces) to protect against COVID-19 until advised otherwise by their health care provider, ”according to the CDC website.
The CDC did not go so far as to tell the millions of immunocompromised people in the United States to receive an additional injection of a Covid-19 vaccine, noting that “the safety, efficacy and benefits of additional doses for COVID-19 vaccines in immunocompromised people continue to be evaluated.
A federal official told CNN that “the CDC is investigating ongoing research exploring the possibility that the immunocompromised may benefit from an additional dose.”
Some immunocompromised people have, on their own, received additional doses of the vaccine, and a study conducted last month by Johns Hopkins researchers suggested that an additional injection could help increase levels of Covid-19 antibodies to some organ transplant recipients who have not had a complete response to their initial vaccinations.
On Sunday, Dr Anthony Fauci, chief medical adviser to President Biden, acknowledged that some people are acting before official recommendations, noting that there are individual doctors “right now who say,” I want to make an effort extra with someone who might have a lower immunity level.
The CDC said on Friday that data suggests the response to vaccines may be reduced for several groups, including organ transplant recipients, people who receive cancer chemotherapy, people with certain blood cancers. and people on dialysis or taking certain drugs that suppress the immune system.
The CDC’s advisory committee on immunization practices is expected to discuss additional doses for people with compromised immune systems at its July 22 meeting.
