Residents of long-term care institutions, individuals 65 and older, health care workers, and immunocompromised persons are among those who should be monitored for a possible additional injection.
A CDC official told an advisory committee on Wednesday that there is presently no evidence to support a recommendation for coronavirus booster injections.
The CDC’s Sara Oliver told the Advisory Committee on Immunization Practices that authorities would continue to examine data to determine whether a booster injection is required in the future. A prescription for booster doses would most likely “occur” only after “evidence of decreasing protection against disease, such as reductions in vaccination efficacy” or the discovery of a “variant of concern significantly affecting vaccine protection,” she said in a presentation.
The presentation was intended to assess what variables the advisory committee will be looking for if it has to make future recommendations for booster injections. Before making any judgments, committee members agreed that additional information was required.
Oliver noted that certain populations might need a second injection while others may not. Residents of long-term care institutions, individuals 65 and older, health care workers, and immunocompromised persons are among the particular groups to be monitored, according to her.
She said that future talks about extra doses should take global vaccination availability into account.
Pfizer CEO Albert Bourla told Axios that an extra dosage would likely be required “sooner rather than later,” sparking debate over whether or not booster injections will be required. Booster doses, he added, may be required as early as September for the first vaccination recipients.
Leading infectious disease specialist Anthony Fauci has also said that booster injections are likely to be needed.
However, many issues remain unanswered, according to public health experts, before recommendations for the injections may be made.
