Doctors, Medical Experts Divided on Second COVID-19 Booster
There has been notable disagreement in the medical community about a fourth COVID-19 vaccine dose. The FDA last week authorized a second booster dose for older and immunocompromised individuals, as some agency officials did not support the idea. The FDA made the decision without meeting with its advisory committee, as it had ahead of its recommendations on the previous COVID-19 vaccine doses. The CDC followed in the footsteps of the FDA and authorized a fourth dose as well. Reports say the agency also did not discuss the move with its own advisory team of vaccine experts. Now, a growing number of doctors are speaking out against the decisions - leaving people confused about whether they should get another vaccine dose. Dr. Julie Morita, a member of the CDC's advisory committee to the director, and the executive vice president of the Robert Wood Johnson Foundation, joins Cheddar News' Closing Bell to discuss.
