Now, it's the CDC's turn. The panel is preparing to wrap up a two-day meeting on Wednesday, where it is deliberating a more specific set of guidelines regarding the booster jab and who will initially be eligible, and when.

Before we get into specifics, it's worth noting that after the first day of discussion, some of the advisors were so befuddled by the rationale for boosters that they suggested putting off the CDC's decision for a month to wait for more evidence. Such a decision would probably have driven the Biden Administration crazy.

According to the AP, "the uncertainties were yet another reminder that the science surrounding boosters is more complicated than the Biden administration suggested when the president and his top aides rolled out their plan at the White House last month."

On Wednesday, "the CDC panelists heard a series of presentations Wednesday outlining the knotty state of science on boosters. On one hand, the COVID-19 vaccines continue to offer strong protection against severe illness, hospitalization and death. On the other hand, there are signs of more low-grade infections among the vaccinated as immunity wanes."
