> So why is "get you vaccine and booster" in the first sentence?
It's literally there in the second sentence -
"The odds of illness severe enough to warrant hospitalization are dramatically lowered if you stay up to date on your COVID-19 vaccine, including a booster dose."
“Vaccine effectiveness of the mRNA vaccines to prevent COVID-19-associated hospitalizations included: 85% (95% CI: 82 to 88%) for 2 vaccine doses against Alpha; 85% (95% CI: 83 to 87%) for 2 doses against Delta; 94% (95% CI: 92 to 95%) for 3 doses against Delta; 65% (95% CI: 51 to 75%) for 2 doses against Omicron; and 86% (95% CI: 77 to 91%) for 3 doses against Omicron.”
Less effective, but not ineffective, especially after a booster.
