US reaches 50% fully vaccinated against COVID


White House officials today said 50% of Americans have now been fully vaccinated against COVID-19, with immunization levels up 11% from last week, as the nation’s Delta (B1617.2) variant activity surges.

Vaccination levels improve, studies show impact

Concerns over the more transmissible Delta variant and renewed pressure to get people vaccinated have pushed vaccination levels up. Cyrus Shahpar, the White House’s COVID-19 data director, said today on Twitter that vaccination levels have increased 44% over the past 2 weeks.

Meanwhile, a new study suggests that vaccination offers higher protection than previous COVID-19 infection, according to findings from Kentucky published today in Morbidity and Mortality Weekly Report (MMWR).

Researchers from the Centers for Disease Control and Prevention (CDC) and their partners in Kentucky examined hundreds of the state’s residents who had been sick with COVID-19 through June of 2021 and found that unvaccinated people had 2.34 times the odds of reinfection compared to those who were fully vaccinated.

Rochelle Walensky, MD, the CDC’s director, said in a statement, “If you have had COVID-19 before, please still get vaccinated.”
