1) Effectiveness of Covid-19 Vaccines against the B.1.617.2 (Delta) Variant (Bernal et al. 2021)

Only a slight difference in protection between alpha and delta, and the difference is greater after one dose vs. two doses.

2) Impact of circulating SARS-CoV-2 variants on mRNA vaccine-induced immunity in uninfected and previously infected individuals (Lucas et al. 2021 – Iwasaki lab)

3) Delta Is Driving a Wedge Through Missouri

Almost every COVID-19 patient in Springfield’s hospitals is unvaccinated, and the dozen or so exceptions are all either elderly or immunocompromised people. The vaccines are working as intended, but the number of people who have refused to get their shots is crushing morale.

The virus doesn’t care whether you’re a Republican or Democrat, or your race or religion. It doesn’t care about your ego or your anxieties, whether you believe in science or not, whether you trust vaccines or not.
