Cases occurring 14 or more days after the second dose among those who received it (n=14,669) was even lower at 0.3%. Incident cases among unvaccinated residents (n=3,990) also decreased from 4.3% within 0-14 days after the first vaccination clinic to 0.3% at &gt;42 days after the clinic. The authors suggest that high vaccination coverage, along with existing mitigation measures, conferred a certain degree of herd immunity among unvaccinated residents.<\/span><\/li>\n<\/ul>\n<p><i><span style=\"font-weight: 400\">White et al.\u00a0(May 19, 2021).
