Another San Diego County resident has succumbed to COVID-19 in a second so-called local "breakthough" case. In so-called coronavirus breakthrough infections, fully vaccinated people get the illness anyway, despite the fact that the vaccines typically offer strong protection against severe disease. There are rare cases, however, that result in hospitalizations and, rarer still, deaths. On June 9, a county spokesman said an "older" San Diego woman who was fully vaccinated and had "many pre-existing medical issues" and was sickened by the coronavirus and later died.
