California has reported 3,620 so-called breakthrough cases of coronavirus infections in people who were fully vaccinated since Jan. 1, state public health officials said Wednesday. That is nearly 600 more breakthrough cases than reported just last week. Of those cases, at least 150 people were hospitalized and at least 20 died.
The 3,620 breakthrough cases represent 0.25% of the more than 1.4 million coronavirus cases reported in California from Jan. 1 to May 5. The 20 deaths make up 0.06% of the 35,677 COVID-19 deaths in that time.
