CHICAGO (Reuters) – Some 25% of SARS-CoV-2 infections among Los Angeles County residents occurred in fully vaccinated residents from May through July 25, a period that includes the impact of the highly transmissible Delta variant, U.S. officials reported on Tuesday.- ADVERTISEMENT –<\/p>\n\n\n\n
The data, published in the U.S. Centers for Disease Control and Prevention’s weekly report on death and disease, shows an increase in so-called “breakthrough” infections among fully vaccinated individuals.<\/p>\n\n\n\n
The CDC is relying on data from cohorts, such as the Los Angeles County study, to determine whether Americans need a third dose of COVID-19 vaccines to increase protection. Government scientists last week laid out a strategy for booster doses beginning on Sept. 20, pending reviews from the U.S. Food and Drug Administration and the CDC.<\/p>\n\n\n\n
The new data released on Tuesday involved more than 43,000 reported infections among Los Angeles County residents aged 16 and older. Of them, 10,895, or 25.3%, occurred in fully vaccinated persons, 1,431, or 3.3%, were in partially vaccinated persons, and 30,801, or 71.4%, were in unvaccinated individuals.<\/p>\n\n\n\n
The vaccines did, however, protect individuals from more severe cases. According to the study, 3.2% of fully vaccinated individuals who were infected with the virus were hospitalized, just 0.5% were admitted to an intensive care unit and 0.2% were placed on a ventilator.<\/p>\n\n\n\n
Among the unvaccinated who fell ill, 7.5% were hospitalized, 1.5% were admitted to an intensive care unit and 0.5% required breathing support with a mechanical ventilator.<\/p>\n\n\n\n
In addition to the LA County data, the CDC on Tuesday released an update on the HEROES cohort study among healthcare workers that showed a significant drop in vaccine effectiveness among vaccinated frontline workers in eight states who became infected with the coronavirus.<\/p>\n\n\n\n
Vaccine efficacy during the period of the study when Delta was predominant fell to 66% from 91% prior to the arrival of the Delta variant, according to the report.<\/p>\n","protected":false},"excerpt":{"rendered":"
