美國加洲在施打不到33萬劑Moderna的疫苗後,因為施打疫苗後的過敏反應數量高於正常水平,美國加州衛生官員已經要求暫停接種 Moderna 的疫苗。 Moderna 以及聯邦衛生和藥品官員正在評估這件事。挪威在施打Pfizer 48,000 劑疫苗後,死亡人數高達33人,雖然挪威政府說明,死去的多為安養院老人,因此可能與疫苗無關,但是仍然引起挪威社會對疫苗安全問題的驚恐,因為其他的疫苗也都為安養院老人施打。
The most significant outbreak is among the state’s urban and rural Latino populations. Among cases where the patient’s race is known, 55 percent of California’s infections have been in Latinos, who make up just under 40 percent of the state’s population. Latinos and Hispanics are bearing the brunt of the pandemic not only in California but along the entire West Coast, including Oregon (38 percent of cases where the patient’s race is known vs. only 13 percent of the population) and Washington (44 percent vs. 13 percent).
In California, the infected are predominantly low-income, densely housed front-line service workers. Leaving home to work each day, they are exposed to the virus. When they return, it spreads in their households, which are often multigenerational. The consequences are striking. In late April, professor Gabriel Chamie and colleagues from the University of California at San Francisco studied 3,953 individuals living in a single census tract in the Mission District of San Francisco. While the estimated prevalence of infection among non-Latinos in this population was 0.2 percent, for Latinos, it was 3.9 percent — nearly 20 times higher.
Another of California’s sub-epidemics has been among people who, upon the state’s reopening, have failed to treat the virus as real and dangerous. They seem unable or unwilling to distance themselves from others and wear masks begrudgingly, if at all. From the beaches and bars of Southern California to backyard barbecues in the Central Valley to a fraternity house in Berkeley, failure to heed safety warnings has inexorably pushed the incidence of infection higher.
In addition, there have been explosive outbreaks in institutional settings in California. As in the rest of the country, California’s long-term care facilities, such as skilled nursing and assisted-living facilities, have been particularly vulnerable; overall, 47 percent of Californians who have died of covid-19 have been nursing home residents.
