FDA 在没有临床数据的情况下授权新的 COVID-19 疫苗
FDA Authorizes New COVID-19 Vaccine Without Clinical Data

美国食品和药物管理局 (FDA) 最近批准了 Novavax 的新型 Covid-19 疫苗,为美国公民提供了额外的疫苗选择。 这种疫苗使用基于蛋白质的技术,而不是像 Moderna 和辉瑞开发的那样使用信使 RNA。 动物测试结果支持 FDA 紧急批准 Novavax 的决定。 该疫苗针对的是变体 KP.3,而辉瑞和 Moderna 目前的疫苗则侧重于 KP.3.3。 Novavax 还计划继续生产基于 JN.1 的疫苗。 该疫苗适合 12 岁及以上人士,需要间隔 3 周注射两剂,或已接种疫苗的人士注射一剂。 值得注意的是,FDA 于 2023 年宣布结束 Covid-19 公共卫生紧急状态,但将紧急状态声明持续到 2024 年底。尽管自 2022 年初以来 Covid-19 水平有所下降,但最近通过 废水分析以及与 Covid-19 相关的住院和死亡人数略有上升,但仍明显低于 2021 年和 2022 年的峰值。

The U.S. Food and Drug Administration (FDA) has authorized a new COVID-19 vaccine from Novavax, giving Americans an alternative to shots from Moderna and Pfizer.

Novavax’s protein-based vaccine will be available soon after regulators granted emergency authorization to the Maryland-based company for the product.

FDA officials said that animal testing data supported the decision.

“Today’s authorization provides an additional COVID-19 vaccine option that meets the FDA’s standards for safety, effectiveness and manufacturing quality needed to support emergency use authorization,” Dr. Peter Marks, who directs the FDA’s Center for Biologics Evaluation and Research, said in an Aug. 30 statement.

The FDA cleared vaccines from Moderna and Pfizer that are built on messenger ribonucleic acid technology (mRNA) earlier in the month.

Critics say that the agency should not be making an assertion about safety and effectiveness in the absence of clinical trial data.

The assertion rings hollow when FDA has not required manufacturers of the mRNA biological [products] to provide scientific evidence to the public that safety and effectiveness has been demonstrated,” Barbara Loe Fisher, co-founder and president of the National Vaccine Information Center, told The Epoch Times previously via email.

Novavax President and CEO John C. Jacobs said in a statement that the company’s vaccine showed “robust cross-reactivity against JN.1 lineage viruses” in animals.

JN.1 was displaced in the spring by KP.3 and other variants, according to sequencing performed by the U.S. Centers for Disease Control and Prevention.

The CDC estimates that KP.3 and the closely related KP.3.1.1 caused about four in 10 cases in the two weeks ending Aug. 3. The agency estimated that KP.3.1.1 became the dominant strain by the end of August.

The Pfizer and Moderna vaccines target KP.3.

FDA officials initially advised manufacturers to target JN.1 but later recommended they target KP.3.

Because Novavax’s vaccine is built on different technology, it takes longer to manufacture than the mRNA shots. Company officials told FDA advisers over the summer that they were planning to continue manufacturing a JN.1-based vaccine and believed it would perform well against KP.3 and other strains from the JN.1 lineage.

The authorization is for people aged 12 and older. People who have never received a vaccine can get two doses of Novavax’s vaccine about three weeks apart. People who have received a vaccine before can get a single dose.

The Moderna and Pfizer vaccines are available for individuals who are at least 6 months old.

The CDC is recommending vaccination for all people aged 6 months and older.

The United States ended the COVID-19 public health emergency in 2023 but extended the emergency declaration under the Public Readiness and Emergency Preparedness Act until the end of 2024. The FDA issued the emergency authorization under that authority.

COVID-19 levels have plummeted since early 2022, although data from wastewater and other sources have indicated a recent uptick.

Twenty-eight states are reporting high levels of COVID-19 and two states are reporting very high levels, based on wastewater, according to the CDC. Hospitalizations and deaths attributed to COVID-19 have also been climbing, although the numbers are far lower than the highs recorded in 2021 and 2022.
