FDA Says Some Americans Shouldn't Get Another COVID-19 Shot
[Epoch Times] Some Americans cannot receive another COVID-19 vaccine dose, U.S. regulators said on April 18, as they made sweeping changes to the vaccine system.

The U.S. Food and Drug Administration (FDA) announced the changes, including replacing the old Pfizer and Moderna vaccines with updated bivalent shots that had previously only been available as boosters. Regulators are also scaling back the number of recommended doses for most individuals, including people who haven’t received a shot.

The FDA authorized the original vaccines in late 2020 based on clinical trial efficacy data. The original vaccines targeted the Wuhan virus strain, which hasn’t circulated since 2020. The updated bivalents target the Wuhan strain and the BA.4 and BA.5 subvariants of the Omicron strain. The subvariants were displaced in 2022.

Regulators authorized the bivalents as boosters in 2022 despite no clinical trial data being available. In letters formally announcing the bivalents as replacing the old vaccines, the FDA made clear that scientists aren’t sure whether the bivalents protect against COVID-19.

Dr. Harvey Risch, professor emeritus of epidemiology at the Yale School of Public Health, said that he sees the vaccines as largely unnecessary. "The current vaccines are out-of-date, any new ones will be out-of-date by the time they are generally available, and mostly everybody already has SARS-CoV-2 antibodies anyway," Risch told The Epoch Times via email. "At this point, the vaccines are thus not generally useful products for serving a public health function."

The newly rolled out system is for the spring, as officials are planning to meet over the summer to discuss a fall regimen. They plan to adapt COVID-19 vaccines to the influenza model, updating strains in the vaccines each year.
