In a world starved for any fresh data to help clarify the origin of the COVID-19 pandemic, a study claiming to have unearthed early sequences of SARS-CoV-2 that were deliberately hidden was bound to ignite a sizzling debate. The unreviewed paper, by evolutionary biologist Jesse Bloom of the Fred Hutchinson Cancer Research Center, asserts that a team of Chinese researchers sampled viruses from some of the earliest COVID-19 patients in Wuhan, China, posted the viral sequences to a widely used U.S. database, and then a few months later had the genetic information removed to “obscure their existence.”

The US National Institutes of Health (NIH) said on Wednesday it had begun a study to evaluate the immune responses generated by Covid-19 vaccines in pregnant or postpartum women. Pregnant women are at higher risk of complications including premature birth, high blood pressure with organ failure risk, need for intensive care and possible death, according to the NIH. A research study conducted in February in Israel showed that antibodies were detected in all 20 women administered with both the doses of the Pfizer/BioNTech vaccine during their third trimester of pregnancy and also in their newborns.

Medical workers move the body of a person who had died from COVID-19 at a hospital in Wuhan, China, on Feb. 16, 2020.
Thirteen genetic sequences isolated from people with COVID-19 infections in the early days of the pandemic in China were mysteriously deleted from an online database last year but have now been recovered.
Jesse Bloom, a computational biologist and specialist in viral evolution at the Fred Hutchinson Cancer Research Center in Seattle, found that the sequences had been removed from an online database at the request of scientists in Wuhan, China. But with some internet sleuthing, he was able to recover copies of the data stored on Google Cloud.
