Another message doing the rounds on social media in 2020 and 2021 was that Covid vaccines would cause infertility. This was sometimes backed up by a quasi-scientific-sounding claim, that the Covid-19 spike protein was similar to a protein found on the placenta, and that antibodies against the spike protein would therefore also attack the placenta, resulting in infertility. There were no grounds for this claim. To think through its implications, if it were true, any woman infected with SARS-CoV-2 would develop antibodies to the spike protein and become infertile. This has not happened. There are also four other coronaviruses that infect humans, circulating mainly in the winter months, each with their own spike protein. There is no evidence that infection with these seasonal coronaviruses results in infertility.

Parents of autistic children are particularly [vulnerable to placebo effects](https://www.spectrumnews.org/features/deep-dive/trials-autism-treatments-placebo-problem/), says [Jeremy Veenstra-VanderWeele](https://www.spectrumnews.org/author/jeremy/), professor of psychiatry at Columbia University in New York who was not involved in the trial. The placebo effect is amplified when parents pay to participate or when the therapy is invasive, because parents are invested in having the treatment work, he says.

Eine unbeantwortete Frage blieb aber lange, warum diese Zellen überhaupt verschwinden.
