Good morning,
a German friend has american relatives. She is in need of a trustable (english-written) link that tells, why Covid19-vaccines should be pretty safe even if they were developed in less than a year.
I read somewhere, that research on Corona-viruses did happen already for years (since SARS and MERS) and they could use all this research for this new Corona-virus now.
Thanks if you post a link or two I can forward 🙂 andi
