RW > CDC had on their own website info about vaccine trial lengths in which they stated takes around 15 years before being released and approved. During COVID- the page was still available but upon clicking the link it said “site under maintenance”. Soon after the page was completely removed and led to error not found.
this is a great example of an attempt to rewrite history. See below. I think you would need to look up halochos on lashon hara to see how you need to compensate CDC for your post.
I googled for CDC vaccine trial lengths and my first click went to CDC page that had a link to a page on historyofvaccines org (that is an outside page) that has first paragraph: Vaccine development is a long, complex process, often lasting 10-15 years, and involves a combination of public and private involvement.
Before that, there is a note added in May 2022:
Many anti-vaccine people and organizations are not presenting the information in this article in full context. The article below mostly covers vaccines before the current COVID-19 pandemic. Please see the section on the COVID-19 pandemic and Operation Warp Speed for information on the COVID-19 vaccines.
