I have not heard of the FDA approving a covid vaccine. I know these rumors started at the beginning of the pandemic, but let's remember that there are a lot of lies on social media and forums. The FDA has not made anything public about covid vaccines, so there is no evidence that they have approved them. I worked with this company several years ago, and I know that the FDA never mentioned vaccines in their activities. I received a letter from them a few months ago, and I am concerned about this. I read about it in the article
