Q: What are the ingredients in the vaccine, are they all safe or can they create other symptoms? Why don’t they tell us what is in the vaccine?

The ingredients in all of the FDA reviewed Covid vaccines (as well as any vaccine or drug that is reviewed by the FDA) is made known in the FDA application, there are no hidden ingredients and there is no mystery. However, the specific manufacture process (think like the recipe of a special dish) is not disclosed to the public because these are protected and proprietary intellectual property (like the recipes of many popular foods). The ingredients in all the current FDA authorized COVID-19 vaccines have been found to be safe, especially as hundreds of millions of people have received these vaccines safely.
