Many of you out there reading my blog, might be wondering what I was wondering - "Now that a vaccine has come, yet it causes severe allergic reactions, etc." So, this post is especially for all those curious minds ! Severe allergic reactions in many people who received the COVID - 19 vaccine produced by Pfizer and BioNTech maybe due to a compound in the packaging of the mRNA that forms the vaccine's main ingredient.
