She commented it was like she could not talk either. She was scheduled to get the second dose on 12Mar2021. She was sceptical to get the second dose due to the effects. She was concerned and wanted questions answered before the 12th. She was confused and wanted to determine the cause of pain. She added making decisions was difficult for her.
