Her doctor told her that the steroids have probably counteracted the vaccine and that she may have to wait for 5 to 6 weeks and start the process all over again. Caller stated that she doesn't want to screw something up by getting the second one, but that she doesn't want to not be vaccinated. She was inquiring if it was ok for her to get the second dose of the vaccine and if the steroids could have affected the efficacy of the first vaccine. Caller reported that she was so disillusioned, that she has been trying to get hold of the county where she received her vaccine, emailing them, but has not been able to get hold of anyone. She stated that last night, 14Mar2021 she was reading the information she was provided when she received her vaccine and found the number to Pfizer, so she reached out to see if we would be able to answer her question. Caller was unable to provide NDC number or expiration date as they were not listed on her vaccine card. Caller stated that she was not an essential worker but she was a hair dresser and that she sees 10-12 people per day and was in close contact with them, within 6 inches. Caller stated that she sees people all day long and that she was lucky that she hasn't come down with it as she has asthma and was 62.
