she always get sick with Moderna; chills; nauseous; not feeling well for two weeks; This spontaneous case was reported by a consumer and describes the occurrence of MALAISE (not feeling well for two weeks), ILLNESS (she always get sick with Moderna), CHILLS (chills) and NAUSEA (nauseous) in an elderly female patient who received SPIKEVAX NOS (SPIKEVAX NOS) for COVID-19 prophylaxis. Concurrent medical conditions included Immunocompromised. Concomitant products included COVID-19 vaccine prot. subunit (NVX CoV 2373) (Novavax COVID-19 Vaccine) and Influenza vaccine (Flu) for an unknown indication. On an unknown date, the patient received dose of SPIKEVAX NOS (SPIKEVAX NOS) (Intramuscular use) 1 dosage form. On an unknown date, the patient experienced MALAISE (not feeling well for two weeks), ILLNESS (she always get sick with Moderna), CHILLS (chills) and NAUSEA (nauseous). At the time of the report, MALAISE (not feeling well for two weeks) had resolved and ILLNESS (she always get sick with Moderna), CHILLS (chills) and NAUSEA (nauseous) outcome was unknown. It was asked if mNEXSPIKE was the new version of Spikevax as she saw on social media ads from Moderna that it was really pushing on mNEXSPIKE as a better choice for people 65 years and older. Then it was asked about efficacy of mNEXSPIKE per data of the clinical trial, it's side effects and if she should be getting it along with influenza vaccine. Patient was immunocompromised and was over 65 years old, at the later part of the call that she was over 70 years old. She had negative reactions with each of her Moderna COVID-19 vaccines she had received. It was asked about mNEXSPIKE availability in the US. It was stated she was looking at Novavax, which was a totally different company and totally different formula, because she always got sick with Moderna. However, she would always get Moderna because she had read that it was better than Pfizer for older people and immunocompromised people like her. She always got Moderna, even though it made her sick. She was looking, well, one time she got the Novavax, and it was amazing. She didn't get sick. It was like she didn't even have a shot, didn't feel the needle going in, didn't get a sore arm, didn't get sick. It was like nothing happened. But with Moderna there had been times she was like not feeling well for two weeks, like chills and nauseous and but to her that was kind of a good thing because she knew it was in her system. She didn't really want it all to be reported because she really wanted to continue Moderna because she thought it was more effective than Pfizer. But she really, really like getting the Novavax but she can't find any studies or comparisons of Novavax compared to Moderna. She was due for her vaccine and wanted to do it on Monday, so she was trying to make a decision. It was inquired if it was okay to receive the flu shot along with mNEXSPIKE on Monday as she typically didn't get the flu vaccine the same day she gets her Moderna COVID-19 vaccine considering her specific health conditions, if she could handle the two products at the same time but was considering doing such because she had a procedure coming up and had to have any vaccines taken care prior. Also, if it was better to wait since she was immunocompromised and elderly. It was asked that if so, does it affect the efficiency of both vaccines. It was stated, she was just wondering if adding the flu shot at the same time as the Moderna was going to lower the effectiveness of those vaccines. She was on some medications that hinder the effectiveness of the vaccines. After getting all these vaccines over the years that they were probably not helping enough and reading studies about the drugs that she was on. The vaccines didn't fare well up against the medicine she was on either. It was already diminished, but she was wondering if adding a flu shot onto that could her body handle dealing with two vaccines and building two different sets of antibodies at the same time. she had other procedure coming up and had to have any vaccines taken care of, so she had many weeks ahead of time. She had side effects after every Moderna. She had 13 vaccines and boosters so far for COVID. When she had Novavax, the one time she had no, no side effects at all. But then there was one time with Moderna when she had no side effects. She didn't know what that was about. But every other time she did. So that was just odd because she was all prepared for side effects and then it didn't happen. Treatment medication was not reported.
