Despite experiencing these side effects, Haydon remains an advocate of the vaccine. The 29-year old Seattle native had previously spoken about the vaccine on CNN and CNBC, stating that he’d even volunteer to be exposed to SARS-CoV-2 – the pathogen behind the pandemic – if researchers want to see if the vaccine is actually effective.
As Haydon pointed out to STAT News, the whole purpose of the study he was a part of — known as a Phase 1 clinical trial — was to be able to find the right dose of the vaccine moving forward. A proper dosage of the vaccine would allow immune cells to produce antibodies with the least amount of side effects in the body.
In Moderna’s 45-person study, four participants, including Haydon, experienced what are known as “Grade 3” adverse events. These are side effects that are severe or medically significant but not immediately life-threatening. Neither the National Institute of Allergy and Infectious Diseases, which is running the trial, nor Moderna has previously detailed the nature of these incidents.
Moderna, however, did disclose that three participants – likely including Haydon – received the highest dose of the vaccine candidate that was tested and had reactions involving their entire bodies. A fourth participant received a lower dose and experienced a rash at the injection site.
According to Haydon, when he was given the first dose, he experienced slight arm pain and had trouble lifting his limb beyond his shoulder, but he recovered within a few days....<<<Read The Full Article Here>>>...
