"If it's in the skin, you might see a skin rash if it's in the nervous system, there might be issues with pain, or inability to move if it's the lung, then this individual might wheeze. ![]() "So there might be a sort of cross-reaction, where those immune responses recognize proteins within the individual," he explains. But in some people, Gomez-Duarte hypothesizes, some of that response gets directed to proteins that the individual has in the skin, or in blood vessels, or in the ears, lungs and heart. Gomez-Duarte says that normally, when a person receives a vaccine, an immune response is stimulated that directs antibodies against antigens that were injected into the body, building up your resistance to a virus. So how to explain the "rare" cases, as Gomez-Duarte puts it - and what to do if you yourself end up in one of these ear-ringing, head-pounding situations? Only a small number of individuals have reported experiencing problems with hearing and vertigo, Gomez-Duarte says, and most COVID-19 vaccinations proceed safely, with mild effects. ![]() Like Pfizer and Moderna's COVID-19 vaccines, the main side effects of the J&J shot are pain at the injection site and. Oscar Gomez-Duarte, the division chief of infectious diseases at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo. Moderna says 9.7 of their participants felt fatigued and 4.5 got a headache. Most side effects are mild and should not last longer than a week, such as: a sore arm from the injection. There's one more reassuring factor to keep in mind here: The frequency of these more unusual effects is pretty low, says Dr. Like all medicines, the COVID-19 vaccines can cause side effects, but not everyone gets them. Right now, we just don't know for sure, one way or the other. After getting the jab, individuals might simply be more attuned to the minutiae of how they're feeling physically - and, therefore, be prone to noticing more "symptoms," including small things that might've happened anyway.Ĭonversely, it may also be the case that some of these side effects do end up correlating with the vaccine - particularly as our understanding of these issues evolve and we get more data, Adams explains. That's especially since mindset may play a role, Adams explains. Information about things like vertigo and ear-ringing are still being collected on a mass scale and we still can't say with certainty that these more unusual effects are causally tied to the vaccine. Unlike the much more common COVID vaccine side effects - like fever, chills, and headache - there isn't really great data about these unusual cases, Adams explains. ![]() To start, she says, we simply don't know whether these weirder symptoms are really linked to the vaccine at all. Lisa Adams, the dean of public health at the Dartmouth Geisel Medical School, says in order to answer that question, we need to take a step back and be careful about our assumptions. The time is particularly ripe for all such vaccine-side-effects-discourses: With the Johnson & Johnson COVID-19 having been put on pause due to concerns over (rare) reports of blood clots, you might be wondering what to make of these serious and not-so-serious off-kilter cases.ĭr.
