How long does it take for the side effects of the covid-19 vaccine to show?
With the rollout of covid-19 vaccine comes a surge in concern on its side effects such as body pain, fever, fatigue, headache, diarrhea as well as pain, swelling, and heaviness on the injections site. Onset of these common side effects of covid-19 vaccine usually manifest within the day of receiving the shot, or it can even be after 2 to 3 days.
These side effects of covid-19 vaccine is the result of the body's immune response triggered by the vaccine jab. However, it is worth noting that since the vaccine does not contain the live SARS-CoV-2 virus, it in itself can not cause the infection.
These side effects are usually mild to moderate, lasting just a few days. Management of covid vaccination side effects is symptomatic treatment which focuses on alleviating symptoms such as taking over-the-counter paracetamol or acetaminophen to bring down fever.
On the other hand, rare but potentially deadly adverse effects such as anaphylaxis which is a severe form of allergic reaction towards the vaccine can manifest quickly. Thus, people who received the jab are asked to stay in the vaccination site for a predetermined amount of time so as to catch the onset of its symptoms such as difficulty of breathing, swelling of tongue or lips, and hypotension. This way, should anaphylaxis appear, it can be managed quickly and timely while on site.
Among the vaccines developed for covid-19, Pfizer and Moderna have been publicized to have more potent side effects, although it isn’t uncommon for other available vaccines to have their fair share of adverse reactions. Astra-Zeneca, for instance, is currently facing speculation due to its possible link to the development of life-threatening blood clots, although it has been claimed that such correlation is unfounded and vaccination benefits outweigh any potential risk.
As compared to the initial dose of covid-19 vaccine, the second dose usually triggers a stronger immune response.
