- Expected side effects of the coronavirus vaccine are things like fever, fatigue, chills, and pain at the injection site, according to the CDC.
- However, a rare side effect of the coronavirus vaccine that some people have experienced is a lump in the armpit of the arm in which they were vaccinated.
- Doctors and the CDC say this side effect of the coronavirus vaccine is rare and nothing to be concerned about either.
As a growing number of states report the first cases of many more transmissible COVID-19 variants, it has now become a race against time in the US to administer as many doses of coronavirus vaccines as possible.
This was already the case, of course, but now any delay in administering the first COVID vaccine doses to humans runs the risk of prolonging exposure and vulnerability to the possibility of being infected by one of these newer COVID strains. In this sense, the World Health Organization says that in Africa, the newer, more contagious COVID strain is the cause of an increase in COVID infections and deaths. And that South African strain, known as B.1.351, has already been identified in the US, with South Carolina on Thursday confirming two cases in adults with no known travel history or connection to each other. All of this is to reiterate how important it is that the rollout of the COVID vaccine continues at the rapid pace it is now going on – in fact, an average of 1.35 million doses of coronavirus vaccines are already being delivered per day in the U.S. Bloomberg vaccine tracker.

That said, there may still be plenty of people who aren’t necessarily sure what to expect after getting their COVID shots, such as what the side effects might be. The CDC has said the expected side effects are things like fever, chills, fatigue, and pain at the injection site, all of which are the normal response to your body building up immunity against the coronavirus. But there is also one other side effect that you should be aware of – a rare one, but one that may cause you to panic.
One of the side effects that has not been much talked about is that some people have developed a lump in the armpit of the arm in which they received their COVID injection. If you’re involved in this don’t worry – this is rare, for example, but doctors also say this reaction is nothing to worry about at all.
According to the CDC, these armpit lumps usually appear 2-4 days after vaccination and usually last up to a few days. In addition, this side effect appears to be quite rare. “Reports of lymphadenopathy were unbalanced, with 1.1% of subjects in the vaccine group and 0.6% in the placebo group reporting such events,” explains the CDC.
In the same vein, Dr. Purvi Parikh – an immunologist at Allergy & Asthma Network – stated in a recent interview that swollen lymph nodes are one way the body tends to show that it is building an immune response. According to Dr. Parikh, your lymph nodes contain immune cells and the lymph nodes in your armpit swell because they are closest to the injection site in your arm.
