Covid-19 vaccine side effects show immune system responding properly

NEW YORK, 23 Feb 2021:

Side effects such as pain and swelling at the shot spot, fatigue, headache, fever and chills are common for Moderna and Pfizer-BioNtech Covid-19 vaccine receivers, CNBC said in a recent health report.

People who experienced such side effects may take over-the-counter pain pills after the vaccine shot to alleviate these symptoms, said the CNBC report, with reference to recommendations by US Centres for Disease Control and Prevention (CDC).

The report said it is normal for human bodies to experience such side effects as the immune system is set to form its preparation and protection against the virus through a process called “controlled inflammation” – which is the way the mRNA messenger vaccines work in.

To mitigate these side effects – which can be very serious in some cases – US CDC said people can take over-the-counter pain medications such as ibuprofen, aspirin, antihistamines or acetaminophen after getting the vaccine. However, to see a doctor for advice before taking medicine is also recommended by the agency.

The US CDC does not support the practice of taking these pills before getting shot, said the report, because it will weaken immune system’s response to the mRNA messenger vaccine.

In other words, the antibodies generated for people taking pain medicine before their shots are not as good as originally expected from the vaccine.

The US CDC also listed other ways for alleviating the vaccines’ side effects – including putting a wet, cold cloth on the inoculation spot to relieve pain, taking more fluids if getting a fever, and wearing light clothes to help feel more comfortable.

The report also mentioned more people begin experiencing side effects after taking the second shot because the first one only triggers the immune response while the second one boosts it.
