The deployment of vaccines against COVID-19 has been an unmitigated success, hastening the end of restrictions in the UK and giving people back their crucial liberties. The data continues to attest to the benefits of getting vaccinated; while the caseload is still high, the NHS is not feeling the effects. However, there are serious side effects after receiving the coronavirus jabs, although they are an extremely rare occurrence and the risks posed by catching coronavirus far outweigh the risks of getting vaccinated.
The potential side effects have been tallied as the Covid vaccines made their way into different populations.
According to Pfizer’s official website, there are a number of “feelings” in the chest following vaccination with the Pfizer-BioNTech jab that require seeking “medical attention right away”.
These feelings include:
Having a fast-beating heart
According to Pfizer, chest pain and shortness of breath should also promote medical help.
As the Pharmaceutical giant notes, these may not be all the possible side effects of the Pfizer-BioNTech COVID-19 Vaccine.
However, “serious and unexpected side effects may occur”.
The case for getting vaccinated
The chances of getting serious side effects post-vaccination are vanishingly small.
It is important to note that COVID-19 vaccines have to go through several stages of clinical trials before they can be approved for use.

Clinical trials are where a vaccine or medicine is tested on volunteers to make sure it works and is safe.
All vaccines used in the UK must be approved by the independent Medicines and Healthcare products Regulatory Agency (MHRA).
The MHRA makes sure the vaccines meet strict international standards for safety, quality and effectiveness.
Once a vaccine is approved, it’s closely monitored to continue to make sure it is safe and effective.
What’s more, catching COVID-19 if you’re not vaccinated can pose grave health risks both in the short-term and long-term.
In the near-term, there is the risk of hospitalisation and death, but the longer-term effects could be the result of ‘long Covid’.
Many people feel better in a few days or weeks and most will make a full recovery within 12 weeks. But for some people, symptoms can last longer.
According to the NHS, the chances of having long-term symptoms does not seem to be linked to how ill you are when you first get COVID-19.
“People who had mild symptoms at first can still have long-term problems,” explains the NHS.
Common long COVID symptoms include:
- Extreme tiredness (fatigue)
- Shortness of breath
- Chest pain or tightness
- Problems with memory and concentration (“brain fog”).
The long-term effects continue to be monitored and effective treatments are actively being explored.
