A wide range of side effects have been recorded in people who have received coronavirus vaccinations.

It’s vital to understand that vaccine reactions are to be expected; the immune system is producing an immunological response that will prepare it to fight COVID-19.

Despite this, the list of adverse effects recorded by reputable health organisations has provided vital information into how vaccines affect the body.

To provide optimal protection, the current vaccinations approved in the United States by Pfizer/BioNTech and Moderna require a two-shot regimen, and specialists on J&J vaccines have now decided to double the doses.

According to available research, negative effects can vary depending on the dose.

The Centers for Disease Control and Prevention (CDC) studied the effects of the vaccine on volunteers from different age groups.

According to the CDC, the “frequency and severity of systemic adverse events was higher after dose two than dose one”.

The data is based on vaccine recipients asked to complete diaries of their symptoms during the seven days after vaccination.

“Vomiting and diarrhoea were exceptions, and similar between vaccine and placebo groups and regardless of dose,” notes the CDC.

For both age groups, fatigue, headache and new or worsened muscle pain were most common, the data showed.

Overall, the average onset of side effects in the vaccine group in general was one to two days after either dose and lasted a median duration of one day, reports the CDC.

Other common side effects include:

• Feeling or being sick
• A sore arm from the injection
• Feeling tired.
