Understanding Common Side Effects of Shingles Vaccine Shingrix: Dizziness and Fever Revisited

Many wonder if the dizziness and fever experienced after receiving the Shingrix vaccine are normal reactions. This article explores the common side effects and what to expect post-vaccination.

Exploring the Prescribing Information

Before taking the Shingrix vaccine, it's crucial to familiarize oneself with the Prescribing Information (PI). However, it's often written in a professional language that can be daunting for the average individual, even for a pharmacist. Instead, most pharmacists provide a simpler, layperson-friendly summary.

Common Side Effects of Shingrix

The Shingrix vaccine is known to cause pain and swelling at the injection site, which can range from mild to moderate for about 30% of recipients. For many, the discomfort is severe enough to prevent participation in their daily activities like attending the gym. Fever and generalized malaise are also common post-vaccination symptoms. These are often a sign that the body's immune system is responding appropriately to the vaccine, identifying and reacting to the antigens.

Second Dose of Shingrix: A Range of Reactions

Many report more pronounced symptoms after the second dose of Shingrix. In the case of another individual, symptoms like fatigue (described as "feeling draggy") only lasted for around one and a half days. Despite these side effects, it's important to remember that the vaccine is designed to protect against a serious disease with potentially severe complications. Similar to any drug, there's a risk of side effects, which, although uncomfortable, are generally manageable and brief.

Closer Considerations

It's also important to understand that while the vaccine is highly effective, it is not 100% guaranteed to prevent all cases of shingles. The vaccine works to boost the immune system, which might already have some residual memory cells from the chicken pox virus. However, this doesn't mean everyone will have the same reaction. Some individuals might have a more severe reaction, which should be reported to a healthcare provider.

Important Disclaimers

One additional point of caution is the ongoing concern of breakthrough infections in vaccinated individuals. While rare, it's important to follow public health guidelines and remain vigilant, including getting tested if symptoms arise, especially for those who may have contracted the virus.

Regarding the smoking and respiratory health connection, it's important to note that smoking cigarettes or any form of tobacco can negatively impact lung capacity and increase the risk of respiratory diseases. This is particularly relevant in the context of diseases like COVID-19, which primarily affects the lungs. Smokers might be at a higher risk of developing severe outcomes and mortality due to respiratory infections, including COVID-19.

Conclusion and Further Reading

While some people may experience uncomfortable side effects after receiving the Shingrix vaccine, such as dizziness and fever, these are generally considered common and manageable. However, if these symptoms persist or become severe, it's crucial to consult a healthcare professional.
