Introduction

Dengue fever is a viral infection transmitted by mosquitoes, primarily found in tropical and subtropical regions. As travel becomes more accessible, the risk of contracting dengue fever increases for those visiting endemic areas. With the introduction of the dengue fever vaccine, many potential travellers are left wondering about its safety and efficacy. This article aims to address the concerns regarding the risks associated with the dengue fever vaccine, particularly for those in Bracknell, Berkshire, who may be planning their next adventure.

Understanding Dengue Fever

What is Dengue Fever?

Dengue fever is caused by the dengue virus, which is spread through the bite of infected Aedes mosquitoes, particularly Aedes aegypti. Symptoms can range from mild to severe and may include high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. In some cases, dengue can progress to severe dengue, which can be life-threatening.

The Importance of Vaccination

Vaccination is a critical tool in preventing dengue fever, especially for those travelling to areas where the disease is endemic. The dengue vaccine, known as Dengvaxia, is designed to protect against the four serotypes of the dengue virus. It is particularly recommended for individuals who have previously been infected with dengue, as it can reduce the risk of severe dengue upon subsequent infections.

The Dengue Vaccine: Safety and Efficacy

Overview of the Dengue Vaccine

Dengvaxia is the first vaccine approved for the prevention of dengue fever. It has been shown to be effective in reducing the incidence of dengue fever in individuals aged 9 to 45 years who have had a previous dengue infection. The vaccine is administered in three doses over a 12-month period.

Common Side Effects

Like any vaccine, the dengue vaccine can cause side effects. Common side effects include pain at the injection site, headache, muscle pain, and fever. These side effects are typically mild and resolve within a few days. However, it is essential for individuals considering the vaccine to be aware of these potential reactions.

Serious Risks and Concerns

While the dengue vaccine is generally safe, there are concerns regarding its use in individuals who have never been infected with dengue. Studies have shown that vaccination in these individuals may increase the risk of severe dengue if they contract the virus later. This has led to recommendations that the vaccine should only be given to those with a confirmed history of dengue infection.

Who Should Get Vaccinated?

Recommendations for Travellers

For residents of Bracknell planning to travel to dengue-endemic areas, it is crucial to consult with a healthcare professional. The dengue vaccine is recommended for individuals aged 9 to 45 years who have had a previous dengue infection. If you are unsure about your dengue history, a blood test can confirm past infections.

Special Considerations

Certain groups, such as pregnant women, individuals with weakened immune systems, and those with a history of severe allergic reactions, should discuss the risks and benefits of vaccination with their healthcare provider. It is essential to weigh the potential risks against the likelihood of exposure to dengue fever in your travel plans.

Alternatives to Vaccination

Preventative Measures

In addition to vaccination, there are several preventative measures that travellers can take to reduce their risk of contracting dengue fever. These include:

• Using insect repellent: Apply a repellent containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin.

• Wearing protective clothing: Long sleeves and trousers can help protect against mosquito bites.

• Staying in screened or air-conditioned accommodations: This can reduce the likelihood of mosquito exposure.

• Eliminating standing water: Mosquitoes breed in stagnant water, so it is essential to remove any potential breeding sites around your accommodation.
