You must take the vaccine of some potentially strong diseases like Hepatitis A, typhoid, yellow fever and rabies. Continue reading the blog post to know the best time to get vaccinated before travelling.
How vaccinations perform?
Vaccination performs with the introduction of little amount of weakened or inactive virus or bacteria. It also introduces inactivated toxins in the body through jab or oral application. Basically, poison or toxins generated by virus or bacteria are transferred to the body. It knows as immunisation to enhance your immune system.
As agent of vaccine is weak or inactive there is less chance of an infection. Instead, the immune system will start all over again as soon as the WBCs start performing well. As a result the body will make antibodies to fight off the infection from specific virus and bacteria.
The benefit is if similar virus or bacteria invades the body, the antibodies will wake up to protect your body from its bad affects. Sometimes, immune system persists for lifelong.
Which vaccinations a person need prior to travel abroad?
The necessary vaccination is depending on the destination! Planned activities and personal health are other attributes for determining the necessary vaccines. However, you have to maintain the timescale while planning the entire trip and tour.
On 7th-14th day after taking the jab the body starts developing protection to combat against the infection. But certain vaccines like Hepatitis B and Rabies need multiple doses spreading over multiple weeks for optimum immunity against them.
Yellow fever vaccination is mandatory when you plan to travel countries like South America and Africa. Interesting part is the yellow fever international certificate doesn’t valid till 10 days of administering the vaccine.
Many vaccinations come with lifelong protection meanwhile, some act as booster delivering protection just for few months to several years. Vaccine is essential every year for flu.
To travel outside UK, take advice from your GP at least 4 to 6 weeks of flying abroad. But seek early medical advice to deal with complex medical conditions.
Ensure to make concrete plan
Never rush to take the vaccination on last minutes as body can’t receive sufficient time for producing antibodies. So you are still at risk due to lack of protection and immunization.
Taking late vaccination refers to development of side-effects if any when you are travelling or on reaching the final destination. Proper recommendation is to take the vaccination 8 week before you take off. It is so; because the body need a couple of weeks more for making antibodies. Immunisation consumes some time to complete and many travellers need above 1 injection to travel and stay safe.
As per NaTHNaC if you are about travel outside UK then; opt for advice from GP before a month or so to travel safely. However, if you have complicated medical condition seek the advice as early as possible. It is worth visiting the GP around 8 weeks before as early immunisation is never harmful but surely late can.
If you are running out of time, still getting advice from the GP is beneficial! Last-minute vaccination is effective before the development of any disease along lengthy incubation period. On another flip, it is going to be worthwhile somehow even if you can’t get immediate protection for your first session of the trip.
GP will share some effective methods of preventive measures. Green Book refers to ‘Immunisation Against Infectious Disease’ that comprises latest information about vaccination procedures and vaccines in the UK.
What about side-effects of vaccination?
Travellers often end up with short-term and mild side effects like low-grade fever, headache and muscle pain (myalgia). You will experience these for the first initial 10 days of taking vaccination. Also they can react to several ingredients like gelatine and egg protein. So, you must inform about it to the nurse before taking the vaccine.
Rarely, severe allergic reaction can take place right after taking the jab. Anaphylactic reaction occurs as it contradicts in many people due to medical complexities. It is mostly seen in the aged persons about 60 years of age, HIV-infected persons, one having weak immune system and pregnant women.
Risks of not taking the vaccination
If you don’t take the jab on time then you are more likely to get an infection with the ability to transfer it too. Vaccination is not only to lessen the chance of infection but also a great shield to prevent the transmission of the infection and diseases on a wider prospect.
It increases the risk of public health due to lack of the vaccination. Also there is associated expenditure if any outbreak takes place.
Certain vaccines deliver a remarkably high protection level. But there are many with setback in their efficiencies like typhoid vaccine. In this case, additional care such as personal hygiene, water and food are also important at the same time.
