Yellow fever - Vaccination


Prevention
-
Insect bites and stings





There are some simple precautions you can take to reduce your risk of being bitten or stung by insects.
It is particularly important to follow this advice if you have had a bad reaction to an insect bite or sting in the past or you are travelling to an area where there is a risk of picking up a serious illness.

Typhoid fever - Vaccination

Vaccination-Typhoid fever




Vaccination against typhoid fever is recommended if you're travelling to parts of the world where the condition is common.

High-risk areas

Typhoid is found throughout the world, but it's more likely to occur in areas where there's poor sanitation and hygiene. 
High-risk areas include:
  • the Indian subcontinent
  • Africa
  • south and southeast Asia
  • South America
Vaccination is strongly recommended if you're going to be staying or working with local people, or if you're going to be staying for prolonged periods in areas where sanitation and food hygiene are likely to be poor.
In the UK, most people who get typhoid fever develop it while visiting India, Pakistan or Bangladesh. It's therefore particularly important that you're vaccinated if you're visiting these countries.
Vaccination against typhoid fever is usually free on the NHS from GP surgeries. Private travel clinics also offer the vaccine for about £30.

Choosing a typhoid vaccine

In the UK, the 2 main vaccines available to prevent typhoid fever are:
  • Vi vaccine – given as a single injection
  • Ty21a vaccine – given as 3 capsules to take on alternate days
Combined typhoid and hepatitis A injections are also available for people aged 15 or over. Protection against hepatitis A lasts 1 year and protection against typhoid lasts 3 years.
The vaccines work by stimulating your body to create antibodies (infection-fighting proteins) that prevent you getting ill if you become infected with the typhoid bacteria.
But neither typhoid vaccine is 100% effective, so you should always take precautions when eating food and drinking water abroad.
As the Ty21a vaccine contains a live sample of Salmonella typhi bacteria, it isn't suitable for people with a weakened immune system – for example, people receiving certain types of treatment, such as chemotherapy. 
It also isn't usually recommended for children under 6, whereas children can have the Vi vaccine from 2 years of age.
It's unclear whether the Vi and Ty21a vaccines present a risk to pregnant or breastfeeding women. But vaccination should be considered if there's a significant risk of getting typhoid.
The typhoid vaccine should ideally be given at least 1 month before you travel, although if necessary it can be given closer to your travel date.
Booster vaccinations are recommended every 3 years if you continue to be at risk of infection with typhoid bacteria.

Side effects of typhoid fever vaccine

After having the typhoid fever vaccine, some people have temporary soreness, redness, swelling or hardness at the injection site.
About 1 in every 100 people have a high temperature (fever) of 38C (100.4F) or above.
Less common side effects include:
Severe reactions are rare for both typhoid vaccines.

Advice for travellers

Whether you have been vaccinated against typhoid or not, it's important to take basic precautions when travelling in countries where typhoid fever is present.
For example:
  • only drink bottled water from a bottle that was properly sealed, or water that's been recently boiled 
  • avoid ice cream and don't have ice in your drinks
  • avoid uncooked fruit and vegetables, unless you have washed them in safe water or peeled them yourself
  • avoid shellfish, seafood and salads

Rabies - Vaccination

Vaccination-Rabies




A vaccine is available to help protect people at risk of being exposed to rabies.
But even if you've been vaccinated, you should get urgent medical help if you're bitten or scratched by an animal that may have had rabies.

Who should have the rabies vaccine

People going travelling

You should consider getting vaccinated against rabies if you're travelling to an area of the world where rabies is commonand:
  • you plan to stay for a month or more, or there's unlikely to be quick access to appropriate medical care
  • you plan to do activities that could put you at increased risk of exposure to animals with rabies, such as running or cycling
It takes up to 4 weeks to complete the vaccine course, so you ideally need to start it at least a month before you plan to leave.
Pregnant women are advised to have the rabies vaccine if the risk of exposure to rabies is thought to be high and there's limited access to medical care.

People at risk through their work

Vaccination is also recommended for anyone at risk of being exposed to rabies through their job (paid or voluntary), such as:
  • people who regularly handle bats
  • people who handle imported animals, such as workers at animal quarantine centres
  • laboratory workers who handle rabies samples
If you think this applies to you, speak to your employer or occupational health provider. If you regularly handle bats in a voluntary role, speak to your GP about rabies vaccine.

Where to get the rabies vaccine

You may be able to get the rabies vaccination at your local GP surgery, but you may need to pay for it.
Alternatively, you can pay for the vaccine at a private travel vaccination clinic.

Will I have to pay for the rabies vaccine?

You'll usually have to pay for the rabies vaccine if you need it for protection while travelling.
The vaccine course involves 3 doses. Each dose usually costs around £40 to £60, with a full course typically costing around £120 to £180.
If you need the vaccine because there's a risk you could be exposed to the infection through your job, your employer should be able to provide it for you free of charge. Ask your employer or occupational health provider about this.
If you regularly handle bats in a voluntary role, you should speak to your GP to see if you are eligible for free vaccine.

How the rabies vaccine is given

The rabies vaccine is given as injections into your upper arm.
You'll need 3 doses of the vaccine, usually over a period of 28 days.
If you're planning to travel to an area where rabies is found, you should complete the full course of 3 doses before you leave.

Booster doses

If you've been vaccinated against rabies before but you continue to be at risk – for example, through your job – you may need further "booster" doses to ensure you stay protected.
Speak to your employer or occupational health provider about the booster doses you might need.
For travellers, 1 booster dose may be considered if you were vaccinated more than a year ago and you're travelling to a high-risk area again.

Side effects of the rabies vaccine

After having the rabies vaccine, some people have temporary soreness, redness and swelling at the injection site for 24 to 48 hours.
In rare cases, some people also experience:
  • a mild high temperature (fever)
  • a headache
  • muscle aches
  • vomiting
  • a rash
The vaccines used in the UK contain an inactive (dead) form of the rabies virus, so you cannot catch rabies by being vaccinated.

Meningitis - Vaccination

Vaccination-Meningitis




Meningitis can be caused by a number of different infections, so several vaccinations offer some protection against it.
Children should receive most of these as part of the NHS vaccination schedule.
Speak to your GP if you're not sure whether your or your child's vaccinations are up-to-date.

Meningitis B vaccine

The meningitis B vaccine is a new vaccine that offers protection against meningococcal group B bacteria, which are a common cause of meningitis in young children in the UK.
The vaccine is recommended for babies aged 8 weeks, followed by a second dose at 16 weeks and a booster at 1 year.

6-in-1 vaccine

The 6-in-1 vaccine, also known as the DTaP/IPV/Hib/Hep B vaccine, offers protection against diphtheria, tetanus, whooping cough, hepatitis B, polio and Haemophilus influenzae type b (Hib).
Hib are a type of bacteria that can cause meningitis.
The vaccine is given on 3 separate occasions, when babies are 8, 12 and 16 weeks old.

Pneumococcal vaccine

The pneumococcal vaccine offers protection against serious infections caused by pneumococcal bacteria, including meningitis.
Babies receive the pneumococcal vaccine as 3 separate injections, at 8 weeks, 16 weeks and 1 year old.

Hib/Men C vaccine

The meningitis C vaccine offers protection against a type of bacteria called meningococcal group C bacteria, which can cause meningitis.
Babies are offered a combined Hib/Men C vaccine at 1 year of age.
Teenagers and first-time university students are also offered vaccination against meningococcal group C bacteria as part of the combined meningitis ACWY vaccine.

MMR vaccine

The MMR vaccine offers protection against measles, mumpsand rubella. Meningitis can sometimes occur as a complication of these infections.
The vaccine is usually given to babies at 1 year of age. They'll then have a second dose when they're 3 years and 4 months old.

Meningitis ACWY vaccine

The meningitis ACWY vaccines offers protection against 4 types of bacteria that can cause meningitis: meningococcal groups A, C, W and Y.
Young teenagers, sixth formers and "fresher" students going to university for the first time are advised to have the vaccination.

Hepatitis A - Vaccination

Vaccination-Hepatitis A





Vaccination against hepatitis A is not routinely offered in the UK because the risk of infection is low for most people. It's only recommended for people at high risk.

Who should have the hepatitis A vaccine

People usually advised to have the hepatitis A vaccine include:
  • close contacts of someone with hepatitis A
  • people planning to travel to or live in parts of the world where hepatitis A is widespread, particularly if sanitation and food hygiene are expected to be poor
  • people with any type of long-term liver disease
  • men who have sex with other men
  • people who inject illegal drugs
  • people who may be exposed to hepatitis A through their job – this includes sewage workers, people who work for organisations where levels of personal hygiene may be poor, such as a homeless shelter, and people working with monkeys, apes and gorillas
Contact your GP surgery if you think you should have the hepatitis A vaccine or you're not sure whether you need it.
