Whooping Cough (Pertussis)

Whooping cough causes serious long bursts of continuous coughing and choking, which makes it difficult to breathe. This sometimes causes a ‘whoop’ noise where there is an attempt to gasp for breath between coughing.You can hear an example of what whooping cough can sound link by clicking the link here

Symptoms in adults and children may include:

• Cold like symptoms (runny nose, red and watery eyes, sore throat and slightly raised temperature).
• Intense coughing bouts lasting a few minutes at a time (usually starting a week from onset of cold like symptoms).
• Coughing up thick mucus which may be followed by vomiting.
• Gasping for breath between coughing causing a ‘whoop’ noise (although not everyone experiences this).
• Slight bleeding to the eyes or under skin from intense coughing.
• Turning blue (babies and young children) from difficulty breathing.

In new born (and very young) babies, the cough may not be particularly noticeable but there may be brief periods where they stop breathing.

The coughing bouts will start to become less severe and less frequent over time. The infection usually lasts for around 2-3 months and the severity of the infection is different from person to person; it is usually serious.

Whooping cough can affect people of any age if they are to come in close contact with someone else who has the whooping cough infection. People are contagious from about 6 days after being infected (usually as cold-like symptoms are starting) until around 3 weeks after the coughing bouts start.

Those at risk of catching whooping cough:

• Babies and young children (increased risk).
• Older children and adults (usually less serious).
• People who have had whooping cough before (a previous infection does not provide immunity against the disease).
• People vaccinated against whooping cough as a child (protection from the childhood vaccine usually wears off within a few years).
• Certain groups are more vulnerable to infection in particular new born babies.

People of any age can catch whooping cough but is most dangerous for new born babies. This is because babies have poorly developed immune systems and it is harder for them to fight off infections.

Whooping cough can cause:

• Temporary pauses in breathing and difficulty breathing.
• Weight loss due to excessive vomiting.
• Pneumonia
• Seizures or brain damage.
• Encephalitis (swelling of the brain).
• Hospitalisation
• Death

There is currently a big increase in the number of people catching whooping cough and the number of babies getting severely unwell and even dying from whooping cough is unfortunately increasing. It is known that the babies that do sadly die from whooping cough are often those that are infected before they were old enough to receive their own vaccination. This is why the vaccination during pregnancy is so important.

To prevent further deaths and serious harm to babies, since 2012 it has been recommended that all pregnant women are offered the whooping cough vaccine.

The whooping cough vaccine is an injection given to pregnant women to protect their new-born babies from the disease, as well as themselves. It is a 4 in 1 vaccine, providing protection against diphtheria, tetanus and polio in addition to whooping cough. A single dose whooping cough vaccine does not yet exist.

It is not a live vaccine, it has been inactivated (killed) and therefore you cannot catch whooping cough or any of the other diseases from having the vaccine.

Over the two weeks after receiving a whooping cough vaccination, your body begins creating antibodies that protect you against infection should you come in contact with someone carrying the disease. These antibodies also pass through the placenta to your baby who will remain protected until they receive their whooping cough vaccine at around 8 weeks of age.

You still need to have a whooping cough vaccine even if you received one yourself as a child or if you have already had one as an adult in a previous pregnancy because protection only lasts for a limited time.

The whooping cough vaccine is safe to have from 16 weeks in pregnancy. It is available all year round and it is recommended that pregnant women have the vaccine before 32 weeks to ensure maximum protection to their babies.

You may be able to have this vaccination at the same time as your 20 week scan if your maternity unit is providing this service. Please speak with your midwife to see what services are available to you.

To be effective and to provide each baby with the same level of protection, it is recommended that you have a whooping cough vaccine in each pregnancy. This is because antibodies do not stay at high levels in the blood for very long.

Yes, both directly and indirectly.

Studies show that the whooping cough vaccine is around 92% effective at preventing the disease in new-born babies if given between 16-32 weeks. This means that if 100 babies from vaccinated mothers were exposed to the whooping cough vaccine, only 8 of these babies would be likely catch the illness. The numbers of deaths due to whooping cough in young babies has dropped significantly since the introduction of the maternal vaccine in 2012.

Being vaccinated against whooping cough also means that as a mother you are less likely to catch it yourself and therefore are less likely to pass it on to your baby once they are born.

Since being routinely introduced in 2012, data from 20,000 women who have received the vaccine during pregnancy show that there is no evidence of an increase in the risk of congenital abnormalities or stillbirths.

Healthcare professionals recommend vaccinations based on evidence that shows a strong benefit to very little or no known risk.

There is good, strong evidence that the vaccine works extremely well. Studies show that babies born to vaccinated mothers are highly protected. The vaccine is around 92% effective – meaning out of 100 babies born to vaccinated mothers, only 8 babies would catch pertussis if exposed to the bacteria.

The vaccine in pregnancy protects your baby for the first few weeks of their life (when they are at highest risk of getting severely unwell from whooping cough). However, babies remain at high risk of severe whooping cough for the 1st year of life; it is really important that they remain protected by having their infant vaccines (at 8 weeks, 12 weeks and 16 weeks of age). So make sure that these are not delayed.

And try to avoid contact with anyone you suspect may have whooping cough while you are pregnant and also once your baby is born.
