Your child will be given three doses of the meningococcal B (MenB) vaccine – one at two months, one at four months, and a booster dose at 12 months.
As with all vaccination appointments, aftercare is important – and according to the HSE, this is particularly the case after your child receives the MenB vaccine at their first two appointments.
Here’s what you need to know:
MenB vaccine and fever
The HSE says that when the MenB vaccine is given with the other vaccinations at your baby's two month (MenB + 6in1 + PCV + Rotavirus) and four month (MenB + 6in1 + Rotavirus) visits, there’s a higher risk they will develop a fever.
This is why the HSE advises you give your baby three doses of infant paracetamol straight after each appointment: one dose immediately, and two more doses later; dose two should be given 4-6 hours after dose one, and dose three given a further 4-6 hours after dose two. The paracetamol won’t stop your baby getting a fever, but it will help reduce it and clear it up quicker.
Always read the ingredients and the label before giving it to your child, and if unsure about anything, call or visit your GP for advice.
Checking your baby’s temperature
Keep a close eye on your baby’s temperature after their vaccination appointment, checking it regularly by placing a digital thermometer under their armpit. Anything between 36 and 36.8° C (96.8 and 98.24° F) is normal, while anything on or above 37.5°C is classed as a fever.
Always seek medical help if your baby is under three months and their temperature is higher than 37.5°C or if they are between three and six months and it's higher than 39°C (102.2°F) or if they are over six months and it's 40°C (104°F) or higher.
The 12 month visit
It’s not necessary to give your child paracetamol straight after the 12 month MenB appointment. However, it’s advised to check your child’s temperature regularly, and if they do develop a fever, you can follow the dosage as per the medicine’s instructions.
MenB and rotavirus
With the rotavirus vaccine, babies may get mild diarrhoea. This should clear up in a few days but again, if you’re worried, call or pop into your doctor for advice.
