Fetal safety - rules of thumb
• There is no evidence for risk and no
biologically plausible risk to a developing fetus
from vaccination of the mother using
– Sub unit vaccines
– Inactivated vaccines
– Whole-cell vaccines
• There are theoretical risks to the developing
fetus from vaccination of the mother using
live vaccines but no evidence for harm
• There are known risks from Smallpox vaccine
NZ Immunisation Handbook 2011 on
pertussis vaccination in pregnancy
- pg. 24-25
Tdap (Boostrix) vaccine
for pregnant women
• Now funded for pregnant women between 28 and
38 weeks gestation. Imms Benefit can be claimed
from 1st January 2013
• Supported by The NZ College of Midwives
• Must obtain informed consent and consider all
options- including not vaccinating, vaccinating
before, during and after pregnancy
• Main goal is to protect infants
How soon after Td can Tdap be given?
• NZ Immunisation Handbook 2006 stated 2 years6
• Canadian studies show no increase in adverse events for
those vaccinated 18-23 months after Td2-5
• The Immunisation Handbook 2011 states “when Tdap is
given to protect infants ……..from pertussis, a minimum
interval between doses does not apply” 1
• The ITF has just updated its advice to show that no
minimum interval is necessary at any age7,8

Influenza in pregnancy - risk to mother
• Excess hospital admissions in healthy
women
– Similar to non pregnant women with
comorbidities
• Excess hospital admissions in women with
co-morbidities
• Increases with gestation
• More vulnerable during pandemics
– 1918, 27% case fatality rate
– 1957, ½ deaths in young women were
pregnant
– 2009, 13% of all deaths from H1N1 were
pregnant

Influenza in pregnancy - risks to fetus
1. Infection and fever
– Associated with congenital abnormalities
2. Associated with increased risk of
cancer
– Neoplasms of lymphatic and
haematopoietic tissue 1957 Asian
influenza
– Neuroblastomas
3. Increased risk of general
complications

Protect yourself and your patients
• Annual influenza immunisation is strongly recommended for
all healthcare workers to protect vulnerable patients from the
threat of influenza illness.
• Many staff continue to work when sick, thereby exposing
influenza illness to patients and co- workers
• Annual influenza immunisation results in:
• improved patient safety
• improved employee safety and
• decreased healthcare expenditure

Influenza vaccine and narcolepsy?
• 2010 -Association found in Finland, Sweden & UK - increased
risk narcolepsy with Pandemrix H1N1 vaccine in 4-19 yr age
group.
• China found increased narcolepsy associated with H1N1
pandemic.
• Usual onset narcolepsy during adolescence/ young adult
• Strong genetic link
• All those in Finland had this genotype.
• Narcolepsy also associated with URTIs incl strep infections
• Incr risk of narcolepsy not found with other other vaccines
including other H1N1 vaccines
See IMAC fact sheet- Association between Pandemrix and onset of narcolepsy -1/2/2013
Febrile convulsions
• In 2010 there was an increase in reports of fever and febrile
convulsions in children vaccinated with Fluvax®
• A large NZ study with over 4000 infants and children was
undertaken in 2010 and 2011. It showed the risk of fever and
febrile convulsions following Fluvax® was significantly greater
than for other seasonal flu vaccines
• The Ministry of Health recommends that children under 9
years should be vaccinated with FLUARIX®
• FLUVAX® should not be given to any children with a history
of febrile convulsions
Meningococcal Vaccines
• New Men B vaccine approved in Europe (by Euro Commision
from 2 months age) and expected in UK and US soon
(4CMenB/ Bexsero®)
– Recombinant proteins x 3 + OMP from MeNZB
– Adsorbed onto aluminium
• Recommendations re Meningococcal vaccines for hostel
dwellers (see IH 2011 pg 300)
