Are We Sending AClear Message?

Vaccine Organizationin Canada

Local Authorities Tend to beQuite Dogmatic

Sophisticated Parents Often Confronted by Mixed Messages

Aside from program issues, therereally aren’t many cogent arguments against some flexibility … • age at MMR or varicella (any vaccine) • number of doses - menC - HBV - HPV

Sloth, poor parenting and procrastinationmeant our 3 kids got MMR at 15, 16 and 18 months of age …

Needles are Not a Huge Factor … but they ARE a Factor for Some

Why are we Still Using this Medieval Tool?

• first used in Roman times • mostly for sucking stuff out (Egypt/Iraq) • 1844 - first subcutaneous injection with a hollow needle (Ireland) • 1853 - first ‘hypodermic’ syringe

for medical purposes (UK)

allposters.com

There are many reasons to target development of NEEDLE-FREEvaccines: • taking the needle out of the equation • HCW safety • keeping ‘sharps’ out of environment • probably better immune responses

The ‘It’s Good Enough’Attitude is Probably NOT Good Enough

For Vaccines

Are we all too ‘invested’ in vaccine programs to respond appropriately

to problems?

alaska-in-pictures.com

Our Defensive Reflexes are Well-Developed

Answer the following questions.YES or NO answers only:

YES NO

Measles vaccine uses a live (weakened) virus

This virus can persist for years

This vaccine can kill some children

This vaccine is probably as dangerous as OPV that we no longer use because of its risks

Major vaccine makers working on a safer measles vaccine?

gettyimages.com

OK - I can see see a few hands raised to speak… but we’re not done yet

More questions - same rules:YES NO

Adverse events can happen years post-vaccine

Vaccines licensed only after years of surveillance

Immunity after natural infection often for life

Immunity after vaccination is also lifelong

Some vaccines contaminated with animal viruses

Vaccine makers have monopolies on some products that are worth many millions of dollars

Governments & academics can independently confirm company claims for all vaccines

These questions are obviously unfair and biased …

However - each ‘yes’ or ‘no’ has some truth in it.

Each is a building block of the anti-vaccine argument

We’ve made safer vaccines for: • rabies • pertussis • polio • even smallpox

upmc-biosecurity.org

• Can’t neglect old vaccines chasing new targets • As we approach eradication of measles … will the current vaccine be safe enough?

• Insist that products in Canada can be studied independently

• Work harder to understand how vaccines work and how adverse events occur

• Support programs to compensate those who are truly harmed
