While with a group of friends, the subject came up that grandparents (and other family members) are being told they must get a Tdap vaccine before meeting the new baby in the family to protect baby from pertussis/whooping cough. It's an issue that has caused conflicts within some families.
You might recall seeing the rather frightening GlaxoSmithKline (GSK) "big bad cough" campaign, targeting grandparents, where Grandma morphs into a big bad wolf ready to cough on the infant and infect him or her with pertussis. In case you haven't seen it, it's included in the video below.
It is true that pertussis (whooping cough) is especially dangerous for a young baby; but the fact is -- and it's backed by science -- the adult getting the pertussis vaccine just might put baby at an even higher risk; because even though the vaccine recipient will not exhibit symptoms -- which would probably have kept him from visiting baby in the first place -- he or she can unknowingly have and transmit the illness to others, including the new baby.
Del Bigtree (Vaxxed, ICAN, HighWire) gives a good explanation -- complete with props -- in the video below. Take time to watch.

So, if you or someone you know has been told they must get a pertussis vaccine to protect the new baby, be sure to read the information I've included below and share it with them...and their doctors.
Acellular pertussis vaccines protect against disease but fail to prevent infection and transmission in a nonhuman primate model
In this study, we show nonhuman primates vaccinated with aP were protected from severe symptoms but not infection and readily transmitted Bordetella pertussis to contacts...and a cross-sectional study showed that postpartum aP vaccination of mothers did not reduce pertussis illness in young infants. These data suggest that cocooning is unlikely to be an effective strategy to reduce the burden of pertussis in infants. Read full study.
Resurgence of Whooping Cough May Owe to Vaccine’s Inability to Prevent Infections
The startling global resurgence of pertussis, or whooping cough, in recent years can largely be attributed to the immunological failures of acellular vaccines, School of Public Health researchers argue in a new journal article...“This disease is back because we didn’t really understand how our immune defenses against whooping cough worked, and did not understand how the vaccines needed to work to prevent it,” said Christopher J. Gill, associate professor of global health and lead author of the article. “Instead we layered assumptions upon assumptions, and now find ourselves in the uncomfortable position of admitting that we may made some crucial errors. This is definitely not where we thought we’d be in 2017.” Read more.
The relationship between mucosal immunity, nasopharyngeal carriage, asymptomatic transmission and the resurgence of Bordetella pertussis
The incidence of whooping cough in the US has been rising slowly since the 1970s, but the pace of this has accelerated sharply since acellular pertussis vaccines replaced the earlier whole cell vaccines in the late 1990s. A similar trend occurred in many other countries, including the UK, Canada, Australia, Ireland, and Spain, following the switch to acellular vaccines. The key question is why. Two leading theories (short duration of protective immunologic persistence and evolutionary shifts in the pathogen to evade the vaccine) explain some but not all of these shifts, suggesting that other factors may also be important.

Why is Whooping Cough on the Rise?
Evidence points to limitations of the current pertussis vaccines
Whooping Cough Outbreaks Continue Nationwide Due to Failed Pertussis Vaccine
Once blamed on unvaccinated children, few today deny the fact that fully vaccinated children are spreading whooping cough as outbreaks continue across the U.S...The pertussis vaccine is supposed to protect against whooping cough, and even though health officials now acknowledge that the vaccine is not effective, it is still required.

Pertussis: Vaccine Failure, Not Failure to Vaccinate
These studies show that the Pertussis (whooping cough) vaccine has now failed. Studies show that by five years after completion of the DTaP series, children were up to 15 times more likely to acquire pertussis compared to the first year after the series. Read more.
*The pertussis vaccine is only available in combination with tetanus and diphtheria. Before getting any vaccine, be sure to weigh the risks and the benefits. Read the actual vaccine package insert for a list of ingredients, warnings, contraindications, adverse effects, etc., and read the
