I have read that 5 doses can bring the efficacy up to as high as 80%.
So maybe the protection goes up 10% with each shot after the second? Or maybe one dose would only provide 40% protection? |

In general, inactivated vaccines are not as effective in producing immunity as are live vaccines.

Immunity appears to last for five to 10 years. Tdap vaccine is believed to be similar in effectiveness and duration of immunity as pediatric DTaP vaccines. |
| It is becoming clear that B. pertussis bacteria are capable of infecting and proliferating in a large proportion of vaccinated individuals. In one study, 33% of the exposed individuals receiving the highly effective five-component acellular pertussis vaccine had evidence of infection and 24% coughed for 21 days or more (19). In the same study, 82% of individuals receiving a licensed whole-cell vaccine had evidence of infection and 65% coughed for 21 days or more |
| Up to 95% of all polio infections are inapparent or asymptomatic. Estimates of the ratio of inapparent to paralytic illness vary from 50:1 to 1,000:1 (usually 200:1). |

I know people who've had varicella as adults who've been very sick from it. Hospitalized for a couple weeks in one case. That's certainly harder to deal with!

I would like some "protection" against Pertussis. It's the only disease that there's a vaccine for that actually worries me. My kid is about to enter a large public school next year.
<snip> I have given my daughter one vaccine, and that was Tetanus. We live in Maine. It's too possible that she'll be barefoot and get a puncture wound. And the treatment for that is --a tetanus shot. One that is worse (tocicity-wise) than the vaccine. So I got her the vaccine. I have to find out how the chickenpox thing works. At what point does chickenpox start becoming more dangerous? That's when I'd want to get her vaccinated, if she's not naturally immune. <snip> |

Have any of you heard anything about whooping cough (i.e. pertussis) in Savannah? I have been SO sick and can't quit coughing. It's been horrible, something I've never had before despite years of allergy and sinus problems. On my birthday I went to my doctor who did a chest X-ray and said that I did not have pneumonia, but he would treat me for asthma. He mentioned a nebulizer (I asked [one of the other mothers] and she said that's what [her son] used), but he never gave it to me. Instead he put me on tons of meds: Avelox (antibiotic), guaifenex (decongestant with expectorant), Prednisone (steroid), Hyphed (cough syrup with antihistamine, narcotic, decongestant), Albuterol ("rescue" inhaler) and Advair (preventative steroid inhaler). He warned me that the Advair has been known to cause death in some users, and that I should not use it more than the twice a day prescribed, as it is not a "rescue" inhaler like the Albuterol. That was Tuesday. I went to the ER this morning as I woke gasping for air and coughing and just couldn't take it anymore. Like my doctor, they took an X-ray, as well. The ER doctor said is it likely that my anxiety over my "asthma" has aggravated the condition. He gave me a Xanax and sent me home. It has not worked. I told him that at the moment (by the time we got there) I was "okay," but repeatedly have horrible coughing spells to the point of vomiting and complete loss of bladder control. (Yes, for my fortieth birthday I bought myself a nice pack of Poise pads. This is way worse than pregnancy.) And, yes, I am very stressed about it because I can't function, not to mention that I've frequently thrown-up my medication, which means it can't work, but I'm too scared to take another dose. And, I kept asking about this feeling in my throat and chest of breathing in fumes, like the newspaper, which does cause that reaction in me. (I even mentioned to the second nurse that I her perfume was really strong for me, and she said that she wasn’t wearing any; just soap and lotion.) So, I spent the day in bed. I just came downstairs and check my E-mail and such. I saw on the CNN main page that whooping cough is now becoming an epidemic in Winnetka, Illinois, the Chicago suburb of "Risky Business" fame. I've looked a little online to see about our area, but don't see anything, although there are reports of it occurring in North Carolina. [Since this post I've seen another report of a case in South Carolina.] Most reporting I’ve seen has been from past years. In any case, I found a web site which describes EXACTLY what I've been experiencing, right down the fact that it's so hard to diagnose, because often the patient doesn't have the spasms while in the office. But, all the other parts about the attacks ending with vomiting are just like what I'm having. And, my cough sounds just like the recordings I’ve listened to online. At this point, I would no longer be contagious, but still symptomatic. They could not do the simple swab test for me, but perhaps a blood test would show the antibodies. Actually, there isn't much to do for it, but everyone who wrote on the site about their experiences with their children or themselves (vaccine can wear off by my age) mentioned the relief they felt at knowing what they had and that it would eventually end. Also, they mentioned that bronchodilators, like I have, really do not work for whooping cough, but possibly the non-steroidal asthma medication Singulair would work. The steroids really raise my blood sugar, and my blood pressure is up again, as well. I spend my entire days coughing, vomiting and pissing myself. Gee, wonder why I might be anxious? I just can not take it, and while I do understand that anxiety can aggravate any medical condition, it just doesn’t explain all of my symptoms. Anyone heard anything about this in our area? It would be such a relief to know what’s wrong and to get the proper treatment if all that I’m doing will not work for what I have. I am just so exhausted... |

Hi, Imvishta! Welcome!
![]() Yeah, if you want to talk about pertussis in adults, you might want to start a new thread. It's an interesting subject, and deserves it's own discussion. ![]() |

If I'm not mistaken, polio still exists right here in the US - right?
