Finally, the last part of MMR vaccine; the R is for rubella vaccine and rubella vaccine is also a live virus vaccine. The strategy to prevent intrauterine infection in this country, to prevent congenital rubella syndrome, is to vaccinate everybody routinely. To do that you give the rubella vaccine, the live virus vaccine. The main reactions to be concerned about are an attenuated form of rubella. A mild rash, a low-grade fever, and in children sometimes you get some occipital or posterior auricular lymphadenopathy and arthralgia. In young women the rubella vaccine may be slightly more reactagenic, resulting in not only transient arthralgias but sometimes transient arthritis as well.

Precautions and contraindications are similar; pregnancy, immunocompromised – it might multiply more than you would want it to in that situation – and immune globulin will interfere with vaccine take. Excellent seroconversion is obtained with rubella vaccine. Again, a graph from the CDC shows a marked reduction in the cases of rubella in this country. It’s been quite successful.

So now we are going to move on from MMR vaccine and move on to H. flu type B vaccine. I haven’t talked much about the science behind a lot of these vaccines and that’s because that’s not important for test-taking purposes. However, with H. flu type B vaccine, that’s different. So I am going to spend a little bit talking about the science behind it. The important thing with H. flu type B in terms of immunity is immunity to the polysaccharides. However if you take the plain polysaccharide and you use that as a vaccine, it’s very weak. You get a very weak antibody response in infants and really don’t get a very good antibody response until 18-24 months of age. If you take this polysaccharide and you bind it to a protein, then it becomes a T-cell dependent immunogen. Canadian viagra for sale. It has enhanced immunogenicity, especially in infants, you get a better immune response and you get a booster response if you give repeated doses of vaccine or if you get exposure to H. flu type B. Because of this has been remarkably successful, as you’ll see. This is being applied to other vaccines and development of other vaccines, such as improved vaccine against pneumococcus, improved vaccine against meningococcus. And because of that, because you will see it in the future, this is the kind of thing, that basic science sort of thing, that actually may be tested because I think it is important to understand that this technology is improving vaccines.

So there are several different vaccines in general. It’s not important to know the main differences between them, but there are different manufacturers of the vaccine. The polysaccharide is linked to different protein carriers. Most of these have been used before so there is a lot of clinical experience with them, and that’s why they have been chosen. But all of them are very safe vaccines, very minor reactions, local reactions. Rarely you get a low-grade fever after vaccination with the routinely used HIB vaccines. Again, these have been remarkably successful. The conjugate vaccines were introduced in 1988 and then in 1990 they were recommended for infants. You can see invasive H. flu type B disease in this country more than a 95% reduction. This has been quite a success story.
We are going to move on to MMR vaccine. The first part of the M is measles vaccine. And measles vaccine is a live virus vaccine and you may get this live, attenuated, weakened form of the measles virus. It may multiply within the host and actually produce an attenuated case of measles, which you can see a week to 12 days after immunization, with a low grade fever and a mild rash. Seroconversion depends upon the age at which MMR vaccine is given. If you give it at a year of age you have excellent immunogenicity. Giving MMR vaccine at six months of age, you can see the seroconversion is only 50%. That’s because many children at six months of age will still have their passively acquired maternal measles antibody, if the mother is immune to measles and therefore this will interfere with vaccine take. It will inactivate the live vaccine so it won’t multiply and you won’t get a good immune response.

For measles vaccine, the precautions and contraindications are shown on this slide. Pregnancy; it’s a live vaccine, so theoretical concerns. Gelatin or a mycin allergy, this will be an anaphylactic allergy. That’s in the vaccine. Thrombocytopenia; measles-containing vaccine may cause a lowering of the platelet count, so in a patient with thrombocytopenia you could think about whether it’s worthwhile to vaccinate them against measles or not. Recent immune globulin will interfere with vaccine take. In general, immunocompromised subjects should not get MMR vaccine or measles-containing vaccine. And that’s because it may multiply more than you would want it to. However, HIV infected subjects may be give measles-containing vaccine, unless they are severely immunocompromised. Egg allergy; this is relatively new, over the past few years. Egg allergy in the past had been considered a contraindication of vaccination. No longer, as there is such a small amount of egg protein in the vaccine. Then the issue of the PPD. PPD may be performed on the day of vaccination or one month later. If you do it in between those times, the PPD may not be reliable.

The recommendations for measles vaccine; two doses after the first birthday separated by at least a month, so the general routine is to give the first dose at 12-15 months of age, the second dose, 4-6 years of age. And in an outbreak situation you can give an additional dose at six months of age but this doesn’t count for those two doses after a year of age because, again, the vaccine take is unreliable. This graph from the CDC just shows how successful we’ve been with vaccinating against measles. A marked decline and then here we had a little bit of outbreak of measles and this is where the second dose recommendation came in. It has really been very successful at controlling measles in this country.

Now we are going to move on to the second M in MMR, mumps vaccine. This is a slide from the CDC showing a child with parotid gland swelling due to mumps. Mumps does cause salivary gland swelling and also may cause complications – mostly in older individuals – may cause pancreatitis, meningitis, hearing loss as well as orchitis. Mumps vaccine is also a live virus vaccine. Reactions to mumps vaccine are rare. The precautions and complications are similar to what you’ve already heard for measles vaccine; pregnancy, immunocompromised, recent immune globulin will interfere with vaccine take, and the seroconversion is excellent with mumps vaccine. This graph from the CDC also illustrates a marked decline in mumps in this country with routine vaccine. So this has been quite successful.
I’m not going to talk much about whole cell DTP vaccine because it’s the old vaccine. Now what’s recommended and is preferred is to use the acellular vaccine because there are less reactions to it. The whole cell vaccine contains endotoxin and does have more reaction. Given in the same series as the acellular vaccine, has the same contraindications and precautions and similar efficacy. But it does have a lot of reactions, as shown in this table. This is a study by Cody and colleagues showing really the high rates of reaction to whole cell DTP vaccine; up to 50% local reactions, half the patients with fever and then systemic reactions, such as drowsiness, irritability, persistent crying. Again, a lot of these reactions due to endotoxin. Give the acellular pertussis component vaccine, you get less reaction and that’s why it’s preferred. But because it’s so reactagenic, in the past it’s been blamed for a lot of other things. Just to clear up some misconceptions; pertussis-containing vaccines do not cause sudden infant death syndrome. Pertussis-containing vaccines do not cause brain damage. There is no causal link between any pertussis component vaccine and brain damage. In the past some practitioners have given half doses of DTP vaccine in an attempt to prevent reaction. Half doses have not been well studied. The immunogenicity and efficacy of that is not well known and therefore you should not give half doses of vaccine. Give the regular dose.

Now polio vaccine; this is also one of these areas that is really in a state of flux, and a good portion of the polio discussion in the syllabus is about OPV, oral polio vaccine, live vaccine. And there are some changes in that regard that are coming up and therefore for Board review purposes, you have to realize it takes a while for these Board tests to catch up with what’s going on. So if you know the latest information, that’s fine. And if you know the old information, that’s fine too. You are not going to be dinked on that if it’s a transitional period and that’s where we are right now, in a transitional period. What you need to know is that the oral, live vaccine is a very good vaccine but it has a rare side effect. And that’s that the oral vaccine may mutate into a virulent form and cause vaccine-associated paralytic polio. This occurs rarely so the benefits of this vaccine outweigh the risks. However, in this day and age when we’ve done such an excellent job in eliminating polio from this country, the risks of vaccine are no longer acceptable. That’s why now we don’t recommend the oral vaccine and as of January 1st 2000, recommend that all four doses of polio vaccinations should be with the killed vaccine, the inactivated polio vaccine administered subcutaneously. The killed vaccine has no risk of reversion to the wild type, virulent strain. No risk of causing paralytic polio. The current schedule, however, – and in the syllabus and on this slide – until Y2K, is to give the first doses of IPV at two months and at four months of age. The second doses, personal choice; either OPV or IPV and I’m not going to go into the logistics of 6-18 months, 12-18 months and 4-6 years. Really what’s going to happen after January 1st is you should just give two months, four months, 6-18 months is the third dose of IPV and 4-6 years for the fourth dose of IPV. And then somebody will be up to date. Until then, the second two doses may be oral polio vaccine.

Precautions and contraindications are specific really for the oral polio component, which again is sort of out of date. But IPV should be used only for immunocompromised subjects or household contacts. The oral vaccine may multiply and can be transmitted person to person, and so should not be given if there is anybody immunocompromised, such as with HIV infection, in the household. In pregnancy there is a theoretical risk and so one should avoid vaccination if possible.
Again, tetanus toxoid comes in a variety of vaccine formulations and to prevent tetanus we really must pay attention to wound care. Cleaning the wound, making sure you debride any devitalized tissue and taking out any foreign body.

Finally, you put the D and T together with a pertussis component and you get DTaP vaccine, the acellular pertussis component, and that includes various components of Bordetella pertussis. Including possibly pertussis toxin, filamentous hemagglutinin, pertactin (pertucin?) fimbriae and a variety of combinations of these which we will get to. The main difference with DTaP vaccine and whole cell DTP vaccine is the decreased endotoxin content in the acellular formulation. This is given in a five day series, two for six months, 12-18 months and finally at 4-6 years of age. You do not give pertussis vaccines, at this point, at seven years of age and older. Only less than seven years of age. The efficacy of the DTaP vaccine is similar to DTP vaccine. About 80-95% and the reaction is lower rate to the common reactions compared to the DTP vaccine. Mostly because of the decreased endotoxin content. The DTaP vaccines are shown in this slide. These are all the FDA-approved vaccines. They are all different. They have different names, different manufacturers and different compositions; a variety of different antigens that are produced in different ways, they are in the vaccine in different quantities. For purposes of taking the test, these are all similar in terms of reactagenicity. There is no meaningful clinical differences between the reactagenicity and there are no meaningful differences between the efficacies of these vaccines and immunogenicities of these vaccines for test taking purposes. There is no difference in efficacy. So you really don’t have to spend too much time on the names and all that. But you do need to know that they are all different and they have different composition. The FDA has approved these for different doses. Really, from a practical standpoint, you can use any of these vaccines at any time. And these vaccines are interchangeable, although it is preferable for at least the first three doses to use the same vaccine, but not required.

The relative contraindications to pertussis vaccine are shown in this slide and this is different from an absolute contraindication. Pertussis, as you know, can be a very severe disease. So depending on a risk of a subject to pertussis and the complications that they could get from the disease, you need to weigh the risks and benefits. But prior vaccine reaction is a relative contraindication. That’s encephalopathy within seven days, a seizure within three days, persistent crying for three or more hours, collapse state or hypotonic hypo-responsive episode, fever greater than or equal to 40.5 C or an anaphylactic reaction. These are relative contraindications to further vaccination with any pertussis component vaccine. Anybody with a known or suspected progressive neurologic disorder or recent seizures. If you give the vaccine it may result in fever. Fever lowers the seizure threshold, this may induce the seizure and it may confuse the clinical picture. So anybody with those conditions or a known or suspected neurologic condition that predisposes to seizures or neurologic deterioration – the common example of that is tuberous sclerosis, where somebody may have tuberous sclerosis and may not show any signs or symptoms but you know that they are at risk for developing them – giving the vaccine may result in lowering the seizure threshold and then you are not sure. Was it the vaccine? Was it the disease? So you need to think about that.

In terms of specific vaccines, and we’ll talk about these when indicated, there are hyperimmune globulins with higher titer of antibody.These preparations are for hepatitis B, V-fig, tetanus immune globulin, rabies immune globulin and I hope we’ll have time to talk about RSV as well and the specific indications for that. Now we are going to talk about the specific vaccines, and also sometimes we will talk about the specific diseases if they haven’t been covered elsewhere in the course. This is a slide from the CDC showing tonsillar diphtheria and diphtheria is produced, a toxin-mediated disease, by Carinii bacterium diphtheria. This normally causes a respiratory disease. You can get cutaneous diphtheria also, and at other sites. The complication comes from the toxin which is a toxin that may cause myocarditis and other complications. Diphtheria vaccine is a toxoid vaccine, so it is taking the toxin and inactivating it. Therefore vaccination will not prevent colonization but it will prevent disease. There are two vaccine formulations. There is a big D, and you will see that with the DTaP, DTPM and DT vaccines, and then the little d, the TD vaccine and that’s to be used seven years of age and older. A smaller dose of the diphtheria toxoid and that’s all that’s needed for booster doses. When we talk about HIB vaccines you’ll notice some of them use, as a carrier, diphtheria toxoid. Diphtheria toxoid as a carrier in the HIB vaccine is not a primary immunogen and you can’t count that as vaccinating against diphtheria. You have to have the big D or the little d to count it as a diphtheria immunization.

Next we’ll talk about tetanus. This is a slide also from the CDC which shows a subject with opisthotonos, which is muscle spasm from tetanus. This is a neurotoxin and in pediatrics, one of the main problems with tetanus is neonatal tetanus. And this child has neonatal tetanus. This slide is from the WHO and this shows this child with this sardonic smile of neonatal tetanus. This is lockjaw in a baby and this occurs in areas of the world where the mothers are not immune to tetanus. So their children are born without the passively acquired tetanus antibodies. Commonly the umbilical stump, which is devitalized tissue, may get infected with Clostridium tetani which is an anaerobe, and then it produces the toxin and causes – it’s a neurotoxin – and causes lockjaw, muscle spasm. So to prevent term tetanus we have two tools available to us; active immunization and passive immunization. Tetanus toxoid, again toxin-mediated disease, purified component will prevent disease. Will not prevent colonization. Vaccine formulations include DTaP, DTP, DT and TD and tetanus immune globulin may also be used. That’s a hyperimmune globulin against tetanus, with high titers of tetanus antibodies. Then the issue comes up, when do you use the toxoid, when do you use tetanus immune globulin? The thing to remember about tetanus is that it is ubiquitous in the environment. It’s in dirt and it’s all around and because of that when a wound occurs, if the wound is contaminated and there is any sort of anaerobic tissue, devitalized tissue or foreign body, this may result in the organism colonizing the wound, producing the neurotoxin and then somebody coming down with tetanus. So if somebody has a wound that is significant and they’ve had less than three tetanus immunizations, then they need to be immunized and given tetanus immune globulin for a dirty wound only; three or more past tetanus immunizations, for dirty wounds immunized just more than five years since the last dose; and for clean wounds, immunized if more than ten years for the last dose. But in any case, if they’ve had three or more past tetanus immunizations you don’t need to give tetanus immune globulin because when you give tetanus toxoid there is a rapid memory response, an anamnestic response, that does result in adequate antibody to make sure that even if the organism is there that there will be enough antibody to fight off the toxin and prevent the disease.

The question arises; what’s a dirty wound, what’s a clean wound? All I can do is really give you an example. A patient is riding their motorcycle through a cow pasture, they crash into a rusty barbed wire fence, they have a mangled leg, devitalized tissue and they have some cow dung in the wound. That’s a dirty wound. A clean wound is, you are at home, you are slicing tomatoes and you make a nice clean slice in your finger and that’s a clean wound. You can wash it out, there is no foreign bodies in there, there is no real devitalized tissue, you can approximate the edges nicely. That will heal over nicely, and that’s a clean wound. So it’s a question of contamination and risk of disease from the wound.

So here we go to the heart of the matter, and this is the routine vaccination schedule for children in this country. And this is from the MMWR published by the CDC and this is approved by the American Academy of Pediatrics, the American Academy of Family Practice, and this is really just the general immunization schedule, that if you know this, you will know almost everything there is to know about immunization and for the next hour. So that’s all you have to memorize is this. For hepatitis B, in general, the shots – and we’ll talk about some of the recent changes in that. DTaP vaccine, five dose series; H. flu type B vaccine is three or four doses; for polio that has been a little bit changed but in general it’s four doses, and the first two are ITV. Rotavirus we will skip. MMR vaccine a two dose series; and varicella, one dose of varicella vaccine in general on the routine schedule. So this is all pretty straightforward and everything is pretty easy, right?

So the other part of this table is that there are just a few little footnotes and so this does tend to get a little bit complicated and that’s in regards to the individual vaccines. So we are going to talk about those coming up, the individual vaccines. But first I just want to remind you that some kids will come to you and they won’t be up to date on their immunizations. This is a table that’s in the syllabus and shows the catch-up immunization schedule. It just shows some general intervals. These are derived from the routine schedule and you can pretty much figure them out. This is something that you wouldn’t need to memorize but you do need to know when kids are under-immunized, which vaccines are indicated and figure out a schedule for them to get up to date on their immunizations.

Adolescent immunizations; there’s been a recent push to make the 11-12 year old visit a routine visit in the office for a variety of reasons, and including immunizations, to make sure that adolescents are caught up and up to date with some of the vaccines that may be different from when they were younger, such as make sure they get varicella vaccine. Make sure that they have two doses of MMR vaccine and that they are up to date on the hepatitis B vaccine series. Also you can give them a booster dose of tetanus at that time, and give other vaccines if indicated in special circumstances, such as hepatitis A vaccine, flu vaccine or pneumococcal vaccine.
Provigil information
We are going to talk briefly about passive immunization. I’ll talk about it more with hepatitis A. But in general, passive immunization is the administration of pre-formed antibody is effective preventing hepatitis A. Gamma globulin, you give that, and you can prevent that if given within 14 days of exposure. And measles within six days of exposure. Intravenous immune globulin, IV IG in general, also contains a wide variety of antibodies and you can use that in the same situation if somebody is getting that for another reason. This will also provide protection just like the IM version.
