Immunized Measles Baby
2 different vaccines: There are 2 brands available: Rotarix (2 dose schedule) and RotaTeq (3 dose schedule) both are started at baby's 2 month visit though can be given as early as six weeks. A second dose is given 6-8 weeks later (can receive as early as 4 weeks after) and third dose (depending on which vaccine) no later than 32 weeks of age. This is given by mouth and not as a shot. ...Read more
Mostly: Although vaccines are safe and effective, there is an occasional peron whose immune system does not respond well to the recommended series. Thus they are not immune. If needed, blood tests can measure this. Still worth immunizing to maximize protection. ...Read more
Prevnar (pneumococcal vaccine) 13 vaccine has diphtheria proteins in it. Does Prevnar (pneumococcal vaccine) 13 vaccine protect against pneumococcus and diphtheria? Thank-you!
No: The diphtheria proteins used for PCV-13 (Prevnar) are not antigenic for diphtheria. That means they are not recognized by the body to produce an immune response. They just help carry the pneumococcal proteins into the appropriate cells to create the immune response for the pneumococcal bacteria. ...Read more
If vaccination protects children from diseases, why can an unvaccinated child infect a vaccinated child?
Vaccines seldom 100%: The protection provided by vaccines can approach 100% in some cases but not all. Infected kids spread their diseases to infants that are too young to be vaccinated, those that have not completed a full vaccine series or those whose immune system fails to have a full benefit from the vaccine.A measles outbreak in houston was traced to air travelers entering from abroad, 1/3 vaccinated, 2/3 not. ...Read more
Possibly: Introduced in the late 70's in japan, the current CP vaccine was not adopted in the us until the 90's. There are good data that one dose removes the risk of death with cp, but likely only 85% get protective immunity from 1 dose, with that improving to >95% after 2 doses given at least a month apart. Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good. ...Read moreSee 1 more doctor answer
Rabies vaccine: Rabies vaccine is under class C, that means that animal studies revealed a harmful or teratogenic effects on the fetus or there is no controlled studies on pregnant women, you need to weigh your options, risk vs benefit, if you were exposed & at risk for contracting rabies you have no choice but to take the vaccine with close F/U with your obstitrician. Wishing you & baby good luck. ...Read more
Yes: Rsv prophylaxis only protects against pneumonia. With the new drug motavizumab the lokelihood fir upper resp tract infection is lower. Keep in mind that there is no immunity after the prophylaxis. Its an antibody. Not a vaccine. The concentration drops after administration and needs to be repeated. ...Read more
YES!: The hib vaccine protects babies and infants against a type of bacteria which can cause meningitis and death. When i started my medical training, it was a fairly common, and serious, infection. Due to the success of the vaccine, it is now uncommon. H1n1 is a part of the influenza vaccine which keeps patients from getting the seasonal flu and should be given to all people over 6 months of age. ...Read more
Can be elevated: Vaccination like the illness it's designed to prevent (or reduce in severity) may cause fever as a normal physiologic response. In the animal kingdom, fever helps fight infection. Consider experiments where cold blooded animals given a bacteremia survive better when exposed to heat as opposed to their normal cold, damp environment. ...Read moreSee 1 more doctor answer
No: The meningicoccal vaccine is an attenuated (not live) vaccine and cannot be spread to others. ...Read more
Partial protection: Some vaccines give partial protection to some kids and these will be susceptable to infection by wild disease carriers. Some of the measles this year in houston were traced to an imported case infecting kids with no, one or two doses. The chickenpox vaccine has essentially ended CP deaths (were 50/yr) but we still see breakthru cases, all of which can develop secondary illnesses like invasive strep. ...Read more
YES: Yes, the RSV shot is not a true vaccine - its really a collection of antibodies to RSV to help neutralize and lesson the effects of future infections. It is not the same thing as the other vaccines your child gets. However, it should reduce the risk of serious complications cause by RSV if your child still gets infected. It is not 100% effective in preventing infection. ...Read moreSee 2 more doctor answers
