Herd Immunity

Vaccinating your child is the one way that you can shield them from getting some seriously harmful diseases. But did you know that when you vaccinate your child you are also helping to keep other children safe from harmful diseases? You are! And you are especially helping prevent disease in those children who are too sick to get vaccines for themselves. A phenomenon called herd immunity occurs when most of the people in a community are vaccinated against a disease, leaving no one to carry it, and thus, protecting those people who cannot be vaccinated. This way, even those who are not eligible for certain vaccines—such as babies, pregnant women, or people who are sick with immune system-compromising illnesses—get some protection. 

Haemophilus influenzae type b (Hib) vaccine


I once heard someone say that when you sneeze, droplets of saliva fly through the air and can land five feet away.Five feet!? Yuck! I’m not sure EXACTLY how far those droplets are carried through the air, but what I am sure of is that within those droplets are potentially millions of viral particles and thousands of bacterial cells.

One nasty bacteria in particular, called Haemophilus influenza (H. influenza), may be living in your nose and throat at all times and you do not even know it. In fact, you may not have ever come down with the illness and still have it in your body. And unfortunately, should someone who has it cough or sneeze and your child inhales the particles, it has the potential to make your child life-threateningly ill.

Rotavirus Vaccine (RV)


My one year old loves to stick everything she can into her mouth, including her fingers, toys, things that aren’t toys, the shopping cart handle–what I’m eluding to here is that children aren’t always the most clean creatures. However, they are cute, and we as parents want to protect them. It’s because of vaccines that we actually CAN protect them from some of the worst diseases. There’s one horrible virus in particular that’s highly contagious and loves to live on the surfaces of infected items, and that’s the rotavirus.

Hepatitis B (HepB) Vaccine


The hepatitis B vaccine (HepB) used currently in the United States is synthetically made from recombinant DNA. Let me break that statement down and tell you exactly what it means. This vaccine is considered synthetic because it is entirely made in a lab and contains no human blood products. Why would it ever contain human blood, you ask. Well, the virus is found in human blood, so you may suspect that human blood would be used to make the vaccine. In this case, no human products are ever used in the making of the vaccine, and let me tell you why: because of the use of recombinant DNA techniques.
