Hep B Vaccine is usually administered at birth, but if not, the minimum age for the final dose is 24 weeks. Hep B is transmitted by blood or bodily fluids and a part of the Hepadna family.
PCV13 vaccine is for a bacterial infection of the lung that often leads to pneumonia.
Influenza vaccines are now dependent upon the 2009 H1N1 vaccine. Dosages vary because the 2010-2011 influenza vaccine now contains both the seasonal influenza and H1N1 vaccines. Influenza is a part of the orthomyxo family.
Hib vaccine, haemophilus influenza type b vaccine is now recommended for children under the age of 5 in the US. The vaccine is expected to prevent meningitis, pneumonia, epiglottis, etc. The illness is caused by a bacteria, but the guidance is that people older than age 5 should consider the vaccine if they have sickle cell disease, leukemia, HIV infection or have had a splenectomy.
HPV is commonly spread through sexual contact and is part of the papilloma family. There are as many as 40 types of HPV, which can lead to cervical cancer or genital warts. HPV 4 and HPV2 are recommended to prevent cervical cancers, but it is now recommended that males receive the HPV4 vaccine as a protection against genital warts.
Interestingly, the CDC has an Advisory Committee on Immunization practices (ACIP_ who update vaccine recommendations every three to five years. It must be difficult to sort out all the vaccines and understand their modes of action to ensure they do not interfere. Constant research must be done to analyze recommended dosages and ideal vaccine schedules.
