New Pneumococcal Vaccine PCV13 Replaces PCV7
PCV13 and PCV7 are manufactured in a similar fashion and PCV13 will replace PCV7 for prevention of pneumococcal disease in children. Because PCV7 has been used since 2000 there is now significantly less pneumococcal disease caused by the seven strains. Even though there is less disease overall, other strains of Streptococcus pneumoniae that are not in PCV7 have become more common. PCV13 includes 6 additional serotypes, protecting against more disease than PCV7. In particular, PCV13 vaccine protects against serotype 19A, which has become the most common pneumococcal serotype and is often resistant to antibiotics.
Should children who already received the full 4-dose vaccine series of PCV7 be vaccinated with additional dose(s) of PCV13? Yes, children 12 through 59 months of age who are fully vaccinated with 4 doses of PCV 7 should receive a single, supplemental dose of PCV13 no sooner than 8 weeks after the last dose of PCV7. It does not matter whether a child received the PCV7 doses on time or used a catch-up schedule and may have received less than 4 doses as part of an age-appropriate complete schedule. For older children (up through 71 months) who have an underlying medical condition (e.g., sickle cell disease, HIV infection, or other immunocompromising condition) and are completely vaccinated with PCV7, a single dose of PCV13 is recommended.
Second Dose of Influenza for 2010-2011 Flu Season for Any Child Not Receiving H1N1 Vaccine Last YearFrom the CDC's Advisory Committee on Immunization Practices (ACIP) Resolution No. 06/10-2All children ages 6 months through 8 years who receive a seasonal influenza vaccine for the first time should be given 2 doses. Children who receive only one dose of a seasonal influenza vaccine in the first influenza season they receive vaccine should receive two doses, rather than one, in the following influenza season. In addition, for the 2010-11 influenza season, children ages 6 months through 8 years who did not receive at least 1 dose of an influenza A(H1N1) 2009 monovalent vaccine should receive 2 doses of a 2010-11 seasonal influenza vaccine, regardless of previous influenza vaccination history. Children ages 6 months through 8 years for whom the 2009-10 seasonal vaccine or influenza A(H1N1) monovalent vaccine history cannot be determined should receive two doses of a 2010-2011 seasonal influenza vaccine.
