For the schedule of vaccinations for infants and children, see Fig. 3: Approach to the Care of Normal Infants and Children: Recommended childhood and adolescence immunization schedule. (see also the Centers for Disease Control and Prevention's National Immunization Program 2007
Childhood and Adolescent Immunization Schedule).
For vaccinations to be considered for all adults, see Table 2: Immunization: Common Vaccinations for Adults (see also the Centers for Disease Control and Prevention's National Immunization Program Adult
Immunization Recommendations). Uses of nonroutine active vaccines (eg, for rabies, typhoid, yellow fever, and mycobacterial infections) and some routine vaccinations are discussed under specific disorders elsewhere in The Manual.
Diphtheria-Tetanus-Pertussis
Preparations:
Diphtheria (D) vaccines contain toxoids prepared from Corynebacterium diphtheriae. Tetanus (T) vaccines contain toxoids prepared from Clostridium
tetani. Acellular (a) pertussis (P) vaccines contain semipurified or purified components of Bordetella
pertussis. Whole-cell pertussis vaccine is no longer available in the US because of concerns about adverse effects, but it is still available in other parts of the world. There are 2 preparations of the acellular vaccine:
Tdap contains lower doses of diphtheria and pertussis components (indicated by the lower case d and p).
Administration:
The vaccine is given as 5 primary and 1 booster IM injections during childhood as follows: the first 3 doses at 2-mo intervals, starting at age 2 mo; the 4th at age 12 to 15 mo; and the last before school entry at age 4 to 6 yr. A single booster of Tdap is given at age 11 or 12 yr.

Adverse effects:
Adverse effects are rare and are mostly attributable to the pertussis component. They include encephalopathy within 7 days; a seizure, with or without fever, within 3 days; persistent, severe, inconsolable screaming or crying for ≥ 3 h; collapse or shock within 48 h; temperature of ≥ 40.5° C, unexplained by another cause, within 48 h; and immediate severe or anaphylactic reaction to the vaccine. These reactions contraindicate further use of pertussis vaccine; combined diphtheria and tetanus vaccine is available without the pertussis component.
Mild adverse effects include redness, swelling, and soreness at the injection site.
Tetanus-Diphtheria
Although tetanus is rare in the US, it has a high mortality rate. Because 1/3 of cases occur unpredictably (after minor or inapparent injuries), universal tetanus vaccination remains necessary.
Preparations:
The most widely used preparations combine tetanus toxoid with diphtheria toxoid (Td for adults, DT for children); a preparation with only tetanus toxoid (TT) is also available. Td contains a lower dose of diphtheria toxoid than DTaP and DT, used in children.
Administration:
Td boosters, 0.5 mL IM, are given q 10 yr after the Tdap booster that is given at age 11 to 12 yr. Boosters are needed to maintain immunity. Because the incidence of pertussis is increasing, at least one booster before age 65 should be Tdap. Adults who missed the primary series of vaccinations in childhood should receive it as adults.
Adverse effects:
Adverse effects are very rare. They include anaphylactic reactions, Guillain-Barré syndrome, and brachial neuritis. Mild effects include redness, swelling, and soreness at the injection site.
Haemophilus
influenzae Type b
Preparations:
These vaccines are prepared from the purified capsule of Haemophilus influenzae type b (Hib). All Hib vaccines use polyribosylribitol phosphate (PRP) as the polysaccharide, but 4 different protein carriers produce 4 different Hib conjugate vaccines: diphtheria toxoid (PRP-D), Neisseria
meningitidis outer membrane protein (PRP-OMP), tetanus toxoid (PRP-T), and diphtheria mutant carrier protein CRM197 (HbOC).
Administration:
A primary series is given in 3 IM doses at age 2, 4, and 6 mo or in 2 IM doses at age 2 and 4 mo, depending on the formulation. In either case, a booster is recommended at age 12 to 15 mo. Some adults at increased risk (eg, because of AIDS or asplenia) may benefit from this vaccine.
Adverse effects:
Adverse effects are rare. They can include pain, redness, and swelling at the injection site.
Hepatitis
A
Preparations:
Hepatitis A vaccines are prepared from formalin-inactivated, cell culture–derived hepatitis A virus. There are 2 formulations; either can be used in children or adults.
Administration:
The vaccine is given in 2 IM doses 6 mo apart. It is recommended for children aged 12 to 18 mo and for older children and adults who are at increased of the disease (see Table 2: Immunization: Common Vaccinations for Adults).
Adverse effects:
No serious adverse effects have been reported. Mild effects include pain and occasionally induration at the injection site.
Hepatitis
B
Preparations:
Hepatitis B vaccine uses recombinant DNA technology. Single-antigen and combination formulations are available.
Administration:
The vaccine is given in 2 or 3 IM doses, depending on the formulation. Universal vaccination is recommended beginning at birth.
Adverse effects:
Serious adverse effects are very rare and include anaphylaxis. Mild effects include pain at the injection site and occasionally an increase in temperature > 38°C.
Human
Papillomavirus
Preparations:
Recombinant technology is used to prepare the vaccine. The vaccine is made from HPV-like particles (VLP) from the serotypes 6, 11, 16, and 18, which cause 70% of cervical cancers and 90% of genital warts.
Administration:
The vaccine is given in 3 IM doses: initially, then at 1 to 2 and 4 to 6 mo after the initial dose. It is recommended for females aged 11 to 13 but can be given as early as age 9 or up to age 26 for catch-up. Vaccination is not recommended after age 26.
Adverse effects:
No serious adverse effects have been reported. Mild effects include redness, swelling, and tenderness at the injection site.
Influenza
Preparations:
Influenza vaccines may be inactivated trivalent vaccines (TIV) or live-attenuated vaccines (LAIV). Each type targets 3 virus strains (2 from influenza A and 1 from influenza B). Because antigenic drift is continual, 1 or 2 strains are changed each year in anticipation of the expected predominant influenza strains. An inactivated vaccine against avian influenza has been developed but is not commercially available. It is being nationally stockpiled in case person-to-person transmission of avian influenza becomes possible.
Administration:
The vaccine is required annually for at-risk patients because of antigenic drift. Because outbreaks usually begin in early winter or midwinter, the vaccine is given in the fall, usually October and November in the Northern Hemisphere.
TIV, given as a single IM injection, is recommended for people at high risk of serious sequelae, including children aged 6 mo to 8 yr and anyone > 50 yr (see Table 2: Immunization: Common Vaccinations for Adults), as well as anyone who requests vaccination.
LAIV, given as an intranasal spray, is indicated for healthy people aged 2 to 49 yr; it is contraindicated during pregnancy.
Adverse effects:
Rarely, TIV has adverse effects, such as Guillain-Barré syndrome, anaphylactic reactions, soreness at the injection site, and fever. Adverse effects of LAIV are unusual; they include possible triggering of asthma and transmission of the virus to unimmunized contacts.
Egg protein is used in both vaccine types; thus, the vaccine is contraindicated for people who have severe anaphylactic reactions to egg protein.
Measles,
Mumps, and Rubella
Preparations:
The vaccine contains live-attenuated virus prepared in chicken embryo cell cultures. Measles vaccine is available as a single-antigen (measles-only) vaccine or combined with rubella (MR), mumps and rubella (MMR), or mumps, rubella, and varicella (MMRV). There are also single-antigen vaccines for mumps, rubella, and varicella.
Administration:
Most commonly, the combination vaccine MMR or MMRV is given sc. The vaccine should be given to all children in their 2nd yr of life, typically at age 12 to 15 mo, with a 2nd dose at age 4 to 6 yr. Adults at risk include those who have never received the vaccine and have never become naturally infected. Generally, people born before 1956 are considered immune because infection during their childhood was ubiquitous. Unless the vaccine is contraindicated, people who were born after 1956 and have not had 2 doses of the vaccine or the infections should receive at least one dose of the combined vaccine; people who have been or are likely to be exposed (eg, college students, health care workers, international travelers) should receive a 2nd dose.
Although the components of the vaccine can be given separately, the combined form is preferred because people who need one vaccine probably need all 3, and revaccination poses no particular risk.
Adverse effects:
A mild, noncommunicable infection occurs in 15% of vaccine recipients. Symptoms appear 7 to 11 days after immunization and include fever, malaise, and a measles-like exanthem. Mumps vaccine has adverse effects only rarely; they include encephalitis (only from a Japanese mumps vaccine strain), seizures, nerve deafness, parotitis, purpura, rash, and pruritus.
Rubella vaccine can cause joint pain, usually in the small peripheral joints 2 to 8 wk after immunization, in < 1% of infants but in ≤ 26% of women. Rash or lymphadenopathy occasionally occurs. The vaccine is not recommended for pregnant women because of the theoretic risk to the fetus. However, inadvertent administration during pregnancy does not necessarily mean a therapeutic abortion is recommended because the actual fetal risk may be nil.
With all of the vaccine formulations, local adverse effects are unusual and include soreness at the injection site.
Pneumococcal
Disease
Preparations:
Pneumococcal conjugate vaccine (PCV7) contains 7 purified capsular polysaccharides of Streptococcus
pneumoniae; each is coupled to a variant of diphtheria toxin. Pneumococcal polysaccharide vaccine (PPV23) contains antigens from the 23 most virulent of the 83 subtypes of S. pneumococcus. Unlike the older 23-valent vaccine, PCV7 can stimulate antibody responses in infants. It also seems to confer greater protection against invasive pneumococcal disorders than PPV23. PPV23 reduces bacteremia by 56 to 81% in adults overall but is less effective in debilitated elderly people. It reduces pneumonia incidence only minimally.
Administration:
PCV7 is recommended as a 4-dose IM series for infants at age 2, 4, 6, and 12 to 15 mo. Children at high risk of pneumococcal disease (eg, children with sickle cell disease, asplenia, or a chronic disorder) should receive a dose of PPV23 at age 24 mo and an additional dose 3 to 5 yr after the first. PPV23 should be given to any older child or adult at high risk of pneumococcal disease (see Table 2: Immunization: Common Vaccinations for Adults). One immunization is recommended for lifetime protection; however, revaccination after 5 yr should be considered for patients at particularly high risk.
Adverse effects:
Adverse effects are usually mild and include fever, irritability, drowsiness, anorexia, vomiting, and local erythema.
Poliomyelitis
Preparations:
Inactivated poliovirus vaccine (IPV) contains a mixture of formalin-inactivated poliovirus types 1, 2, and 3. IPV may contain trace amounts of streptomycin , neomycin , and polymyxin B . A combination vaccine with IPV, DTaP, and hepatitis B is also available. The live-attenuated oral formulation is no longer available in the US because it causes polio in about 1 of every 2.4 million people who receive the vaccine.
Administration:
A 4-dose IM series is given at age 2 mo, 4 mo, 6 to 18 mo, and 4 to 6 yr. Typically, a combination vaccine is used for the first 3 vaccinations and a single-antigen vaccine for the last dose.
Adverse effects:
No adverse effects have been associated with IPV. Because it may contain trace amounts of neomycin , streptomycin , and polymyxin B , people who are sensitive to any of these drugs may have an allergic reaction to the vaccine.
Varicella
Preparations:
The vaccine contains an attenuated wild strain of varicella and trace amounts of gelatin and neomycin . It is available as a single-antigen vaccine or as a combination vaccine with MMR.
Administration:
The vaccine is given sc in 2 doses: at age 12 to 15 mo and at age 4 to 6 yr. The 2nd dose is a new recommendation; thus, a catch-up dose is suggested for children, adolescents, and adults who have received only one dose. The vaccine should be given to all children and to young adults not previously infected, especially health care practitioners and close contacts of immunocompromised patients. If adults have not had varicella, levels of protective antibodies should be measured to determine the need for vaccination. No immune globulins, particularly varicella-zoster immune globulin, should be given within 5 mo before or 2 mo after vaccination because immune globulins may prevent development of protective antibodies.
Adverse
effects:
Adverse effects are minimal and include transient pain, tenderness, and redness at the injection site. Occasionally, within 1 mo of vaccination, a mild maculopapular or varicella-like rash develops. Patients who develop this rash should avoid contact with immunocompromised people until it resolves. Spread of the virus from vaccine recipients to susceptible people has been documented in < 1% of recipients but only from those who developed a rash.
Because Reye's syndrome can develop, recipients < 16 yr should avoid salicylates for 6 wk.
Herpes
Zoster
Preparations:
The vaccine contains an attenuated wild strain of varicella, similar to the varicella vaccine but with a higher amount of the attenuated virus.
Administration:
The vaccine is recommended for adults ≥ 60 yr regardless of prior infection. It is given sc.
Adverse effects:
No serious adverse effects have been reported. Soreness at the site of the injection may occur.
Simultaneous
Administration of Different Vaccines
Simultaneous administration is safe, effective, and convenient; it is particularly recommended when children may be unavailable for future vaccination or when adults require multiple simultaneous vaccines (eg, before international travel). Simultaneous administration may involve combination vaccines (see Table 1: Immunization: Vaccines Available in the US) or use of ≥ 1 single-antigen vaccines. More than one vaccine may be given at the same time using different injection sites and syringes. If live-virus vaccines (varicella and MMR) are not given at the same time, they should be given at least 4 wk apart.
Immunizations
for Travelers
Immunizations may be required for travel to areas where infectious diseases are endemic. The Centers for Disease Control and Prevention can provide information; a telephone service (1-877-394-8747) and web site (www.cdc.gov/travel/vaccinat.htm) are available 24 h/day.
