3 COVID-19 vaccines are authorized in the United States: two messenger ribonucleic acid (mRNA) vaccines (Pfizer-BioNTech and Moderna) and one viral vector vaccine (J&J).
Diphtheria, Tetanus and Pertussis
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants and Children Adolescents and Adults For More Information Important Information for Obstetric Providers Disease Diphtheria disease is mediated by the toxin of the aerobic gram-positive bacterium Corynebacterium diphtheria. The incubation period is generally 2-5 days. Diphtheria can infect almost any mucous membrane, but most […]
Haemophilus influenzae type b
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants Children, Adolescents and Adults For More Information Important Information for Obstetric Providers Disease Haemophilus influenzae is an aerobic gram-negative coccobacillus bacterium with encapsulated typeable strains and unencapsulated nontypeable strains. There are six serotypes of encapsulated Hib, identified by their antigenically and biochemically distinct polysaccharide […]
Hepatitis A
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants Children, Adolescents and Adults For More Information Important Information for Obstetric Providers Disease Hepatitis A Virus (HAV) is a nonenveloped RNA picornavirus that enters the body through the mouth via the fecal-oral route of transmission and replicates in the liver. Infected persons excrete virus […]
Hepatitis B
Recommendations The Institute for Vaccine Safety disagrees with the ACIP and CDC’s December 2025 changes to their Hepatitis B vaccination recommendations. Three decades of scientific evidence find the routine administration of hepatitis B vaccination for newborns to be very safe. We fear that rescinding the universal recommendation for Hepatitis B vaccination at birth, without ensuring […]

Measles, Mumps and Rubella
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants and Children Adults All Age Groups For More Information Important Information for Obstetric Providers Disease Measles is a highly contagious acute disease caused by an RNA paramyxovirus, genus Morbillivirus, with one antigenic type. Measles is transmitted via the respiratory route and secondary attack rates […]
Meningococcal
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Recommendations Adolescents All Age Groups For More Information Important Information for Obstetric Providers Disease Neisseria meningitidis, or meningococcus, is an aerobic gram-negative diplococcus. Meningococci colonize the nasopharynx, and in less than 1% of colonized persons the organism invades the bloodstream. Most strains are not pathogenic; […]
Pneumococcal
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Recommendations Infants Children, Adolescents and Adults For More Information Important Information for Obstetric Providers Disease Streptococcus pneumoniae is a facultative anaerobic gram-positive bacterium. 92 serotypes of S. pneumoniae have been documented, classified by their antigenic polysaccharide capsules. Antibodies provide protection specific to serotype. Pneumococci are […]
Polio
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Recommendations Infants Children Adults For More Information Important Information for Obstetric Providers Disease Poliovirus is an RNA enterovirus of the Picornaviridae family. Transmission is primarily through the fecal oral route, and the virus replicates in the pharynx, local lymphatics and gastrointestinal tract. Spread of the […]
Respiratory Syncytial Virus (RSV)
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Recommendations Infants Children Adults For More Information Important Information for Obstetric Providers Disease Respiratory syncytial virus (RSV) is an RNA virus of the genus Orthopneumovirus. There are two main types of human RSV (Type A and Type B). Most subtypes are determined by antigenic drift […]
Rotavirus
Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants For More Information Important Information for Obstetric Providers Disease Rotavirus is a very stable double-stranded RNA virus of the Reoviridae family. There are five predominant strains which historically have accounted for 90% of isolates in the United States, 75% of which being the G1 […]

Recommendations Recommendations from the Advisory Committee on Immunization Practices (ACIP) Infants and Children Adolescents and Adults For More Information Important Information for Obstetric Providers Disease Varicella is a highly infectious acute disease caused by the DNA herpesvirus varicella zoster virus (VZV). VZV is transmitted via the respiratory route. The incubation period generally lasts about 15 […]
