Vaccinations in Adults
The Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) annually reviews the recommended adult immunization schedule to ensure that the schedule reflects current recommendations for the licensed vaccine. Vaccines are recommended for adults on the basis of their age, prior vaccinations, health conditions, lifestyle, occupation, and travel. [1]
Vaccines recommended for routine immunization are discussed below. Note that the following vaccines also may be recommended for additional age groups depending on risk factors.
For the CDC’s current specific vaccination recommendations by vaccine and age group, recommendations based on medical and other indications, and contraindications and precautions, please refer to the CDC’s Adult Immunization Schedules. [1]
COVID-19
1 dose annually after initial vaccination series
Unvaccinated
-
1 dose of Moderna or Pfizer-BioNTech vaccine
-
2-dose series of Novavax vaccine at 0, 3-8 weeks
Previously vaccinated with 1 or more doses of any COVID-f19 vaccine
-
1 dose of updated formula at least 8 weeks after most recent COVID-19 vaccine dose
Moderately or severely immunocompromised individuals
-
Refer to CDC recommendations at https://www.cdc.gov/vaccines/hcp/imz-schedules/downloads/adult/adult-combined-schedule.pdf
Influenza
1 dose annually
-
Influenza virus vaccine, intranasal (aged < 50 years)
-
Influenza virus vaccine, adjuvanted (aged 65 years and older)
Various influenza vaccines have been approved that are directed toward patients with egg allergy (eg, Flucelvax, Flublok) [2] and for elderly adults to provide a stronger immune response (eg, Fluzone High-Dose, Fluad). [3]
Adults with a history of egg allergy who have only hives after exposure to egg should receive age-appropriate inactivated influenza (IIV) or recombinant influenza vaccine (RIV). Adults with a history of egg allergy with symptoms other than hives (eg, angioedema, respiratory distress, lightheadedness, recurrent emesis, or who required epinephrine or other emergency intervention) may receive age-appropriate IIV or RIV. The selected vaccine should be administered in an inpatient or outpatient medical setting and supervised by a healthcare provider who is able to recognize and manage severe allergic conditions. [2]
Respiratory syncytial virus (RSV) vaccine
FDA approval: Adults aged 60 years and older
CDC ACIP recommendations
-
All adults aged 75 years and older: 1 dose of RSV vaccine
-
Adults aged 60-74 years at increased risk for severe RSV disease: 1 dose of RSV vaccine
-
For more information, see https://www.cdc.gov/mmwr/volumes/73/wr/mm7332e1.htm
FDA approval (Abrysvo): Pregnant women at 32 through 36 weeks gestation
RSV vaccine, adjuvanted (Arexvy)
Tetanus, diphtheria, pertussis
Every 10 years
-
Tetanus and reduced diphtheria toxoids/acellular pertussis vaccine (Tdap; Boostrix, Adacel)
-
Regardless of the interval since receiving their last tetanus or diphtheria toxoid-containing vaccine, persons aged 19 years or older who have never received a dose of Tdap should receive 1 dose of Tdap.
-
To ensure continued protection against tetanus and diphtheria, booster doses of either Td or Tdap should be administered every 10 years throughout life. [1]
Varicella
2 doses for adults without evidence of immunity
Measles, mumps, rubella (M-M-R II, Priorix)
One or 2 doses should be documented for adults born after 1957. [1]
-
Adults aged 19-59 years: 0.5 mL SC; administer a second dose 28 days later for high-risk adults
-
Adults aged 50 years or older: 0.5 mL SC; administer 1 dose only
Hepatitis B
Adults aged 19-59 years: Complete a 2- or 3- or 4-dose hepatitis B vaccine series
Aged 60 years and older: Vaccinate if known risk factors exist; optional if no risk factors
Regimens
-
2-dose series only applies when 2 doses of Heplisav-B are used at least 4 weeks apart
-
3-dose series Engerix-B, PreHevbrio, or Recombivax HB at 0, 1, 6 months (minimum intervals: dose 1 to dose 2 [4 weeks]; dose 2 to dose 3 [8 weeks]; dose 1 to dose 3 [16 weeks])
-
3-dose series HepA-HepB (Twinrix) at 0, 1, 6 months (minimum intervals: dose 1 to dose 2 [4 weeks]; dose 2 to dose 3 [5 months])
-
4-dose series HepA-HepB (Twinrix) accelerated schedule of 3 doses at 0, 7, and 21-30 days, followed by a booster dose at 12 months
Human papillomavirus 9-valent (HPV)
The following are recommendations for the HPV 9-valent vaccine:
-
Adolescents and adults aged 15-26 years: 2-3 doses (depending on vaccination history) if immunization series was not completed during childhood (ie, age 9-14 years) [5]
-
Adults aged 27-45 years: Need for vaccination based on shared decision making between patient and clinician
Zoster
Two doses of recombinant zoster vaccine (RZV)
-
Administer 2 doses of RZV (Shingrix) 2-6 months apart to adults aged 50 years or older regardless of past episode of herpes zoster or receipt of ZVL (Zostavax)
-
Adults younger than 50 years with immunocompromising conditions should receive 2 doses
Pneumococcal vaccines
The following are recommendations for pneumococcal vaccines:
-
Aged 65 years and older: 1 dose PCV15 or 1 dose PCV20 [7]
-
If PCV15 is administered, follow with a dose of PPSV23 given at least 1 year after the PCV15 dose
-
A minimum interval of 8 weeks between PCV15 and PPSV23 can be considered for adults with an immunocompromising condition, cochlear implant, or cerebrospinal fluid leak to minimize the risk for invasive pneumococcal disease caused by serotypes unique to PPSV23 in these vulnerable groups
-
Adults aged 19-64: ACIP guidelines recommend use for adults with immunocompromising conditions, cerebrospinal fluid leak, or cochlear implant. [7]
-
Pneumococcal vaccine 20-valent (PCV20) once, OR
-
Pneumococcal vaccine 15-valent (PCV14) once plus Pneumococcal vaccine polyvalent (PPSV23) administered 1 year after PCV15
