Most people stop thinking about vaccines after childhood. Unless a pharmacy reminder pops up or a doctor mentions one during a visit, adult immunizations tend to fall off the radar entirely.
But the adult vaccine schedule published by the CDC doesn't stop at 18. It continues through your 20s, 30s, 50s, and beyond. The CDC organizes its recommendations into four adult age brackets: 19-26, 27-49, 50-64, and 65 and older. New vaccines get added as you move through them.
This blog breaks down what the CDC recommends at 30, 50, and 65, what adult vaccines cost without insurance, and where to get them.
A few vaccines apply across all adult age brackets.
Influenza (flu). One dose annually. For adults 65 and older, the CDC notes a preference for the high-dose or adjuvanted formulations (HD-IIV3, RIV3, or aIIV3) over the standard-dose shot.
Tdap / Td. One dose of Tdap (tetanus, diphtheria, and pertussis), followed by a Td or Tdap booster every 10 years. Pregnant patients should receive one dose of Tdap during each pregnancy. A Td or Tdap dose may also be given for wound management.
COVID-19. The CDC schedule lists one or more doses of the current season's vaccine for adults 19 through 64, and two or more doses for adults 65 and older. Because COVID-19 guidance has changed several times, this is worth confirming directly with your doctor.
What vaccines do I need at 30? At 30 you fall into the CDC's 27-49 bracket. At this stage, the schedule is largely about catching up on anything missed earlier and staying current on boosters.
HPV (human papillomavirus). For adults 27 through 45, the CDC lists HPV vaccination under shared clinical decision-making. That means it isn't a routine recommendation for everyone in this age range, but it may be appropriate depending on your circumstances. It's a conversation to have with your doctor rather than a default.
MMR (measles, mumps, rubella). Adults born in 1957 or later should receive one or two doses depending on indication, if they lack documentation of vaccination or evidence of immunity.
Varicella (chickenpox). Adults born in 1980 or later should receive two doses if they lack documentation of vaccination or evidence of immunity.
Hepatitis A and Hepatitis B. Both appear on the adult schedule with dosing that varies by vaccine type and condition. Hepatitis A is 2, 3, or 4 doses depending on the vaccine. Hepatitis B is 2, 3, or 4 doses depending on the vaccine or condition.
Polio (IPV). If you were incompletely vaccinated, the CDC recommends completing the three-dose series. Self-report of previous doses is acceptable.
Several other vaccines on the schedule at this age (meningococcal ACWY, meningococcal B, Hib, and mpox) are recommended based on specific risk factors or indications rather than age alone.
What vaccines do I need at 50? Turning 50 moves you into the 50-64 bracket, and this is where the schedule adds three vaccines that weren't routine before.
Zoster recombinant (Shingrix). Two doses are recommended for all adults 50 and older. Before 50, the CDC only recommends it for adults with immunocompromising conditions. This is the clearest new addition at this age.
RSV (respiratory syncytial virus). For adults 50 through 74, the CDC lists RSV vaccination for those with an additional risk factor or other indication. It becomes a routine age-based recommendation at 75 and older.
Pneumococcal. This is the one most people get wrong. Pneumococcal vaccination begins at age 50, not 65. According to the CDC schedule notes, adults 50 or older who have not previously received a dose of PCV13, PCV15, PCV20, or PCV21, or whose vaccination history is unknown, should receive one dose of PCV15, PCV20, or PCV21. If PCV15 is used, a dose of PPSV23 follows at least one year later.
If you've had some pneumococcal vaccines in the past, the recommendation depends on which ones and when. The CDC has separate guidance for patients who previously received only PCV7, only PCV13, only PPSV23, or a combination. Your doctor can work out where you land.
Varicella also appears as a two-dose recommendation in this bracket, alongside the annual flu shot, Tdap booster, and COVID-19 doses already covered above.
What vaccines do I need at 65? The 65-and-older bracket changes a few things rather than adding a long list of new vaccines.
Influenza, high-dose or adjuvanted. At 65, the CDC indicates a preference for HD-IIV3, RIV3, or aIIV3 rather than the standard-dose flu vaccine.
COVID-19. The schedule lists two or more doses of the current season's vaccine for this age group, compared to one or more for younger adults.
RSV. At 75 and older, RSV vaccination becomes a routine age-based recommendation rather than a risk-based one. Between 65 and 74, it remains in the risk-factor category.
Pneumococcal. If you didn't receive a pneumococcal vaccine between 50 and 64, this is still recommended. The CDC also has specific guidance for adults who previously received both PCV13 and PPSV23, where the next step depends on whether the PPSV23 dose was given before or after age 65.
MMR. For adults 65 and older, the CDC schedule lists MMR for health care personnel specifically.
Shingrix and Tdap continue to apply if you haven't completed them.
If you're looking for adult vaccines near me without insurance, cost is usually the first question.
As of 2026, typical out-of-pocket costs at retail pharmacies:
Most clinics and pharmacies also add an administration fee of roughly $20 to $35 per injection.
In Knox County, the Health Department administers vaccines, and retail pharmacies (CVS, Walgreens, Walmart, Kroger) handle most routine adult immunizations including flu, Tdap, Shingrix, and pneumococcal.
What's harder to find is someone tracking the whole schedule for you. Most people don't know which bracket they're in, what they've already received, or what's overdue. That's a primary care function, not a pharmacy one.
If you don't have vaccination records, your doctor can order titers (blood tests that check for immunity) for diseases like hepatitis B, MMR, and varicella, then build a catch-up plan based on the results.
At Burkhart Direct Family Care in Knoxville, vaccines aren't administered in-office. But reviewing your immunization history during a wellness visit, ordering titers when records are missing, and mapping out what you're due for are all part of the membership. From there, you'll know exactly what to ask for when you get to the pharmacy or Health Department.
Because the hardest part of the adult vaccine schedule isn't getting the shot. It's knowing which ones you actually need.
