I second gjm's suggestion to talk to a healthcare professional.

Every year, the CDC updates and publishes their recommended immunization schedule for adults (patient version), which doesn't assume childhood vaccination. Below, I've summarized the parts that are most relevant to you.

Vaccines recommended for adults aged 30 years:

• Influenza (annually)
• Tdap (with Td booster every 10 years)
• Varicella (2 doses)
• MMR

Additional vaccines recommended for adults aged 30 years with diabetes:

• Zoster
• PPSV23
• Hepatitis B (3 doses)

Note that if you have a concurrent immunocompromising condition (e.g., lymphoma), then live vaccines should generally be avoided. This includes the varicella, MMR, and zoster vaccines. Again, your healthcare provider can tell you more.
