A Provider's Guide to Helping Patients Find Adacel

When patients can't find Adacel at their usual pharmacy, they often turn to their physician, nurse practitioner, or pharmacist for help. In the current environment — where Tdap demand is elevated due to the ongoing Td shortage — providers need practical strategies to guide patients toward successful vaccination.

This guide covers the tools, referral pathways, and communication approaches that can help your practice navigate Adacel availability challenges effectively. For real-time stock checking tools, visit MedFinder for Providers.

Understanding the Current Supply Landscape

A brief refresher on why patients are struggling to find Adacel:

• The Td vaccine shortage (triggered by MassBiologics discontinuing TdVax in March 2024) shifted enormous demand onto Tdap products.
• Adacel (Sanofi Pasteur) and Boostrix (GSK) are absorbing demand previously met by Td vaccines.
• The October 2025 FDA approval of repeat Adacel dosing after 8 years expanded the eligible population.
• Supply is adequate at the manufacturer level but distribution has been uneven, creating pharmacy-level stock-outs.

Tool #1: MedFinder for Providers

MedFinder for Providers is a free tool that lets you search for pharmacies with Adacel or Boostrix in stock by ZIP code. Here's how to integrate it into your workflow:

At the Point of Care

• When you write a Tdap order, check MedFinder to confirm stock at the patient's preferred pharmacy before they leave your office.
• If their pharmacy is out, identify an alternative with stock and update the order accordingly.
• Print or share the search results with the patient so they have a confirmed destination.

For Staff and Front Desk

• Train medical assistants and front-desk staff to use MedFinder when patients call about vaccine availability.
• Create a quick-reference card with the MedFinder URL and common search instructions for staff.
• Consider running a daily or weekly stock check for your area and posting results in your patient-facing materials.

For Follow-Up

• If a patient reports they couldn't fill their Tdap order, use MedFinder to identify new options during a phone follow-up or patient portal message.
• Set a tickler to follow up with deferred patients when supply improves.

Tool #2: Direct Pharmacy Coordination

Building relationships with your local pharmacies improves your ability to guide patients effectively:

Establish Preferred Pharmacy Contacts

• Identify 3-5 pharmacies in your practice area that reliably stock Tdap.
• Get direct phone numbers for pharmacy staff (not just the main store line).
• Ask each pharmacy to notify your practice when Adacel is restocked after a stock-out.

Cross-Reference Chain Pharmacy Systems

Many chain pharmacies can check inventory across locations within their system:

• CVS: Pharmacy staff can search inventory at nearby CVS locations.
• Walgreens: Similar inter-store inventory visibility.
• Walmart: Pharmacy team can check nearby Walmart locations.

When directing patients to a chain pharmacy, suggest they ask the pharmacist to check other stores in the area if their location is out.

Tool #3: Alternative Supply Channels

When standard retail pharmacy channels are exhausted, consider these alternatives:

Local and State Health Departments

• Many health departments maintain vaccine supplies through CDC-funded programs.
• Contact your local health department's immunization program to understand what's available.
• Some health departments will administer vaccines to patients referred by private providers.

Hospital-Based Pharmacies

• Hospital pharmacies often have separate supply chains and may have Adacel when retail pharmacies don't.
• For patients already seen in a hospital setting (ED, inpatient, outpatient clinic), check the hospital pharmacy's stock.

Vaccines for Children (VFC) Program

• If your practice participates in VFC, you can order Tdap for eligible patients (under 19, Medicaid, uninsured, underinsured, or American Indian/Alaska Native) through the program.
• VFC supply is separate from commercial supply and may be more reliable during shortages.

Sanofi Pasteur Direct

• Contact Sanofi Pasteur's customer service at 1-800-822-2463 for supply assistance.
• Sanofi can sometimes expedite shipments to practices experiencing critical shortages.

Stocking Vaccines In-Practice

If your practice doesn't currently stock Tdap vaccines, the current shortage environment may justify starting. Benefits include:

• Immediate patient access: Vaccinate at the point of care without pharmacy referral.
• Improved completion rates: Patients are more likely to get vaccinated when offered during a visit versus being sent elsewhere.
• Revenue opportunity: Vaccine administration generates reimbursement through medical and pharmacy benefits.

Practical Considerations

• Storage: Adacel requires refrigeration at 2-8°C (36-46°F). Ensure you have a dedicated vaccine refrigerator with continuous temperature monitoring.
• Ordering: Establish accounts with vaccine distributors (McKesson, AmerisourceBergen, Cardinal Health).
• State requirements: Check your state's immunization registry reporting requirements.
• Wastage management: With single-dose vials/syringes, waste is minimal. Order quantities aligned with your patient volume.

Patient Communication Strategies

Proactive Communication

Don't wait for patients to call asking about Adacel availability. Proactively address the issue:

• Add a note to your patient portal about current Tdap availability and how you're helping patients find supply.
• Include a MedFinder link in vaccine reminder messages.
• Train staff to mention availability proactively when scheduling vaccination appointments.

Managing Patient Frustration

Patients who've been turned away from multiple pharmacies may be frustrated. Helpful approaches:

• Validate their frustration: "I understand this is inconvenient, and I want to help you get vaccinated."
• Offer a concrete next step: "Let me check where Adacel is available near you right now."
• Reassure about alternatives: "Boostrix provides the same protection. Would you like me to look for that instead?"
• Share resources: "Here's a tool called MedFinder that can help you check stock in real time."

Handling Specific Patient Populations

Pregnant Patients

Maternal Tdap is time-sensitive (optimal at 27-36 weeks gestation). For pregnant patients:

• Check stock proactively at the 24-week visit so the vaccination can be scheduled for 27-28 weeks.
• Consider stocking Tdap in your OB-GYN practice for immediate administration.
• If Adacel is unavailable, administer Boostrix without delay.
• Share our patient guide: How to find Adacel in stock near you.

Adolescent Patients

The routine 11-12 year Tdap booster often coincides with school-entry requirements. For adolescents:

• Attempt vaccination at the well-child visit whenever possible.
• If stock is unavailable, schedule a follow-up specifically for vaccination and order the vaccine in advance.
• Communicate with parents about the timeline so school deadlines aren't missed.

Immunocompromised Patients

While vaccine response may be reduced in immunocompromised patients, Tdap is still recommended:

• Time vaccination optimally relative to immunosuppressive therapy cycles.
• Document clinical reasoning for vaccination timing.
• Ensure family members and close contacts are also vaccinated (cocooning strategy).

Building Resilience for Future Shortages

The Adacel availability challenge is a reminder that vaccine supply disruptions can happen with any product. Build resilience now:

• Diversify vaccine suppliers — Maintain accounts with multiple distributors.
• Build safety stock — Keep 2-4 weeks of supply above your minimum par level for critical vaccines.
• Create shortage protocols — Document your practice's standard operating procedures for vaccine shortages, including triage criteria and alternative sourcing steps.
• Stay informed — Subscribe to ASHP drug shortage alerts, CDC vaccine supply updates, and manufacturer communications.
• Use MedFinder — Make MedFinder for Providers a standard tool in your practice's toolkit.

The Bottom Line

Helping patients find Adacel during supply challenges requires proactive effort — but the tools and strategies exist to make it manageable. Use MedFinder for Providers for real-time stock visibility, build relationships with local pharmacies, consider stocking vaccines in-practice, and communicate proactively with patients about availability and alternatives.

Your patients are counting on you to help them stay protected. With the right approach, you can ensure Tdap vaccination happens even when supply is tight.
