Why should I join Main Street Vaccines?

How do I order?

Sanofi Pasteur:

Sanofi vaccines must be ordered through Sanofi Pasteur or its wholly owned subsidiary, VaxServe, to receive pricing.

Sanofi Pasteur: | 800-VACCINE | Contact your Sanofi Pasteur Rep
VaxServe: | 800-752-9338 | Contact your VaxServe Rep

Please note: Sanofi Pasteur and VaxServe provide a discount for ordering online.

If you purchase Sanofi Pasteur vaccines through an indirect distributor, you will not receive Main Street Vaccines pricing and those purchases will not accrue toward your Main Street Rewards bonus under the Sanofi Pasteur contract.


Merck vaccines can be ordered directly through Merck or indirectly through a Merck authorized Prime Distributor.

Merck: | 877-VAX-MERCK | Contact your Merck Rep
Prime Distributor: click here for a current list of Merck authorized Prime Distributors.

It is important, when ordering through a Distributor, that prior to placing your order you must:

  1. Confirm the distributor is a Prime Distributor authorized by Merck; and
  2. Confirm you are properly set up in their system to receive contract pricing.

Please note: Final invoice charges and payment/shipping/return policies may not be the same for Merck and its Prime Distributors and may vary between Distributors.

Pfizer Trumenba®:

Pfizer Trumenba® must be ordered directly from Pfizer to receive contract pricing. | 800-572-8221 OPT #2 | Contact your Pfizer Rep

Are your vaccine contracts connected?

No, our contracts are separate and independent from each other. Enrollment in one contract does not mean you are enrolled in another contract. Practices may enroll in any combination of contracts that suit their needs. Maximum savings and bonuses are achieved by enrolling in all of our contracts.

What other benefits do your members get?

Currently, we offer discounted prices on medical grade vaccine refrigerators & freezers, access to our Staples Business Advantage discount office supplies program, and a discount to members who switch from their current EHR to Office Practicum. Additionally, DocSavings offers the best prices on office cryosurgery systems and competitively priced medical supplies.

VaxServe sells Merck and Pfizer vaccines, can I purchase those vaccines at VaxServe?

To get our Pfizer agreement prices for and terms for the purchase of Trumenba®, you need to be separately enrolled in that contract and order directly from Pfizer.

To get Merck pricing you must be separately enrolled in that contract. Once enrolled Merck vaccines may be purchased directly from Merck or from a Merck authorized Prime Distributor at your election. A current list of Prime Distributors can be found on

Sanofi Pasteur vaccines must be ordered through Sanofi Pasteur or VaxServe.

How long do I have to stay with one of your contracts?

Our contracts renew automatically, but you may withdraw at any time. Please notify us in writing or by email at if you wish to cancel your enrollment. You will lose any accrued benefits if you withdraw prior to the close of the current contract year. Our contract year runs from July 1st through June 30th.

What happens if I get a “deal” somewhere or purchase competing vaccines?

We offer a very good long term “deal” but we know our prices can be beaten by limited promotions or incentives. Experience has shown us that stability and steady savings outweigh short-term deals and gimmicks over time.

Members who persistently violate the contract terms may lose their bonus or be removed to preserve benefits for the group.

Can you really tell if I am buying vaccines outside the contract?

Yes, the data is publicly available and we monitor it regularly. It is important for our contract integrity.

Can I be in more than one Physician Buying Group (PBG) at the same time?

No, not for vaccines. By the terms of each contract, Sanofi Pasteur, Merck and Pfizer, you are only allowed to be enrolled with one GPO per contract.

Do we get preferential treatment if vaccines are scarce?

Not specifically; however, we work closely with our vaccine partners to obtain contract adjustments and allocations. We post updates about availability on our website and distribute information through our newsletter.

What happens if a manufacturer can’t deliver on contracted vaccines?

In a designated “failure to supply” situation we usually arrange a temporary release from the contract terms and/or a compensatory price adjustment.

Can I use a credit card to pay for vaccine orders?

Absolutely. Many of our practices do this, as it generates enormous rewards or rebates on your credit card accounts.

Do I have to change the way I order under your agreements?

No. Our programs are designed to simplify your life, not complicate it. There are no ratios or volume requirements. There is one simple requirement—that members be brand loyal to the contracts they participate in. The ordering and shipment process of vaccines is not altered in any way by participation in our contracts. Ordering, shipping, and payments for both Sanofi Pasteur vaccines and Pfizer’s Trumenba® must be done directly through the respective companies. Merck vaccines may be ordered directly from Merck or from any authorized Merck Prime Distributor.

What happens if one of the companies runs a special sale?

We hope you take advantage of it. In addition to our contracted pricing and terms, our members are still eligible to take advantage of any additional discount our partners offer.

My state provides basic childhood vaccines so I don’t use all of the vaccines that you mention in your contracts; can I still participate and get discounts?

Absolutely. This question usually references the newer adolescent and adult vaccines that some states cannot afford to provide. Our prices and bonuses are based on the products you purchase, so this would only be an issue if, for example, you used our contracts to receive great rates on Menactra®, Gardasil®, or Trumenba®, but purchased competing vaccines for the rest of your immunization schedule.

I get a lot of my vaccines for Medicaid or indigent patients through VFC or another state plan. Do I have to use vaccines from your contract partners?

Not absolutely – but why wouldn’t you? Their products are available through all VFC plans. Immunization protocols are complicated enough – why keep two or more sets of stock and schedules?

I see mostly adults, (or women, or subspecialty patients), so I don’t use childhood vaccines. Can I order just the products I need and still get the benefits of your contracts?

Certainly. As long as you are not ordering childhood or adolescent/adult vaccines from another source, we usually waive our requirements.

I have gotten a better price quote on your vaccines from another buying group. How is that possible?

It isn’t as long as you are comparing apples to apples. Your competing quote may include various manufacturer discounts and incentives as part of the base price.

I’m already a Main Street member. Why don’t I get your prices for all my vaccines?

Although you are a member of Main Street Vaccines, you still need to enroll in each contract individually to receive its benefits. Also, please make sure that you are ordering through the approved channels, or your purchases will not be eligible for the contract prices and terms.
