Monkeypox (MPX)

Updated 10/17/22

MPX is a rare disease caused by infection with the monkeypox virus.  Monkeypox can infect animals, such as monkeys and rodents, as well as humans.  The monkeypox virus belongs to the same group of viruses that cause smallpox and is not related to chicken pox.  The first case of  human monkeypox was recorded in 1970.  Since then, monkeypox has been reported in people in several other central and western African countries.  Prior to the current outbreak, nearly all monkeypox cases in people outside of Africa were linked to international travel to countries where the disease commonly occurs, or through imported animals. 

In May 2022, several clusters of monkeypox were reported in countries that don't normally report human monkeypox cases, including the United States.  On Friday, August 26, the Maryland Department of Health published a monkeypox data dashboard.  

As of September 22, we are offering vaccination to an expanded group of eligible residents.  In addition to those with a confirmed or possible recent exposure to the MPX virus, the County now is offering vaccinations to the following:

  • Persons of any gender or sexual orientation, with multiple or unknown sexual partners.
  • Priority will be given to those considered higher risk, including gay, bisexual, and other men who have sex with men, as well as immunocompromised individuals.
Those individuals who preregister and meet the eligibility guidelines will be contacted to schedule a vaccination appointment.  Those who have already preregistered and now meet the expanded eligibility will be contatcted and do not need to pregister again.

PRE-REGISTRATION FOR MONKEYPOX / MPX VACCINATION

Montgomery County has developed a pre-registration survey to identify County residents who are interested in receiving a Monkeypox / MPX vaccination.

Monkeypox is not a sexually transmitted infection (STI)  but is sexually associated.  Anyone can get Monkeypox/MPX, but with a limited vaccine supply, our priority is to protect those who may have already been exposed.

Our strategy (and pre-registration) will evolve as we learn more about who most urgently needs protection from Monkeypox/MPX.

Appointments are based on eligibility and vaccine supply and are not guaranteed.

It is not necessary to call the Department to check on the status of your appointment.


Where can a person in a high-risk group get vaccinated in Montgomery County?

Montgomery County has developed a pre-registration survey to identify County residents who are interested in receiving a monkeypox vaccination.

  • Persons of any gender or sexual orientation, with multiple or unknown sexual partners.

Those individuals who preregister and meet the eligibility guidelines will be contacted to schedule a vaccination appointment.  Those who have already preregistered and now meet the expanded eligibility will be contatcted and do not need to pregister again.Anyone can get monkeypox, but with a limited vaccine supply, our priority is to protect those who may have already been exposed. Our strategy (and pre-registration) will evolve as we learn more about who most urgently needs protection from monkeypox. Appointments are based on eligibility and vaccine supply and are not guaranteed. To pre-register for the vaccine see the preregistration links above. Pre-registration is available in multiple languages.

Where can I call to get information about monkeypox and vaccines in Montgomery County?

Because of high phone call volume, the easiest way to get an answer to your questions is by emailing MPXinfo@MontgomeryCountyMD.gov. You will receive a response within one business day. If you need to speak with someone on the phone, or require assistance with the vaccine pre-registration survey, please call 240-777-2982.

I pre-registered for the monkeypox vaccine. Is there a timeframe when I might get vaccinated? Do you anticipate everyone who has pre-registered will eventually receive the vaccine?

The County is committed to vaccinating all pre-registrants who meet criteria for vaccination. However, at this time, we unfortunately are unable to provide a timeline as to when we will be able to vaccinate all pre-registrants. This is dependent on vaccine availability from the Maryland Department of Health. The County will continue to provide regular updates to those pre-registered.

I have submitted the pre-registration form and I did not receive any response.

If you submitted a pre-registration and did not receive an email response, please email MPXinfo@MontgomeryCountyMD.gov and you will receive a response within one business day.

Is the County using intradermal vaccination to increase vaccine availability?

Effective Wednesday, August 24, the County is following revised federal and state guidance to transition from a two-dose subcutaneous (in the fat layer under the skin) regimen of JYNNEOS (given 28 days apart), to a smaller dose of JYNNEOS given intradermally (under the top layer of skin) in two doses, also 28 days apart.

When will private healthcare providers, pharmacies or others be authorized to offer this vaccine?

We believe that private providers will eventually have access to vaccine as national supply increases. There is no timeline for rollout of vaccine to private providers in Montgomery County or elsewhere in Maryland.

How will the personal information collected on the pre-registration form be used in the future?

The information is used by public health services is used to help us determine who is highest risk, and how much vaccine is needed. This information is considered confidential personal health information and is held compliance with HIPAA.

If someone received a first dose of the Jynneos vaccine and is then infected by monkeypox, are their symptoms lessened? If I get monkeypox between my first dose of the vaccine and second, should I still get the second dose?

Having the first dose will reduce the extent of infection and how bad symptoms are; for the average person there is no benefit to getting a second vaccine.

If you have had a smallpox vaccine when you were younger, do you have any protection from monkey pox virus?

We don’t know the answer to that question. There is probably a small degree of protection but not sufficient to prevent disease.

What if someone starts developing early symptoms while waiting for the vaccine, or finds out that they were recently exposed, would they get priority for vaccinations? How do they update their current request for the vaccine?

Montgomery County is prioritizing vaccination for people without symptoms who have been exposed to monkeypox, as vaccination 4-14 days after exposure can lessen symptoms and prevent illness. At this time, vaccination is not recommended for individuals experiencing symptoms consistent with monkeypox infection. If an individual is experiencing symptoms consistent with monkeypox infection or has had a confirmed case of monkeypox, they are no longer eligible for vaccination as the vaccine is not believed to have any additional benefits. If you believe that you may have monkeypox, we encourage you to contact either your primary care physician or one of the County’s emergency or urgent care centers for testing. For additional information concerning vaccination in special populations, please refer to the CDC.

To update a request for vaccination, email MPXinfo@montgomerycountymd.gov and let us know of any changes to the original registration. Individuals may also let us know if they are no longer interested in receiving a vaccine from Montgomery County.

If spread continues, will there be a consideration to offer vaccine to front line health care providers? They were prioritized for COVID-19 vaccination.

Currently, vaccination is being offered to health care providers who have been exposed. As we receive more supply, healthcare providers who are likely to be exposed to MPX may receive pre-exposure prophylaxis vaccination.
