Additional Information


  • In December 2020, pharmaceutical companies Pfizer and Moderna were granted Emergency Use Authorizations (EUAs) by the Federal Drug Administration (FDA) for COVID-19 vaccines.
  • This means the vaccine has been tested and is considered safe and effective for the general public to take.

How do they work?

  • Both the Pfizer and Moderna vaccines are known as mRNA vaccines. 
  • mRNA vaccines help our body develop immunity against COVID-19. Immunity means that your body will quickly recognize the virus that causes COVID-19 and will protect you from getting sick. 
    • mRNA vaccines do not change your DNA 
    • mRNA vaccines do not cause disease
    • mRNA vaccines are not weakened COVID19 virus
  • The vaccines require 2 separate doses to be fully protected from COVID-19
    • For the Pfizer vaccine, the doses are 21 days apart.
    • For the Moderna vaccine, the doses are 28 days apart.

What are the differences between the Moderna Vaccine and the Pfizer Vaccine?

Frequently Asked Questions About the COVID-19 Vaccines

The Maryland Health Department has created a frequently asked questions website that we encourage residents to visit for additional information. Some of the most frequently asked questions we're received are directly answered below. Check back frequently for updates! 

COVID-19 vaccines will not give you COVID-19 

  • There are several different types of vaccines in development, however, none of the COVID-19 vaccines available or currently in development in the United States use the live virus that causes COVID-19. The goal for each of these vaccines is to teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. These symptoms are normal and are a sign that the body is building immunity.  

People who have been infected with COVID-19 will still benefit from getting the COVID-19 vaccine 

  • At this time, we do not know how long someone is protected from getting sick again after recovering from COVID-19. The immunity someone gains from having an infection, called natural immunity, varies from person to person. Some early evidence suggests natural immunity may not last very long. We don’t know exactly how long immunity produced by a vaccination lasts but there is strong evidence to support that immunity due to vaccination lasts longer than natural immunity. The vaccine provides longer and stronger immunity 

Getting vaccinated can help prevent getting sick with COVID-19 

  • While many people with COVID-19 have only a mild illness, others may develop more severe illness or even death. There is no way to know how COVID-19 will affect you, even if you are not at increased risk of severe complications. If you get sick, you also may spread the disease to friends, family, and others around you while you are sick. COVID-19 vaccination helps protect you by creating an antibody response without having to experience sickness. 

Until we’ve reached herd immunity, you still need to wear a mask, avoid large indoor gatherings, and physically distant even after getting the vaccine.  

  • Even though the vaccine is between 94 and 95% effective at reducing severe illness, about 1 in 20 people who receive it will not become immune.  At this time, it is also unclear whether having immunity protects you from carrying the virus and passing it to others. Until a significant portion of the population becomes immune (referred to as “herd immunity”), the precautions must be carefully followed. This will likely take months or even years depending on vaccine uptake. 

Receiving an mRNA vaccine will not alter your DNA 

  • mRNA stands for messenger ribonucleic acid and can most easily be described as instructions for how to make a protein or even just a piece of a protein. mRNA is not able to alter or modify a person’s genetic makeup (DNA). The mRNA from a COVID-19 vaccine never enters the nucleus of the cell, which is where our DNA is kept. This means the mRNA does not affect or interact with our DNA in any way. Instead, COVID-19 vaccines that use mRNA work with the body’s natural defenses to safely develop protection (immunity) to disease.

Key Principles for Allocation in Baltimore City

During the early weeks of Maryland’s vaccination program, vaccine supply is expected to be limited. With a limited supply of vaccines, healthcare workers, first responders, LTCF residents and people at significantly higher risk of severe COVID-19 disease will need to be sub-prioritized. Multiple factors, informed by the National Academies of Science, Engineering and Medicine’s Framework for Equitable Allocation of Vaccine, have been considered for sub-prioritization, such as, but not limited to:  

  • Risk of acquiring infection: People have higher priority if work or live in an environment with a higher risk of transmission due to a circulating virus.
  • Risk of severe morbidity and mortality: People with a high risk of severe outcomes (hospitalization, mechanical ventilation) and death from SARS-COV-2 infection. People who are older or have chronic medical conditions are at higher risk of severe outcomes.
  • Risk of negative societal impact: Inability to maintain services to preserve the functioning of society (i.e. providing health care, emergency response, public safety).
  • Risk of transmitting the virus to others (at work or at home): People have higher priority if there is a higher likelihood of them transmitting the disease to others.  


In the setting of limited vaccine supply, BCHD is utilizing ethical principles as outlined by ACIP to guide sub-prioritization decision making. These ethical principles are: 

  • Maximize benefits and minimize harm: Allocation of vaccine to groups or individuals should maximize the benefits of vaccination – reduction in hospitalization and death and reduction in risk of SARS-COV-2 infection, the virus that causes COVID-19. Preserving the functioning of society and minimizing harm to certain individuals and groups should also be considered. 
  • Promotion of justice: All individuals and groups should have equal opportunity to receive the COVID-19 vaccine, within priority populations during constrained supply and when the vaccine becomes available to the general population. 
  • Mitigation of health inequity: Certain groups have been disproportionately impacted by COVID-19 with an increased risk of infection, hospitalization, and death. Socioeconomic marginalization, age distribution, occupation/employment-type, limited access to healthcare are intersecting determinants of health that have resulted in disparate outcomes in hospitalization and death among older adult, Latino/Hispanic, and African American Baltimore City residents. Prioritization of vaccine allocation for certain groups should aim to reduce health disparities and not widen or create disparities. 

BCHD’s sub-prioritization decision making is grounded in the promotion of transparency. Transparency is essential to building and maintaining community trust. Outreach to priority groups throughout the vaccination program is critical. BCHD is engaging community members, collaborating with City government agencies, local health organizations, and health systems to inform focused outreach to priority groups. BCHD is developing a public-facing COVID-19 vaccination data dashboard to show vaccine administration by age, race/ethnicity, neighborhood, and other demographics, and to help inform outreach to priority groups

Priority Groups and Tiers

Following is the sub-prioritization for allocating COVID-19 vaccine in Priority Group 1A, Priority Group 1B, and Priority Group 1C.  Settings and roles within a priority group have equal priority. Vaccine allocation within Priority Groups is tiered due to the initial limited vaccine supply. List order does not imply ranking within a tier. Sub-prioritization was developed in concert with Health Officers from Maryland jurisdictions for near consistent prioritization across the State. Baltimore City Health Department is developing tailored sub-prioritization accounting for specific population factors and priorities for Baltimore City.
