There are Health care workers are beginning to distribute vaccines for the coronavirus.

WUSF and Health News Florida are answering your questions about the vaccines for the coronavirus.

A Vaccine for the Coronavirus has arrived and some Florida residents are among the first to get it.

WUSF and Health News Florida are reporting on each step of the process and we've been asking you for your questions. Were posting answers to those questions below.

Please share your questions on our form at the bottom of the story. If you're willing, a reporter may contact you.

Here are answers to some of the questions we've already received:


There are different companies producing coronavirus vaccines. Will all of them require people to get two doses? And do they need two doses of the same vaccine? How will people avoid getting two different vaccines?

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases.

The two current vaccines each require 2 doses. Other vaccines are being studied; one of them is a single dose vaccine. You do need to have two doses of the same vaccine. Ideally you should visit the same health practitioner who will be keeping a record of who is vaccinated with which vaccine.

EMS is supposed to be tier 1, but with hospitals getting the distributions is there a method to coordinate vaccinations for non-hospital-based EMS providers (fire, nonprofit, municipal owned)?

From Meedan's Digital Health Lab's learnaboutcovid19.org

A: The prioritization of initial COVID-19 vaccinations varies widely from location to location, with decisions being made at the federal, state, county and facility level. Emergency medical services (EMS) personnel are often included among the groups receiving the highest priority for the first shipments of the COVID-19 vaccine. Since the initial supply is not sufficient to vaccinate everyone within the highest priority groups, however, difficult decisions are being made about who is to receive the COVID-19 vaccines first. Some places are choosing to include EMS personnel outside of hospitals, such as in the fire department, in the first wave of COVID-19 vaccinations. Other places are distributing their first shipments of the COVID-19 vaccine straight to hospitals first. Read more here.

I am a 68-year-old snowbird that lives in Florida from November to April. However I am a Pennsylvania resident. Will I be able to receive a vaccination in Florida when it is available for elderly people?

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases:

The short answer is yes. You should be able to get the vaccine in Florida when it is available. But be mindful that you have to get 2 doses separated by 3 weeks and it has to be the same vaccine (i.e. Pfizer or Moderna). It would be most advisable for you to go back to the same provider because the records there will be the clearest and there will be no confusion. If you get the first vaccine in Florida, stay there for 3 weeks to get the second vaccine there as well.

I am 65 and live in a 55-plus community. When do you feel I can realistically expect to be able to get the vaccine?

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases:

The determining factor will be your age, not your community. You’ll be in the second or third group to receive a vaccine, likely by sometime this spring. We know healthcare providers are first, and then residents of long-term care facilities. We are waiting on advice from the CDC Advisory committee on who should go next -- essential workers, or people who are 65 or older.


[What are the] side effects [from the vaccines] for people with underlying health issues. Do they even know?

From Dr. William Moss, executive director of the International Vaccine Access Center:

Both [Pfizer and Moderna vaccines] use messenger RNA technology, a really novel vaccine platform. ...There still remain many questions to be answered as we go forward. At this juncture, we're only going to know about short-term side effects, but we need to know whether there are any potential rare, long-term side effects. Short-term side effects that we know of now appear in about 5% to 15% of participants. They include inflammation, soreness at the injection site, a low-grade fever, headaches, muscle aches and fatigue. These can last from 12 to 36 hours after vaccination.

What is the wait time after you get a PREVNAR13 vaccine before can get Covid vaccine?

From Beverly E. Sha, MD, of Rush University Medical Center's Division of Infectious Diseases.

Many clinical trials delayed vaccinations other than the flu shot for 30 days before or after a COVID-19 vaccine. This is to make it easier to assess side effects of the COVID-19 vaccine and was not due to concerns about safety or efficacy. In general inactivated vaccines, which Prevnar13 and the COVID-19 vaccines are, can be given at any time interval to each other, but it may be prudent to separate the doses by several weeks.

Can I get or spread COVID-19 from the vaccine?

From Side Effects Public Media:

No. The COVID-19 vaccine doses developed by Pfizer-BioNTech and Moderna ... has been in development for about three decades, but is only now being used for COVID-19. According to the CDC, mRNA vaccines teach your cells how to make a protein – or even just a piece of a protein – that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects you from getting infected if the real virus enters our bodies.


I have had hives all over my face and body and puffy lips from shellfish. Should I take Benadryl before the COVID vaccination?

From SideEffects Public Media

If you’ve had allergic reactions to vaccines in the past, you should talk to your primary care provider about the vaccine. People who have had severe allergic reactions may need to be monitored after receiving the vaccine. Polyethylene glycol has been pointed to as what has triggered some anaphylaxis.

The most common allergic reaction — especially in flu shots — are in people with egg allergies. The most common flu vaccines are developed with egg-based technology, but the FDA and CDC said common food allergies and medicines shouldn’t prevent most people from receiving the vaccine.

Is it safe for patients with autoimmune disease who take immunosuppressive medications to be vaccinated against COVID? Is it effective?

From Dr. William Moss, executive director of the International Vaccine Access Center:

There's no doubt that we're going to have to look very carefully at data on both the safety and efficacy because that too can be impaired in immunocompromised individuals. The vaccines that are typically not recommended routinely for severely immunocompromised individuals are what we call attenuated viral vaccines, where we take the natural virus and make it weaker. And this is a very old way of making vaccines. But for example, our measles, mumps, and rubella vaccines are attenuated viral vaccines. None of the front runners for COVID-19 or SARS-CoV-2 are that type of vaccine. So I don't anticipate problems with safety ... but that will need to be studied going forward.

Should organ (liver) transplant recipients who are taking anti-rejection medications (Prograf/Tacrolimus) be vaccinated for COVID-19?

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases:

The short answer is yes. Although this population hasn't been studied, we don’t think there is any chance of harm. It may be that the immune response is somewhat blunted, but it could do some good. The CDC advisory committee said it probably won’t hurt but it might help.

I am a healthy 77 year old man. If I get the vaccine, do I have to keep away from my 50 year old son, who received a kidney transplant over 20 years ago? He has to take immunosuppressant drugs daily. If so, for how long? Can he also take the vaccine?

From Beverly E. Sha, MD, of Rush University Medical Center's Division of Infectious Diseases.

None of the COVID-19 vaccines contain any live virus and thus recipients pose no risk to their contacts by receiving these vaccines.

My husband is 83 and I am 87. We both have chronic obstructive pulmonary disease (COPD) and I have contrast dye reaction. Should I take benadryl before getting the vaccine?

From Beverly E. Sha, MD, of Rush University Medical Center's Division of Infectious Diseases.

Per CDC, "all people who get a COVID-19 vaccine should be monitored on site. People who have had severe allergic reactions or who have had any type of immediate allergic reaction to a vaccine or injectable therapy should be monitored for at least 30 minutes after getting the vaccine. All other people should be monitored for at least 15 minutes after getting the vaccine." The benefit of pre-medicating with anti-histamines is unclear. Benadryl or cetirizine/loratidine/fexofenadine, which are all over the counter anti-histamines, should not interfere with the response to the vaccine. We would not expect there to be cross-allergenicity between contrast dye and either the Pfizer or Moderna vaccines so pre-medicating is likely unnecessary.

Do any of the manufacturers know if their vaccine is safe for people with HIV?

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases:

It probably won't hurt, but it could help. The second vaccine in line -- the Moderna vaccine -- included a small study of people with HIV infection and we expect to see that data shortly. But in the meantime, if people with HIV are offered the Pfizer vaccine they should take it.

I am a health care worker. I will be 62 years old next month. I have intrinsic asthma maybe twice a year. Can I/should I prep for the vaccine with just Benadryl? I have taken the influenza vaccine for the last 2 years without issue or prep.

From William Schaffner MD, medical director of the National Foundation for Infectious Diseases:

No preparation is necessary for someone with asthma. That person should have the same sort of response of any 62-year-old without asthma.


From Side Effects Public Media:

No. Vaccine providers will be able to bill insurance for a fee to administer the vaccine, but will not be able to charge you. They can seek reimbursement for uninsured patients from the Health Resources and Services Administration’s Provider Relief Fund.


From Meedan's Digital Health Lab's learnaboutcovid19.org, a global team of public health experts

None of the three leading vaccines manufacturers (Pfizer, Moderna, and AstraZeneca) has reported data ... on knowingly pregnant or breastfeeding individuals. As a result, we have a limited understanding of how effective the three leading vaccines are for pregnant and breastfeeding people, and if there are risks specific to them.

Before more data is available, it is best for pregnant and breastfeeding individuals to speak with their doctors about the best way to proceed. While it is unlikely that a doctor would recommend a pregnant or breastfeeding person get vaccinated before more data is available, every risk profile is different and is worth discussing with a care provider.


What responsibility does an employer have to all its employees when an employee tests COVID positive? Aren’t they obligated to inform everyone? No employer can possibly know all the employees the infected employee came in contact with!

From Zack Flood, an associate attorney specializing in labor and employment law, and Bob Simandl, chair of the Labor and Employment Group, both at the Milwaukee-based law firm von Briesen & Roper:

Zack Flood: There is a patchwork of state and local guidance across the country with regards to employer responsibilities. The most important thing is the general duty under federal Occupational Health and Safety Administration laws to create and maintain a safe workplace. The employer's responsibility to other employees when they find out that they have a positive test is first to make sure that person is not coming into work, because that is going to create a threat. But also communicating to the rest of the workforce that there has been a positive test, but not disclosing the identity of that employee. The identity of the individual must be kept confidential.

Bob Simandl: The employer should already have a policy that addresses what its role will be as it relates to an employee testing positive and in communicating with fellow employees about the risk and ways to remain safe. The overarching responsibility for the employer is to provide a safe workplace and to keep employees informed about those policies. The employer needs to communicate with employees where the exposure took place and how they are working with authorities to safeguard employees and families. Ultimately there has to be a post-mortem done on how the policy worked.
