A: The easiest and fastest way to make an appointment is through MyLVHN. If you do not have a MyLVHN account, you also can make an appointment on this website.
People who do not have access to technology can call the LVHN COVID-19 Vaccine Hotline at 833-584-6283 (833-LVHN-CVD) to schedule their appointment. Please note that call volumes are high and you may have to wait on hold. The COVID-19 Vaccine Hotline hours of operation are Monday-Friday 8:30 a.m.-5:30 p.m. or Saturday-Sunday 9 a.m.-5 p.m. MyLVHN will be your fastest and easiest way to schedule.
A: Currently, only the Pfizer/BioNTech vaccine has Emergency Use Authorization for people age 16-17. To ensure that your child receives the right vaccine, appointments for people age 16 and 17 are available at select locations. Appointments must be made by a guardian and a guardian must be present at the time of vaccination.
A: Appointments are required and we will not accept walk-ins. You can schedule your appointment through MyLVHN or by calling the LVHN COVID-19 Vaccine Hotline at 833-584-6283 (833-LVHN-CVD). The COVID-19 Vaccine Hotline hours of operation are Monday-Friday 8:30 a.m.-5:30 p.m. or Saturday-Sunday 9 a.m.-5 p.m.
You can cancel your appointment through MyLVHN or by calling the LVHN COVID-19 Vaccine Hotline 833-584-6283 (833-LVHN-CVD). The COVID-19 Vaccine Hotline hours of operation are Monday-Friday 8:30 a.m.-5:30 p.m. or Saturday-Sunday 9 a.m.-5 p.m.
The CDC recommends that people receive the second dose of COVID-19 vaccine 42 days after the first dose. If that is not possible, the CDC says people should receive the second dose as close as possible to the 42-day mark. There is no data to suggest that booster doses provided after 42 days are not effective.
A: No, you are not able to transfer appointments to others.
A: LVHN is not providing second doses for people who received their first dose elsewhere. The State of Pennsylvania records the location of your first dose and will send the second dose to the same location.
A: No, we recommend that everyone schedule their vaccine appointment as soon as possible. The more people who receive the vaccine, the closer our community gets to herd immunity.
A: Appointments may be scheduled by calling 833-584-6283 (833-LVHN-CVD). The COVID-19 Vaccine Hotline hours of operation are Monday-Friday 8:30 a.m.-5:30 p.m. or Saturday-Sunday 9 a.m.-5 p.m.
A: Patients cannot choose which vaccine they will receive at this time. Due to limited supply, vaccines are given based on inventory at the time of your appointment. While you will not be able to choose which vaccine you will receive, any vaccine that has been granted EUA by the FDA has been proven to be both safe and effective.
A: Currently, the state of Pennsylvania is sending all shipments of Johnson & Johnson vaccine to intermediate units and retail pharmacies as a part of a thoughtful plan to vaccinate prekindergarten-12 educators and staff as well as early childhood education workers. Prekindergarten-12 educators and staff can receive a Moderna or Pfizer vaccine at LVHN.
A: There are no preexisting conditions that are contraindications for the COVID-19 vaccine. (Contraindication: A symptom or condition that makes use of a drug, like the vaccine, risky). If you have questions about a medical condition or allergy, speak with your primary care provider.
There are some reasons to carefully plan when you have your COVID-19 vaccine:
A: Yes. While people who have tested positive for COVID-19 do produce antibodies, the antibody levels and how long they last are not known. Due to the severe health risks associated with COVID-19, and the fact that re-infection with COVID-19 is possible, you are advised to get a COVID-19 vaccine even if you have been sick with COVID-19 previously. At this time, experts 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, and the evidence suggests natural immunity may not last very long in some people.
A: Both Pfizer/BioNTech’s and Moderna’s vaccines are mRNA vaccines. This means they are made from genetic material that provides your body with the code it needs to create spike proteins (not the virus) and build immunity. AstraZeneca’s and Johnson & Johnson’s are non-replicating virus-vectored vaccines. None of these vaccines are live vaccines.
A: The American College of Obstetricians and Gynecologists (ACOG), Society for Maternal-Fetal Medicine (SMFM) and American Society for Reproductive Medicine (ASRM) all recommend that these patients be offered the COVID-19 vaccine.
These societies also recommend the vaccine be offered to patients undergoing fertility treatment based on Advisory Committee on Immunization Practices (ACIP) eligibility criteria. Since the vaccine is not a live virus, there is no reason to delay pregnancy attempts because of vaccination or to defer treatment until the second dose has been administered.
A: Pfizer has reported that some Phase III clinical trial participants experienced mild-to-moderate side effects with its investigational COVID-19 vaccine candidate. Scientists anticipate that the shots may cause mild flu-like side effects – including sore arm, muscle aches and fever. These mild side effects are more common after the second dose. Read how LVHN front-line colleagues felt after their first dose and after their second dose of vaccine.
A: Any vaccine that has received Emergency Use Authorization from the U.S. Food and Drug Administration has been proven effective and safe. This includes the Johnson & Johnson vaccine.
A: Pfizer/BioNTech’s and Moderna’s vaccines use novel messenger-RNA, or mRNA, technology, which uses modified genetic material to cause the body to create a protein from the virus. The immune system then recognizes the protein as foreign and initiates an immune response.
For the Johnson & Johnson vaccine, researchers took DNA from the coronavirus and put it in a shell called an adenovirus. The adenovirus cannot replicate in your system or make you sick. It acts as a Trojan horse by entering your system like a virus would and then prompting your body to create antibodies.
A: There are a few things that make the Johnson & Johnson vaccine different than the Moderna and Pfizer vaccines. As noted above, there is a difference in the way this vaccine is made. Researchers took DNA from the coronavirus and put it in a shell called an adenovirus. The adenovirus cannot replicate in your system or make you sick. It acts as a Trojan horse by entering your system like a virus would and then prompting your body to create antibodies. Johnson & Johnson has decades of research on adenovirus vaccines. Other vaccines available that use this technology include the Ebola vaccine (also made by Johnson & Johnson), the HPV vaccine, the hepatitis B vaccine and even one of the influenza vaccines.
Unlike the Pfizer and Moderna vaccines, only one dose is required for the Johnson & Johnson vaccine. Pfizer and Moderna vaccines must be stored in freezers, while the Johnson & Johnson vaccine can be kept in a refrigerator for at least three months.
A: Current data shows that COVID-19 vaccines are effective at preventing severe disease. During the clinical trials, scientists compared how many people in the vaccinated group and the placebo group went on to develop the disease.
The companies will continue to test people in the studies for antibodies to the COVID-19 virus, which would include people who did not show any symptoms of infection. This allows researchers to get a better sense of whether the vaccines protect against not only getting sick (experiencing symptoms), but also against infection (becoming infected without experiencing symptoms).
A: No. These vaccines will not cause you to test positive on viral tests, which are used to see if you have a current infection. If your body develops an immune response, which is the goal of vaccination, you should test positive on antibody tests. Antibody tests indicate you had a previous infection or vaccination and that you may have some level of protection against the virus.
A: According to the Centers for Disease Control and Prevention (CDC), a vaccine stimulates your immune system to produce antibodies and cellular immunity to combat a specific disease, like it would if you were actually exposed to the disease. After getting vaccinated, you develop immunity to that disease without having to get the disease first. This is why vaccines are necessary — they prevent disease by letting you develop immunity in a safe and controlled way.
A: Both the Moderna and Pfizer/BioNTech vaccines require two doses. The different vaccine products are not interchangeable. The CDC recommends that people receive the second dose of COVID-19 vaccine 42 days after the first dose. If that is not possible, the CDC says people should receive the second dose as close as possible to the 42-day mark. There is no data to suggest that booster doses provided after 42 days are not effective. While vaccine supply is determined by the state of Pennsylvania, we are doing everything in our control to help you reach that target.
The Johnson & Johnson vaccine requires one dose.
A: These two COVID-19 vaccines are not completely effective unless you receive the second dose.
A: When you receive a COVID-19 vaccine, your immune system goes to work creating antibodies to protect itself from the coronavirus. The vaccine CANNOT cause a COVID-19 infection but can cause side effects, including pain at the injection site, tiredness, headache, muscle pain, chills, joint pain and fever. Pfizer has reported that some Phase III clinical trial participants experienced mild to moderate flu-like side effects, including sore arm, muscle aches and fever.
Ultimately, symptoms such as sore arms, muscle aches, fever and headaches mean that your immune system is responding to the vaccine and producing antibodies that will protect against future infection with coronavirus. Read how some of LVHN front-line colleagues felt after their second vaccination.
If you experience cough, sore throat, shortness of breath, or loss of taste or smell, stay home. Those symptoms are not known to be side effects associated with the vaccine. It may be difficult to distinguish between some side effects of the vaccine and symptoms of COVID-19 or other illnesses. When in doubt, speak to a provider virtually. You can view virtual care options at LVHN.org/VirtualCare.
A: A flu vaccine will not protect you from getting COVID-19, but it can help to prevent you from getting influenza (flu) at the same time as COVID-19. This can help keep you from having a more severe illness. While it’s not possible to say with certainty what will happen this winter, CDC believes it’s likely that flu viruses and the virus that causes COVID-19 will both spread during that time. You should encourage all of your friends and family to get flu shots.
A: Yes, we should all continue wearing face masks, practicing excellent hand hygiene and social distancing until enough vaccine is manufactured and distributed, until we know how long a vaccine will protect us, and until our community shows reduced levels of spread.
It is unclear at this point if the vaccine prevents people from becoming infected with COVID-19 or if it prevents feeling sick when infected. That means you could still transmit virus after you’ve received your shot.
A: In the short term, no. But if most people receive a COVID-19 vaccine, the pandemic could drastically shrink. This means we are one giant step closer to getting our lives back to normal provided as many people as possible get vaccinated as early as possible.
A: In an emergency, like a pandemic, the FDA can make a judgment that it is worth releasing something for use even without following the typical timeline for a new vaccine or drug. The administrative portions of the trial have been sped up. The scientific analysis of clinical trial participants remains the same for these and all other vaccines. If there’s evidence that strongly suggests that patients have benefited from the vaccine in clinical trials and that it is safe, the agency can issue an EUA to make it available. The FDA has issued EUAs many times previously in other situations. The EUA process is well established and is not newly created to address COVID-19 vaccine development. Three COVID-19 vaccines currently have Emergency Use Authorization – the Moderna vaccine, the Pfizer/BioNTech vaccine and the Johnson & Johnson vaccine.
A: The Johnson & Johnson vaccine does not use mRNA. Researchers took DNA from the coronavirus and put it in a shell called an adenovirus. The adenovirus cannot replicate in your system or make you sick. It acts as a Trojan horse by entering your system like a virus would and then prompting your body to create antibodies. Johnson & Johnson has decades of research on adenovirus vaccines. Other vaccines available that use this technology include the Ebola vaccine (also made by Johnson & Johnson), the HPV vaccine, the hepatitis B vaccine and even one of the influenza vaccines.
