Frequently Asked Questions

Delaware

The vaccine is available from Primary Care Providers, pharmacies, Federally Qualified Health Centers, hospital systems, events coordinated by Public Health or its partner Curative Inc, and community-based organizations that are partnering with vaccine providers. The best source of information about availability is https://coronavirus.delaware.gov/vaccine/where-can-i-get-my-vaccine/.

Do I need an appointment?

While some places require an appointment, more and more are accepting walk-ins such as Division of Public Health clinics. A list of clinics and other community locations and Federally Qualified Health Centers accepting walk-ins can be found at https://coronavirus.delaware.gov/vaccine/where-can-i-get-my-vaccine/.

Do I have a say in which vaccine I get?

While youth under age 18 are only eligible for the Pfizer vaccine at this time, the Division of Public Health recommends that all other adults take any of the vaccines that are available. However, we understand that you may want to compare vaccines. You can see a comparison chart here.

Vaccine provided at each site is dependent upon supply received. Choice of vaccine is not available as certain locations are only distributing one vaccine. If you have a preference in vaccine, you can contact the location you are receiving your vaccine beforehand to discuss which vaccine is available. When you receive the vaccine, you will receive a card that states which vaccine was provided, including company name, lot number, date received and location.

Development/Safety/Effectiveness

What is a vaccine?

A vaccine is a substance that teaches your body to recognize that a foreign invader such as a virus or bacteria has entered the body. Once the body recognizes the invader, the body’s immune system is activated, and fighter cells and proteins fight the virus or the bacteria. A vaccine is much like a decoy, it tricks the body into thinking it is the virus, but it does not actually cause the disease. It helps your body fend off the virus.

How effective is the vaccine?

All three vaccines, Pfizer, Moderna and Johnson&Johnson are highly effective at preventing COVID-19 related death and hospitalization. Pfizer-BioNTech and Moderna are 95% effective against all forms of COVID infections, and the J&J/Janssen vaccine is 74% effective. In comparison, the annual flu vaccine is typically between 40% and 60% effective in preventing influenza. It is unknown how long the COVID vaccine’s effectiveness will last, so an annual vaccine (much like the flu) may be required.

How was the COVID vaccine developed so quickly?

The vaccine was developed in a much shorter period of time, due to the obvious need to address the public health threat the pandemic posed to the nation. A shorter development and review time does not mean the vaccine is unsafe.

Scientists had a head start: COVID-19 vaccines are built on years of work to develop vaccines for similar viruses. All available vaccines use technologies that researchers have been studying and working with for decades – which included technology advances to map the virus’s DNA. A lot of the groundwork was already laid during the search for vaccines to fight Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).

The Coronavirus that causes COVID-19 is part of a broader family of coronaviruses – and related to SARS and MERS. Researches have been engaged in searching for vaccines for those closely related viruses for several years, so they were not starting from scratch with COVID, according to the Mayo Clinic. Researchers also benefited from a budget of $4.5 billion from the US government, which gave vaccine manufacturers all the resources they needed to accelerate their process.

Additionally, the clinical trial process was accelerated by enrolling more people in trials to enhance rapid data collection and earlier analysis of safety data for demographically diverse populations. This also sped up the FDA review process as they have been monitoring the data all along.

And, delivery/distribution time was shortened by allowing manufacturing to occur at the same time as instead of after, vaccine approval.

Since the vaccine was developed quickly, how do I know it’s safe?

Over 250 million doses of the vaccine have been given in the U.S. since December 2020. According to the CDC, COVID-19 vaccines are safe and effective!

All vaccines are rigorously tested for safety and effectiveness.

Are there known side effects to the vaccine?

The side effects have been minimal and temporary for all three vaccines, generally going away within 24 hours. Side effects are normal signs that your body is building protection. The CDC reports it has seen no trends of serious or long-term side effects. To report serious side effects, call 1-800-822-7967 or vaers.hhs.gov/reportevent .

Rare Severe Allergic Reactions: In some rare cases, severe allergic reactions have occurred within minutes to an hour of receiving both the Pfizer BioNTech and the Moderna vaccines. Signs of a severe allergic reaction include trouble breathing, swelling of face and throat, rapid heartbeat, dizziness and a rash that covers the whole body. If you experience any of these symptoms call 9-1-1 immediately or go to the nearest hospital.

Are there any individuals who should not get the vaccine?

You should not get the COVID-19 vaccine:
