Cayman Islands Government

Last Updated: February 16, 2022

This page seeks to answer frequently asked questions about the Booster Programme introduced by the Cayman Islands Government in October 2021. 

Here are some commonly asked questions about the COVID-19 Booster:

  • What is a booster?
  • Do I need a booster?
  • Am I fully vaccinated without a booster?
  • Is the booster free?
  • Who is eligible to get a booster?
  • How do I get a booster?
  • Can I get my booster vaccine at home?


What is a booster?

A booster is a vaccine shot meant to increase levels of the response from our immune system after coverage from previous vaccination has started to wane

Do I need a booster?

COVID-19 vaccines are very effective in lowering the risk of severe disease, hospitalisation, and death. Recent studies have found that two- dose protection may wear off over time. Boosters extend the immunity offered by vaccination.

Am I fully vaccinated without a booster?

Current definition of “fully vaccinated” refers to 2 doses (i.e. completion of a full course of vaccine requiring 2 doses ). It is not unlikely that at some point the definition might change to incorporate the booster into it.


Is the booster free?

Yes, the booster is free. You do not need to pay, have ID, or have health insurance to get a booster.

If I need a booster shot, does that mean that the vaccines aren’t working?

No. COVID-19 vaccines are working well to prevent severe illness, hospitalization, and death, even against newly discovered variants. However, public health experts are starting to see reduced protection, especially among immunocompromised persons after a certain length of time, especially when it comes to be infected.


Who is eligible to get a booster?

Persons who are eighteen years and over and receive their second dose of vaccine more than three months ago.

Can I mix and match my booster dose?

Boosters can be done either with the same type of vaccine used for the primary vaccination (homologous booster) or using a different type of vaccine (heterologous booster). Antibody levels were higher when a mRNA (messenger RNA) vaccine was used as a booster. The Pfizer BioNTech vaccine offered by the Public Health department is a mRNA vaccine.

Do I need to be a Cayman Islands resident to get a booster? What if I lived somewhere else when I got my initial COVID-19 vaccine doses?

You can get a booster if you live, work or study in the Cayman Islands. Your previous vaccination records must be presented.


How do I get a booster?

If you have completed two-dose vaccination course more than three months ago and have not had a COVID-19 infection for at least 4 weeks, you can receive the booster at any HSA Public Health clinic. The main vaccination clinic is located at 131 MacLendon Drive, next to DHL.

Can I just walk-in or do I need to book an appointment?

No appointment is necessary.

Can I get my booster vaccine at home?

Yes. If you or a person in your care is housebound, a vaccination can be requested by calling your nearest District Health Centre.

Should people expect to get sick after the third dose?

Current data indicates that side effects following the additional dose are similar to those after the second dose. Common side effects are generally mild such as localized pain, redness or swelling at the injection site, and fatigue, headache, and low-grade fever. Serious adverse events are rare.

Can I get a flu vaccination at the same time as my COVID-19 booster?

Yes. You can get a COVID-19 vaccine and other vaccinations like a flu or shingles vaccine at the same time or close together.

How much time should there be between my last vaccination and the booster?

There must be at least 3 months between your last vaccination and the booster vaccination. 


I'm pregnant. Should I get a booster vaccination now?

You can still get the booster vaccination if you are pregnant.

As a pregnant woman, you do have a higher risk of becoming seriously ill from COVID-19. This can have consequences for both mother and child. 

Speak to your doctor if you are unsure 

What do I need to bring to the COVID-19 clinic?

  • Vaccination card or digital vaccination certificate showing the date for the second dose
  • Government-issued photo identification showing date of birth
  • Facemasks (please bring your own)


Does the Booster cause Side Effects?

The COVID-19 vaccines have been proven to be safe and effective against COVID-19. When you get the vaccine, as with any vaccine, you may experience some mild side effects. Learn more here. 

which vaccine is used for the booster?

The Pfizer BioNT vaccine is administered as the COVID-19 booster vaccine in the Cayman Islands.


Can I get the Pfizer/BioNTech booster even though my first and second vaccine are not Pfizer?

Yes. It does not matter which type of vaccine was received for the first and second vaccination. 


Is it safe to get the booster vaccination with a Different brand of vaccine?

Research indicates that there is no difference in the effectiveness or side-effects after receiving a booster vaccination with a different brand than the first or second dose.

I had one Vaccination, and then I had COVID-19. Should i still get vaccinated?

Yes. Even if you have had COVID-19 after your first vaccination, you should still get your second vaccination. After that, you need to wait at least 3 months before getting the booster.
