COVID-19 Vaccines in the Cayman Islands

We know you might be thinking about the COVID-19 vaccine and what that means for you and your family. We also understand that some people may be concerned about getting vaccinated with a COVID-19 vaccine. It’s important to note that vaccination is not mandatory for anyone. This information has been compiled to give you all the important information you may need to know about the COVID-19 vaccination programme for the Cayman Islands.

Most people know that vaccines typically require years of research and testing before reaching the clinic. However, 2020 has been a year of unprecedented happenings and scientists have gone hard to work to help stop the pandemic. Although there has been a lot of momentum to develop a vaccine as quickly as possible, you should know that routine processes and procedures remain in place to ensure the safety of any vaccine that is authorized or approved for use. Safety is always a top priority.

Here you will find FAQs to see where you fit in when it comes to the roll-out of a COVID-19 vaccine. These may also address some of your concerns.

On 2nd December 2020, the United Kingdom became the first country in the world to approve the Pfizer/BioNTech SARS-CoV-2 vaccine, paving the way for mass vaccination. As a UK Overseas Territory (UKOT), the Cayman Islands received the first batch of these vaccines on 5th January 2021 and commenced the COVID-19 National Vaccination programme shortly thereafter.

I'm still unsure


Is there a vaccine against COVID-19?

Yes, the Pfizer/BioNTech vaccine is the first vaccine approved by the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA). This vaccine will be used in the Cayman Islands through assistance provided by the United Kingdom to the UKOTs.


How effective and safe is this COVID-19 vaccine?

The vaccine offers up to 95% protection against the SARS-CoV-2 virus. It is important to note that before a vaccine is shown to be safe and effective, numerous steps need to be achieved before mass distribution.

The safety and immunogenicity of the Pfizer and BioNTech COVID-19 vaccine have been evaluated in clinical trials in six countries: the USA, Germany, Brazil, Argentina, South Africa and Turkey.

The clinical trials looked at the safety and immunogenicity of the vaccine in different age groups and at different dose levels. Over 43,500 participants have taken part in the clinical trials of the Pfizer/BioNTech COVID-19 vaccine.

Half of the participants received the COVID-19 vaccine and the other half received a placebo vaccine. Results from phase three clinical trials suggest that the vaccine can prevent 95% of vaccinated adults from getting COVID-19 disease and that the vaccine works equally well in people in different age groups, races and ethnicities. The observed efficacy in adults over 65 years of age was over 94%.


Will I Get Side Effects With The COVID-19 Vaccine?

With the Pfizer/BioNTech vaccine, a number of people have got some local pain around the injection site. The most common other events were headache, muscle aches, chills, joint pain and a raised temperature. “More people experience side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that there may be some side effects after either dose, but even more so after the second dose.
With the AstraZeneca vaccine, mild pain and tenderness were common. Short lived symptoms of headache and tiredness, muscle aches, feeling generally unwell, a raised temperature and chills, and joint pain and nausea were also experienced.

Who Can Get The Pfizer/BioNTech COVID-19 Vaccine?

The vaccine has been trialled in adults and anyone over the age of 16 will be eligible. There may be some circumstances in which children may be given the vaccine, for example if they are in a medical high risk group.

Individuals with a history of anaphylaxis to food, an identified drug or vaccine, or an insect sting can receive any COVID-19 vaccine, as long as they are not known to be allergic to component (excipient) of the vaccine. The British Society for Allergy and Clinical Immunology (BSACI) has advised that individuals with a history of immediate onset-anaphylaxis to multiple classes of drugs or an unexplained anaphylaxis should not be vaccinated with the Pfizer/BioNTech vaccine.


When Can I Get The COVID-19 Vaccine?

The COVID-19 Vaccination Programme in the Cayman Island is rolling out in three stages.

Individuals who are within certain groups are invited to the 'flu clinic and Owen Roberts International Airport in Grand Cayman and other district clinics on certain days to receive their vaccinations.

The schedule, locations and roll out for the vaccine are available here.

As of 15th March persons over the age of 60+ can be vaccinated at any time during the published schedule.  As of 24th February, Stage Two Group C can also receive their vaccine along with all prior group at the relevant time.

View The Schedule

Click below to find out which stage and group you are in for the vaccination programme in the Cayman Islands.



The stages and sub-groups are also listed below:

Stage One

Group A

  • Individuals aged 70+
  • Residents and staff of institutional facilities
  • Healthcare workers and first responders
  • All frontline staff dealing with incoming travellers

Current evidence shows the biggest risk of death from COVID-19 is age, so those aged 70+ are a top priority followed by those who are on the frontlines.

Group B

  • Adults 60+ or with a relevant health status

Group C

  • Workers essential to Government continuity

Stage Two

Group A

  • Anyone aged 16-60 with relevant medical status. Please note: Anyone in Stage 2, Group A with a medical condition is required to provide a note from their doctor. Persons requiring a note from their HSA doctor are asked to request this by contacting the Flu Hotline flu@hsa.ky1-800-534-8600 or 925-6327.

Group B

  • Essential workers (supermarket workers, those working for the utilities, people working at gas stations, customer facing people working in retail, those working in hotels, restaurants and bars, those working for food delivery companies, security companies, cleaning companies, personal/touch services, caregivers and Civil Servants) who present a work ID to show proof of employer.
  • Teachers
  • School Employees

Group C

  • Those living at home with persons from stage one of the programme

Stage Three

  • Everyone 16+ who has not already received the vaccination. This will begin with persons aged 50+


Additional Notes

All persons must present photo identification to prove they are an ordinary and legal resident, for example a CI Driver’s license, CI Voters ID, CI Passport, Non-Caymanian passport showing approval to be on island for six months from arrival, Work Permit extension letter, Work Permit grant letter, job letter (from a local organisation), or Global Citizens (GCCP) Certificate.



Public Health continues to vaccinate our most vulnerable population, specifically those 70 and over. 

Caregivers of persons 70+ are eligible for the COVID vaccine in the continued effort to keep the most vulnerable safe. The vaccine is available for persons providing care for home bound elderly persons 

Caregivers and persons responsible for the elderly in their homes can contact the HSA’s Flu Hotline 1-800-534-8600 or 925-6327 to provide the following details: Caregivers full name, phone number, patient name, and date of birth.  Once a caregiver has been identified, those persons will be approved for the vaccination and name checked at the vaccination clinic. Please check the schedule for your designated vaccination time. 


Overseas University Students  

University students who will be attending institutions overseas may also get vaccinated on their assigned day and must present university ID. 


Second Dose

Persons who have received their first dose are reminded to get their second dose 21 days later or no longer than 12 weeks after the first dose.


Home Bound

Medical professionals will be visiting healthcare and institutional facilities to ensure that those who cannot visit clinics can opt to receive the vaccine.


How Will The COVID-19 Vaccine Be Administered?

The Pfizer/BioNTech COVID-19 vaccine will be administered by intramuscular (IM) injection, similar to the ‘flu shot.


How Can A Safe COVID-19 Vaccine Be Made So Quickly?

Although vaccine development typically takes many years, scientists had already begun research for coronavirus vaccines during previous outbreaks caused by related coronaviruses such as SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome). That earlier research provided a head start for rapid development of vaccines to protect against infection with the novel coronavirus SARS-CoV2, the virus that causes COVID-19.


They have also overlapped different stages of the process, such that manufacturing was already well underway whilst the clinical trials were still ongoing; additionally, information was provided to many regulators on a rolling basis, rather than all at once at the end of the trial periods.


Can Other Vaccines, Including Flu Vaccines, Be Administered At The Same Time As The COVID-19 Vaccines?

COVID- 19 vaccines should not be routinely offered at the same time as other vaccines. Scheduling of COVID-19 vaccine and other vaccines should ideally be separated by an interval of at least fourteen (14) days more so as not to incorrectly attribute potential adverse events rather than any potential for interaction. Public Health also recommends waiting a month for some vaccines, such as Hepatitis B.


Once I Get Vaccinated, Can I Still Get Sick?

It is possible you could still get sick as the vaccines are 95% effective, therefore there is a small chance that if you are exposed to COVID-19, you might get sick.

It is also possible to get sick with COVID-19 a few weeks after the vaccination if you have been exposed to the virus. It takes a few weeks to build an immune response after being vaccinated. So it's possible that someone could be infected with the virus that causes COVID-19 and get sick just before or just after vaccination. 


Can The COVID-19 Virus Still Be Transmitted From Someone Who Has Received The Vaccine But Remains Asymptomatic?

We believe that this might be possible i.e. someone might have had a proper course of the vaccine and be protected themselves, but still might be able to transmit the infection to someone else.  This is because the inside of the body is protected against an infection but the infection might still be able to survive in the upper airways.  However, a person who does not have symptoms is also not coughing and sneezing which very much reduces the possibility of transmission.  More information about this aspect will come out when the scientists have had more time to study the effects of vaccinations of large numbers of people.  The best thing to do to protect the community is to take the vaccine.


How Long Is The Duration Of Protection?

Published data from Pfizer says that short term efficacy between dose one and two is 52.4%. The UK’s Joint Committee on Vaccination and Immunisation has said that short-term efficacy from the first dose of the Pfizer-BioNTech vaccine is calculated at around 90%. Immunity provided by the Pfizer/BioNTech vaccine reaches its full effect seven days after the second dose. However, long term efficacy is unknown.

We will know how long the immunity produced by the vaccine lasts as more data is collected.

However, it is too early to know if whether this is a one-off injection or an annual one, like that for the ‘flu.


Will We Still Need To Wear Masks And Practice Physical Distancing Once Vaccinated Where These Are Mandated?

The wearing of masks and practising of physical distancing will be required until a large proportion of the population is vaccinated and we are sure the vaccine provides long-term protection. Herd immunity is achieved when a sufficient proportion of the population is made non-infectious through vaccination so that the likelihood of an infectious individual transmitting to a susceptible individual is very low. Frequent hand washing and respiratory etiquette are essential in stopping the spread.


I’ve received a full course of vaccination against COVID-19, do I still need to quarantine when I return from travel?

All returning passengers, regardless of having a full vaccination course, are required to undergo a 14 day quarantine for the purpose of surveillance by the Medical Officer of Health as required under the Control of COVID-19 (No.3) (Amendment) Regulations, 2021. The Premier has announced the Governments plans that once 90% of those over 60 years of age have been vaccinated in the Cayman Islands, the quarantine period may be reduced to 10 days, provided the traveller meets various conditions which include a full course of a COVID-19 vaccination which has been approved by the Chief Medical Officer. For more details of these conditions, please click here.

Although vaccines may protect people against COVID-19 disease and are likely to prevent death, it is likely still possible for vaccinated people to carry the virus in their throat, nose, airways and so transmit it to others. Additionally, vaccination may not give full protection to mutations of the original SARS-CoV-2 virus. The Ministry of Health recognises that some countries are relaxing requirements for people who have been vaccinated, but Cayman is fairly unique in that there is no known community spread. This means our regulations will be different to many surrounding countries.


Well what’s the point of taking the vaccine if I can still get COVID-19 and still transmit it?

The chances that you will get COVID-19 are greatly reduced if you take the vaccine, as the vaccine has been shown to be 95% effective in preventing the vaccinated person from becoming infected. The fewer people who get infected with COVID-19 the less the disease is able to spread. It is also worth noting that people who are vaccinated but still contract COVID-19 have much less severe effects from the disease.


Does The Cayman Islands Have A COVID-19 Vaccination Programme?

Yes, the vaccination programme is comprised of three vaccination stages in which healthcare and frontline workers will be the first group to be vaccinated. Details are available on www.gov.ky/coronavirus


Will The COVID-19 Vaccine Be Compulsory?

No, it is not compulsory but strongly encouraged.


How Much Does It Cost To Get Vaccinated?

The Government is providing the vaccine without a charge through the Public Health department.


How Many People In The Cayman Islands Will Need To Get Vaccinated To Protect Everyone?

We are aiming that at least 65% of the total population should be vaccinated. This is approximately 44,200 people.


Where Do I Get The COVID-19 Vaccine?

Please visit the Public Health website, to learn where you can get your COVID-19 vaccine. This site will have the information as soon as it becomes available.


What is in the Pfizer/BioNTech Covid-19 vaccine?

The COVID-19 mRNA Vaccine BNT162b2 contains:

  • the active substance, which is BNT162b2 RNA.

Each dose is 0.3 mL with 30 micrograms mRNA.

  • the vaccine contains polyethylene glycol/macrogol (PEG) as part of ALC-0159

The other ingredients are:

  • ALC-0315 = (4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate)
  • ALC-0159 = 2[(polyethylene glycol)-2000]-N,N-ditetradecylacetamide
  • 1,2-Distearoyl-sn-glycero-3-phosphocholine
  • cholesterol
  • potassium chloride
  • potassium dihydrogen phosphate
  • sodium chloride
  • disodium hydrogen phosphate dihydrate
  • sucrose

The vaccine does not contain eggs, preservatives, mercury or antibiotics.


The Pfizer/BioNTech is an mRNA vaccine. What does that mean?

The types of vaccines that currently exist rely on the same basic principle: to stimulate our immune system to responding to a real viral threat by mimicking a natural infection without actually casing you to be sick.
There are four main types of vaccines:
  • inactivated virus (like for polio or rabies or influenza);
  • protein based (e.g. for hepatitis B or whooping cough);
  • viral vector (which includes the AstraZeneca vaccine for COVID-19 and is a similar technology to that for smallpox and Ebola);
  • and the mRNA type. mRNA stands for ‘messenger RiboNucleic Acid’. The mRNA type of vaccine transports the genetic sequence for the spike protein (from the surface of the SARS-CoV-2 virus) into our own cells. Our cells then produce the spike proteins which induce an immune response. This does not cause COVID-19 but means that if the body is exposed to the virus, the immune system would recognise and attack the virus.
The mRNA type of vaccine has so far been produced for COVID-19 disease by two different companies Pfizer/BioNTech and Moderna.

How Many DOSES DO You NeeD Of This COVID-19 Vaccination?

The Pfizer-BioNTech vaccine requires two doses separated by an interval of 21 days for full protection. You will get full protection from this vaccine usually 1–2 weeks after getting your second dose. When you get the vaccine, you will be advised when you need to come back for your second dose.


Can the second dose be given sooner than 21 days?

The Pfizer BioNTech COVID-19 vaccine should not be given less than 19 days after the first dose. Ideally, the interval between doses should be 21 days.


I’m unable to receive the 2nd dose on day 21, what is the window between shots?

The second dose of the Pfizer-BioNTech vaccine may be given up to twelve weeks after the first dose following guidance from the UK’s Joint Committee on Vaccination and Immunisation. If an interval longer than the recommended interval is left between doses, the second dose should still be given. The course will not need to be restarted.


I’m pregnant, can I get the COVID-19 vaccine?

Although there is no known risk associated with vaccines during pregnancy or breastfeeding, we still await more evidence if the vaccine is suitable for pregnant women, and therefore it is not recommended.

The UK’s Joint Committee on Vaccination and Immunisation (JCVI) does not advise routine pregnancy testing before receipt of a COVID-19 vaccine. Those who are trying to become pregnant do not need to avoid pregnancy after vaccination.

If a woman finds out she is pregnant after she has started a course of COVID-19 vaccine, she should complete her pregnancy before finishing the recommended schedule. Women should be offered the vaccine as soon as possible after pregnancy.


What about children?

Children will not be a priority group for a vaccine early in vaccine deployment as vaccine trials have only just begun in children and therefore, there are very limited data for this group. It is worth knowing that children and young people have a very low risk of COVID-19, severe disease or death due to SARS-CoV-2 compared to adults.


I’m immunocompromised. Can I get the COVID-19 vaccine?

Yes. Individuals who are immunosuppressed or have, for example, HIV infection (regardless of CD4 count) should be given COVID-19 vaccine.


I’m healthy, why should I get vaccinated?

COVID-19 can either make you have a sniffle or serious, life-threatening complications; therefore, there is no way to know how COVID-19 will affect you. If you get sick, you could spread the disease to friends, family, and others around you. Getting vaccinated helps towards stopping the pandemic so we can open our borders fully and strengthen our economy.

The Cayman Islands can then go back to a level of normalcy without the fear of getting sick.


Will the COVID-19 vaccine give me COVID-19?

No, the Pfizer/BioNTech COVID-19 vaccine does not have any viable virus particles so the vaccine cannot cause disease. The Pfizer and BioNTech vaccine is an mRNA (messenger ribonucleic acid) vaccine which uses the genetic sequence for the spike protein from the surface of the SARS-CoV-2 virus to enable it to be transported into the cells of the body. The cells then produce the spike proteins which allow our immune system to produce antibodies and activate T-cells to respond to any future encounter.

This does not cause COVID-19 but means that if the body is exposed to the virus, the immune system would recognise and attack the virus.


I heard that the COVID-19 vaccines contain microchips, is this true?

The COVID-19 vaccines do not contain microchips or any electronics.


I have had COVID-19 already, do I need to get vaccinated?

Yes. Due to the life-threatening complications associated with COVID-19 and known cases of re-infection, you are encouraged to get the COVID-19 vaccine even if you had been sick with COVID-19 and have recovered, leaving at least four weeks from the time of infection.

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. Some early evidence suggests natural immunity may not last very long.


Will the vaccine make me infertile?

If you are considering pregnancy soon, accepting the COVID-19 vaccine as soon as it is available to you is a great way to ensure that you — and your pregnancy — are protected. COVID-19 vaccination is not believed to affect future fertility.


Will the vaccine protect me against the new variants that have been seen in the United Kingdom (and elsewhere) and South Africa towards the end of 2020?

It is very reassuring that evidence suggests the current vaccines will protect against these new variants.  Plasma taken from people who have been vaccinated has been shown to ‘neutralise’ these mutations.


Still unsure?

Here is summary of the benefits of COVID-19 vaccination based on what we currently know. The Ministry of Health along with Public will continuously update their information as we learn more.

COVID-19 vaccination will help keep you from getting COVID-19

  • A vaccine will be authorized or approved only if they make it substantially less likely you’ll get COVID-19
  • Being vaccinated will help you protect those you love and care about

COVID-19 vaccination will be a safer way to help build protection

  • COVID-19 can have serious, life-threatening complications, and there is no way to know how COVID-19 will affect you. And if you get sick, you could spread the disease to friends, family, and others around you.
  • Clinical trials of COVID-19 vaccines first show they are safe and effective before any vaccine can be authorized or approved for use. The known and potential benefits of a COVID-19 vaccine must outweigh the known and potential risks of the vaccine for use

COVID-19 vaccination will be an important tool to help stop the pandemic

  • The vaccine will help us to re-open borders and better help the economy to recover
  • Vaccines may help stop the spread of disease
