FAQs about COVID-19 vaccination

  1. How quickly will COVID-19 vaccine stop the pandemic?

Trials have shown several COVID-19 vaccines to have high levels of efficacy, like all other vaccines, COVID-19 vaccines will not be 100% effective. WHO is working to help ensure that approved vaccines are as effective as possible, so they can have the greatest impact on the pandemic.


2. What are the benefits of getting vaccinated?


The COVID-19 vaccines produce protection against the disease, as a result of developing an immune response to the SARS-Cov-2 virus. Developing immunity through vaccination means there is a reduced risk of developing the illness and its consequences. This immunity helps you fight the virus if exposed. Getting vaccinated may also protect people around you because if you are protected from getting infected and from disease, you are less likely to infect someone else. This is particularly important to protect people at increased risk for severe illness from COVID-19, such as healthcare providers, older or elderly adults, and people with other medical conditions.


3. Who should get the vaccine?


The COVID-19 vaccines are safe for most people 18 years and older, including those with pre-existing conditions of any kind, including auto-immune disorders. These conditions include: hypertension, diabetes, asthma, pulmonary, liver and kidney disease, as well as chronic infections that are stable and controlled.

If supplies are limited in your area, discuss your situation with your care provider if you:

  • Have a compromised immune system

  • Are pregnant or nursing your baby

  • Have a history of severe allergies, particularly to a vaccine (or any of the ingredients in the vaccine)

  • Are severely frail

4. Can we stop taking precautions after being vaccinated?


Vaccination protects you from getting seriously ill and dying from COVID-19. For the first fourteen days after getting a vaccination, you do not have significant levels of protection, then it increases gradually. For a single dose vaccine, immunity will generally occur two weeks after vaccination. For two-dose vaccines, both doses are needed to achieve the highest level of immunity possible. While a COVID-19 vaccine will protect you from serious illness and death, we still don’t know the extent to which it keeps you from being infected and passing the virus on to others. To help keep others safe, continue to maintain at least a 1-metre distance from others, cover a cough or sneeze in your elbow, clean your hands frequently and wear a mask, particularly in enclosed, crowded or poorly ventilated spaces. Always follow guidance from local authorities based on the situation and risk where you live.

5. Should the person get the vaccine if he/she has caught COVID-19?


Even if you have already had COVID-19, you should be vaccinated when it is offered to you. The protection that someone gains from having COVID-19 will vary from person to person, and we also don’t know how long natural immunity might last.


6. Is COVID-19 vaccine applicable to children?


Vaccines are tested in adults first, since children's immune system is still developing. The study has proved that the vaccines are safe to adults. The next step will be a further study on the effectiveness on children. Before the study outcomes are proved and clear to the public, children need to follow all COVID protocols--social distance, mask/facial protection if age appropriate, respiratory boutique(cough/sneeze into elbow) and wash hands wash hands wash hands. It is not easy to put all into practice daily for little ones , but their safety is priority :)
